The value of \fIobjPtr\fR is a standard Tk color name that determines the border colors. The color indicated by \fIobjPtr\fR will not actually be used in the border; it indicates the background color for the window (i.e. a color for flat surfaces). The illuminated portions of the border will appear brighter than indicated by \fIobjPtr\fR, and the shadowed portions of the border will appear darker than \fIobjPtr\fR. .PP \fBTk_Alloc3DBorderFromObj\fR returns a token that may be used in later calls to \fBTk_Draw3DRectangle\fR. If an error occurs in allocating information for the border (e.g. a bogus color name was given) then NULL is returned and an error message is left in \fIinterp->result\fR. If it returns successfully, \fBTk_Alloc3DBorderFromObj\fR caches information about the return value in \fIobjPtr\fR, which speeds up future calls to \fBTk_Alloc3DBorderFromObj\fR with the same \fIobjPtr\fR and \fItkwin\fR. .PP \fBTk_Get3DBorder\fR is identical to \fBTk_Alloc3DBorderFromObj\fR except that the color is specified with a string instead of an object. This prevents \fBTk_Get3DBorder\fR from caching the return value, so \fBTk_Get3DBorder\fR is less efficient than \fBTk_Alloc3DBorderFromObj\fR. .PP \fBTk_Get3DBorderFromObj\fR returns the token for an existing border, given the window and color name used to create the border. \fBTk_Get3DBorderFromObj\fR does not actually create the border; it must already have been created with a previous call to |

It normally returns \fBTCL_OK\fR, but if an error occurs it returns \fBTCL_ERROR\fR and leaves an error message in \fIinterp->result\fR. \fBTk_ClipboardClear\fR must be called before a sequence of \fBTk_ClipboardAppend\fR calls can be issued. .PP \fBTk_ClipboardAppend\fR appends a buffer of data to the clipboard. The first buffer for a given \fItarget\fR determines the \fIformat\fR for that \fItarget\fR. Any successive appends for that \fItarget\fR must have the same format or an error will be returned. \fBTk_ClipboardAppend\fR returns \fBTCL_OK\fR if the buffer is successfully copied onto the clipboard. If the clipboard is not currently owned by the application, either because \fBTk_ClipboardClear\fR has not been called or because ownership of the clipboard has changed since the last call to \fBTk_ClipboardClear\fR, \fBTk_ClipboardAppend\fR returns \fBTCL_ERROR\fR and leaves an error message in \fIinterp->result\fR. .PP In order to guarantee atomicity, no event handling should occur between \fBTk_ClipboardClear\fR and the following \fBTk_ClipboardAppend\fR calls (otherwise someone could retrieve a partially completed clipboard or claim ownership away from this application). .PP \fBTk_ClipboardClear\fR may invoke callbacks, including arbitrary Tcl scripts, as a result of losing the CLIPBOARD selection, so any calling function should take care to be reentrant at the point \fBTk_ClipboardClear\fR is invoked. .SH KEYWORDS append, clipboard, clear, format, type |

The \fIspecs\fR array specifies the kinds of configuration options
expected by the widget. Each of its entries specifies one configuration
option and has the following structure:
.CS
typedef struct {

(e.g. \fBTK_CONFIG_COLOR\fR for a color value, or \fBTK_CONFIG_INT\fR for
an integer value). The \fItype\fR field indicates how to use the
value of the option (more on this below).

This record is assumed to contain information relevant to the manager of the widget; its exact type is unknown to \fBTk_ConfigureWidget\fR. The \fIoffset\fR field of each \fIspecs\fR entry indicates where in \fIwidgRec\fR to store the information about this configuration option.

The location indicated by \fIwidgRec\fR and \fIoffset\fR will be referred to as the .QW target in the descriptions below. .PP The \fItype\fR field of each entry in \fIspecs\fR determines what to do with the string value of that configuration option. The legal values for \fItype\fR, and the corresponding actions, are: .TP \fBTK_CONFIG_ACTIVE_CURSOR\fR The value must be an ASCII string identifying a cursor in a form suitable for passing to \fBTk_GetCursor\fR. The value is converted to a \fBTk_Cursor\fR by calling \fBTk_GetCursor\fR and the result is stored in the target. In addition, the resulting cursor is made the active cursor for \fItkwin\fR by calling \fBXDefineCursor\fR. If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR then the value may be an empty string, in which case the target and \fItkwin\fR's active cursor will be set to \fBNone\fR. |

If \fBTK_CONFIG_NULL_OK\fR is specified in \fIspecFlags\fR and the value is an empty string then the target will be set to NULL. .TP \fBTK_CONFIG_WINDOW\fR The value must be a window path name. It is translated to a \fBTk_Window\fR token and the token is stored in the target. .SH "GROUPED ENTRIES" .PP In some cases it is useful to generate multiple resources from a single configuration value. For example, a color name might be used both to generate the background color for a widget (using \fBTK_CONFIG_COLOR\fR) and to generate a 3-D border to draw around the widget (using \fBTK_CONFIG_BORDER\fR). In cases like this it is possible to specify that several consecutive entries in \fIspecs\fR are to be treated as a group. The first entry is used to determine a value (using its \fIargvName\fR, \fIdbName\fR, \fIdbClass\fR, and \fIdefValue\fR fields). The value will be processed several times (one for each entry in the group), generating multiple different resources and modifying multiple targets within \fIwidgRec\fR.

\fIflags\fR will have a single one of these bits set to select the
entries for the desired widget type. For a working example of
this feature, see the code in tkButton.c.
.SH TK_OFFSET
.PP
The \fBTk_Offset\fR macro is provided as a safe way of generating
the \fIoffset\fR values for entries in Tk_ConfigSpec structures.
It takes two arguments: the name of a type of record, and the
name of a field in that record. It returns the byte offset of
the named field in records of the given type.
.SH TK_CONFIGUREINFO
.PP
The \fBTk_ConfigureInfo\fR procedure may be used to obtain
information about one or all of the options for a given widget.
Given a token for a window (\fItkwin\fR), a table describing the
configuration options for a class of widgets (\fIspecs\fR), a
pointer to a widget record containing the current information for
a widget (\fIwidgRec\fR), and a NULL \fIargvName\fR argument,
\fBTk_ConfigureInfo\fR generates a string describing all of the
configuration options for the window. The string is placed
in \fIinterp->result\fR. Under normal circumstances
it returns \fBTCL_OK\fR; if an error occurs then it returns \fBTCL_ERROR\fR
and \fIinterp->result\fR contains an error message.
.PP
If \fIargvName\fR is NULL, then the value left in
\fIinterp->result\fR by \fBTk_ConfigureInfo\fR
consists of a list of one or more entries, each of which describes
one configuration option (i.e. one entry in \fIspecs\fR). Each
entry in the list will contain either two or five values. If the
corresponding entry in \fIspecs\fR has type \fBTK_CONFIG_SYNONYM\fR, then
the list will contain two values: the \fIargvName\fR for the entry
and the \fIdbName\fR (synonym name). Otherwise the list will contain
five values: \fIargvName\fR, \fIdbName\fR, \fIdbClass\fR, \fIdefValue\fR,
and current value. The current value is computed from the appropriate
field of \fIwidgRec\fR by calling procedures like \fBTk_NameOfColor\fR.
.PP
If the \fIargvName\fR argument to \fBTk_ConfigureInfo\fR is non-NULL,
then it indicates a single option, and information is returned only
for that option. The string placed in \fIinterp->result\fR will be
a list containing two or five values as described above; this will
be identical to the corresponding sublist that would have been returned
if \fIargvName\fR had been NULL.
.PP
The \fIflags\fR argument to \fBTk_ConfigureInfo\fR is used to restrict
the \fIspecs\fR entries to consider, just as for \fBTk_ConfigureWidget\fR.
.SH TK_CONFIGUREVALUE
.PP
\fBTk_ConfigureValue\fR takes arguments similar to \fBTk_ConfigureInfo\fR;
instead of returning a list of values, it just returns the current value
of the option given by \fIargvName\fR (\fIargvName\fR must not be NULL).
The value is returned in \fIinterp->result\fR and \fBTCL_OK\fR is
normally returned as the procedure's result.
If an error occurs in \fBTk_ConfigureValue\fR (e.g., \fIargvName\fR is
not a valid option name), \fBTCL_ERROR\fR is returned and an error message
is left in \fIinterp->result\fR.
This procedure is typically called to implement \fBcget\fR widget
commands.
.SH TK_FREEOPTIONS
.PP
The \fBTk_FreeOptions\fR procedure may be invoked during widget cleanup
to release all of the resources associated with configuration options.
It scans through \fIspecs\fR and for each entry corresponding to a
resource that must be explicitly freed (e.g. those with
type \fBTK_CONFIG_COLOR\fR), it frees the resource in the widget record.
If the field in the widget record does not refer to a resource (e.g.
it contains a null pointer) then no resource is freed for that
entry.
After freeing a resource, \fBTk_FreeOptions\fR sets the
corresponding field of the widget record to null.
.SH "CUSTOM OPTION TYPES"
.PP
Applications can extend the built-in configuration types with additional
configuration types by writing procedures to parse and print options
of the a type and creating a structure pointing to those procedures:
.CS
typedef struct Tk_CustomOption {
Tk_OptionParseProc *\fIparseProc\fR;
Tk_OptionPrintProc *\fIprintProc\fR;
ClientData \fIclientData\fR;
} Tk_CustomOption;
typedef int Tk_OptionParseProc(
ClientData \fIclientData\fR,
Tcl_Interp *\fIinterp\fR,
Tk_Window \fItkwin\fR,
char *\fIvalue\fR,
char *\fIwidgRec\fR,
int \fIoffset\fR);
typedef char *Tk_OptionPrintProc(
ClientData \fIclientData\fR,
Tk_Window \fItkwin\fR,
char *\fIwidgRec\fR,
int \fIoffset\fR,
Tcl_FreeProc **\fIfreeProcPtr\fR);
.CE
The Tk_CustomOption structure contains three fields, which are pointers
to the two procedures and a \fIclientData\fR value to be passed to those
procedures when they are invoked. The \fIclientData\fR value typically
points to a structure containing information that is needed by the
procedures when they are parsing and printing options.

.TH Tk_CreateClientMessageHandler 3 "8.4" Tk "Tk Library Procedures"

.SH NAME
Tk_CreateClientMessageHandler, Tk_DeleteClientMessageHandler \- associate procedure callback with ClientMessage type X events
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR
.sp
\fBTk_CreateClientMessageHandler\fR(\fIproc\fR)
.sp
\fBTk_DeleteClientMessageHandler\fR(\fIproc\fR)
.SH ARGUMENTS
.AP Tk_ClientMessageProc *proc in
Procedure to invoke whenever a ClientMessage X event occurs on any display.
.BE
.SH DESCRIPTION
.PP
\fBTk_CreateClientMessageHandler\fR arranges for \fIproc\fR to be invoked
in the future whenever a ClientMessage X event occurs that is not handled by
\fBWM_PROTOCOL\fR. \fBTk_CreateClientMessageHandler\fR is intended for use
by applications which need to watch X ClientMessage events, such as drag and
drop applications.
.PP
The callback to \fIproc\fR will be made by \fBTk_HandleEvent\fR;
this mechanism only works in programs that dispatch events
through \fBTk_HandleEvent\fR (or through other Tk procedures that
call \fBTk_HandleEvent\fR, such as \fBTcl_DoOneEvent\fR or
\fBTk_MainLoop\fR).
.PP
\fIProc\fR should have arguments and result that match the
type \fBTk_ClientMessageProc\fR:
.CS
typedef int Tk_ClientMessageProc(
Tk_Window \fItkwin\fR,
XEvent *\fIeventPtr\fR);
.CE
The \fItkwin\fR parameter to \fIproc\fR is the Tk window which is
associated with this event. \fIEventPtr\fR is a pointer to the X event.
.PP
Whenever an X ClientMessage event is processed by \fBTk_HandleEvent\fR,
the \fIproc\fR is called if it was not handled as a \fBWM_PROTOCOL\fR.
The return value from \fIproc\fR is normally 0.
A non-zero return value indicates that the event is not to be handled
further; that is, \fIproc\fR has done all processing that is to be
allowed for the event.
.PP
If there are multiple ClientMessage event handlers, each one is called
for each event, in the order in which they were established.
.PP
\fBTk_DeleteClientMessageHandler\fR may be called to delete a
previously-created ClientMessage event handler: it deletes each handler it
finds that matches the \fIproc\fR argument. If no such handler exists,
then \fBTk_DeleteClientMessageHandler\fR returns without doing anything.
Although Tk supports it, it's probably a bad idea to have more than one
callback with the same \fIproc\fR argument.

.TH Tk_CreateGenericHandler 3 "" Tk "Tk Library Procedures"
.so man.macros
.BS
.SH NAME
Tk_CreateGenericHandler, Tk_DeleteGenericHandler \- associate procedure callback with all X events
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR
.sp
\fBTk_CreateGenericHandler\fR(\fIproc, clientData\fR)
.sp
\fBTk_DeleteGenericHandler\fR(\fIproc, clientData\fR)
.SH ARGUMENTS
.AS "Tk_GenericProc" clientData
.AP Tk_GenericProc *proc in
Procedure to invoke whenever any X event occurs on any display.
.AP ClientData clientData in
Arbitrary one-word value to pass to \fIproc\fR.
.BE
.SH DESCRIPTION
.PP
\fBTk_CreateGenericHandler\fR arranges for \fIproc\fR to be
invoked in the future whenever any X event occurs. This mechanism is
\fInot\fR intended for dispatching X events on windows managed by Tk
(you should use \fBTk_CreateEventHandler\fR for this purpose).
\fBTk_CreateGenericHandler\fR is intended for other purposes, such
as tracing X events, monitoring events on windows not owned by Tk,
accessing X-related libraries that were not originally designed for
use with Tk, and so on.
.PP
The callback to \fIproc\fR will be made by \fBTk_HandleEvent\fR;
this mechanism only works in programs that dispatch events
through \fBTk_HandleEvent\fR (or through other Tk procedures that
call \fBTk_HandleEvent\fR, such as \fBTcl_DoOneEvent\fR or
\fBTk_MainLoop\fR).
.PP
\fIProc\fR should have arguments and result that match the
type \fBTk_GenericProc\fR:
.CS
typedef int Tk_GenericProc(
ClientData \fIclientData\fR,
XEvent *\fIeventPtr\fR);
.CE
The \fIclientData\fR parameter to \fIproc\fR is a copy of the \fIclientData\fR
argument given to \fBTk_CreateGenericHandler\fR when the callback
was created. Typically, \fIclientData\fR points to a data
structure containing application-specific information about
how to handle events.
\fIEventPtr\fR is a pointer to the X event.

.BE
.SH DESCRIPTION
.PP
\fBTk_CreateImageType\fR is invoked to define a new kind of image.
An image type corresponds to a particular value of the \fItype\fR
argument for the \fBimage create\fR command. There may exist
any number of different image types, and new types may be defined
dynamically by calling \fBTk_CreateImageType\fR.
For example, there might be one type for 2-color bitmaps,
another for multi-color images, another for dithered images,
another for video, and so on.
.PP
The code that implements a new image type is called an
\fIimage manager\fR.
It consists of a collection of procedures plus three different
kinds of data structures.
The first data structure is a Tk_ImageType structure, which contains
the name of the image type and pointers to five procedures provided
by the image manager to deal with images of this type:
.CS
typedef struct Tk_ImageType {
char *\fIname\fR;
Tk_ImageCreateProc *\fIcreateProc\fR;
Tk_ImageGetProc *\fIgetProc\fR;
Tk_ImageDisplayProc *\fIdisplayProc\fR;
Tk_ImageFreeProc *\fIfreeProc\fR;
Tk_ImageDeleteProc *\fIdeleteProc\fR;
} Tk_ImageType;
.CE
The fields of this structure will be described in later subsections
of this entry.
.PP
The second major data structure manipulated by an image manager
is called an \fIimage master\fR; it contains overall information
about a particular image, such as the values of the configuration
options specified in an \fBimage create\fR command.
There will usually be one of these structures for each
invocation of the \fBimage create\fR command.
.PP
The third data structure related to images is an \fIimage instance\fR.
There will usually be one of these structures for each usage of an
image in a particular widget.
It is possible for a single image to appear simultaneously
in multiple widgets, or even multiple times in the same widget.
Furthermore, different instances may be on different screens
or displays.
The image instance data structure describes things that may
vary from instance to instance, such as colors and graphics
contexts for redisplay.
There is usually one instance structure for each \fB\-image\fR
option specified for a widget or canvas item.
.PP
The following subsections describe the fields of a Tk_ImageType
in more detail.
.SS NAME
.PP
\fItypePtr->name\fR provides a name for the image type.
Once \fBTk_CreateImageType\fR returns, this name may be used
in \fBimage create\fR commands to create images of the new
type.
If there already existed an image type by this name then
the new image type replaces the old one.
.SS CREATEPROC
\fItypePtr->createProc\fR provides the address of a procedure for
Tk to call whenever \fBimage create\fR is invoked to create
an image of the new type.
\fItypePtr->createProc\fR must match the following prototype:
.CS
typedef int Tk_ImageCreateProc(
Tcl_Interp *\fIinterp\fR,
char *\fIname\fR,
int \fIobjc\fR,
Tcl_Obj *const \fIobjv\fR[],
Tk_ImageType *\fItypePtr\fR,
Tk_ImageMaster \fImaster\fR,
ClientData *\fImasterDataPtr\fR);
.CE
The \fIinterp\fR argument is the interpreter in which the \fBimage\fR
command was invoked, and \fIname\fR is the name for the new image,
which was either specified explicitly in the \fBimage\fR command
or generated automatically by the \fBimage\fR command.
The \fIobjc\fR and \fIobjv\fR arguments describe all the configuration
options for the new image (everything after the name argument to
\fBimage\fR).
The \fImaster\fR argument is a token that refers to Tk's information
about this image; the image manager must return this token to
Tk when invoking the \fBTk_ImageChanged\fR procedure.
Typically \fIcreateProc\fR will parse \fIobjc\fR and \fIobjv\fR
and create an image master data structure for the new image.
\fIcreateProc\fR may store an arbitrary one-word value at
*\fImasterDataPtr\fR, which will be passed back to the
image manager when other callbacks are invoked.
Typically the value is a pointer to the master data
structure for the image.
.PP
If \fIcreateProc\fR encounters an error, it should leave an error
message in the interpreter result and return \fBTCL_ERROR\fR; otherwise
it should return \fBTCL_OK\fR.
.PP
\fIcreateProc\fR should call \fBTk_ImageChanged\fR in order to set the
size of the image and request an initial redisplay.
.SS GETPROC
.PP
\fItypePtr->getProc\fR is invoked by Tk whenever a widget
calls \fBTk_GetImage\fR to use a particular image.
This procedure must match the following prototype:
.CS
typedef ClientData Tk_ImageGetProc(
Tk_Window \fItkwin\fR,
ClientData \fImasterData\fR);
.CE
The \fItkwin\fR argument identifies the window in which the
image will be used and \fImasterData\fR is the value
returned by \fIcreateProc\fR when the image master was created.
\fIgetProc\fR will usually create a data structure for the new
instance, including such things as the resources needed to
display the image in the given window.
\fIgetProc\fR returns a one-word token for the instance, which
is typically the address of the instance data structure.
Tk will pass this value back to the image manager when invoking
its \fIdisplayProc\fR and \fIfreeProc\fR procedures.
.SS DISPLAYPROC
.PP
\fItypePtr->displayProc\fR is invoked by Tk whenever an image needs
to be displayed (i.e., whenever a widget calls \fBTk_RedrawImage\fR).
\fIdisplayProc\fR must match the following prototype:
.CS
typedef void Tk_ImageDisplayProc(
ClientData \fIinstanceData\fR,
Display *\fIdisplay\fR,
Drawable \fIdrawable\fR,
int \fIimageX\fR,
int \fIimageY\fR,
int \fIwidth\fR,
int \fIheight\fR,
int \fIdrawableX\fR,
int \fIdrawableY\fR);
.CE
The \fIinstanceData\fR will be the same as the value returned by
\fIgetProc\fR when the instance was created.
\fIdisplay\fR and \fIdrawable\fR indicate where to display the
image; \fIdrawable\fR may be a pixmap rather than
the window specified to \fIgetProc\fR (this is usually the case,
since most widgets double-buffer their redisplay to get smoother
visual effects).
\fIimageX\fR, \fIimageY\fR, \fIwidth\fR, and \fIheight\fR
identify the region of the image that must be redisplayed.
This region will always be within the size of the image
as specified in the most recent call to \fBTk_ImageChanged\fR.
\fIdrawableX\fR and \fIdrawableY\fR indicate where in \fIdrawable\fR
the image should be displayed; \fIdisplayProc\fR should display
the given region of the image so that point (\fIimageX\fR, \fIimageY\fR)
in the image appears at (\fIdrawableX\fR, \fIdrawableY\fR) in \fIdrawable\fR.
.SS FREEPROC
.PP
\fItypePtr->freeProc\fR contains the address of a procedure that
Tk will invoke when an image instance is released (i.e., when
\fBTk_FreeImage\fR is invoked).
This can happen, for example, when a widget is deleted or a image item
in a canvas is deleted, or when the image displayed in a widget or
canvas item is changed.
\fIfreeProc\fR must match the following prototype:
.CS
typedef void Tk_ImageFreeProc(
ClientData \fIinstanceData\fR,
Display *\fIdisplay\fR);
.CE
The \fIinstanceData\fR will be the same as the value returned by
\fIgetProc\fR when the instance was created, and \fIdisplay\fR
is the display containing the window for the instance.
\fIfreeProc\fR should release any resources associated with the
image instance, since the instance will never be used again.
.SS DELETEPROC
.PP
\fItypePtr->deleteProc\fR is a procedure that Tk invokes when an
image is being deleted (i.e. when the \fBimage delete\fR command
is invoked).
Before invoking \fIdeleteProc\fR Tk will invoke \fIfreeProc\fR for
each of the image's instances.
\fIdeleteProc\fR must match the following prototype:
.CS
typedef void Tk_ImageDeleteProc(
ClientData \fImasterData\fR);
.CE
The \fImasterData\fR argument will be the same as the value
stored in \fI*masterDataPtr\fR by \fIcreateProc\fR when the
image was created.
\fIdeleteProc\fR should release any resources associated with
the image.
.SH TK_GETIMAGEMASTERDATA
.PP
The procedure \fBTk_GetImageMasterData\fR may be invoked to retrieve
information about an image. For example, an image manager can use this
procedure to locate its image master data for an image.
If there exists an image named \fIname\fR
in the interpreter given by \fIinterp\fR, then \fI*typePtrPtr\fR is
filled in with type information for the image (the \fItypePtr\fR value
passed to \fBTk_CreateImageType\fR when the image type was registered)
and the return value is the ClientData value returned by the
\fIcreateProc\fR when the image was created (this is typically a
pointer to the image master data structure). If no such image exists
then NULL is returned and NULL is stored at \fI*typePtrPtr\fR.
.SH "LEGACY INTERFACE SUPPORT"
In Tk 8.2 and earlier, the definition of \fBTk_ImageCreateProc\fR
was incompatibly different, with the following prototype:
.CS
typedef int Tk_ImageCreateProc(
Tcl_Interp *\fIinterp\fR,
char *\fIname\fR,
int \fIargc\fR,
char **\fIargv\fR,
Tk_ImageType *\fItypePtr\fR,
Tk_ImageMaster \fImaster\fR,
ClientData *\fImasterDataPtr\fR);
.CE
Legacy programs and libraries dating from those days may still
contain code that defines extended Tk image types using the old
interface. The Tk header file will still support this legacy
interface if the code is compiled with the macro \fBUSE_OLD_IMAGE\fR
defined.

You may find it easier to understand the rest of this manual entry
by looking at the code for an existing canvas item type such as
bitmap (file tkCanvBmap.c) or text (tkCanvText.c).
The easiest way to create a new type manager is to copy the code
for an existing type and modify it for the new type.
.PP
Tk provides a number of utility procedures for the use of canvas
type managers, such as \fBTk_CanvasCoords\fR and \fBTk_CanvasPsColor\fR;
these are described in separate manual entries.
.SH "DATA STRUCTURES"
.PP
A type manager consists of a collection of procedures that provide a
standard set of operations on items of that type.
The type manager deals with three kinds of data
structures.
The first data structure is a Tk_ItemType; it contains
information such as the name of the type and pointers to
the standard procedures implemented by the type manager:
.CS
typedef struct Tk_ItemType {
char *\fIname\fR;
int \fIitemSize\fR;
Tk_ItemCreateProc *\fIcreateProc\fR;
Tk_ConfigSpec *\fIconfigSpecs\fR;
Tk_ItemConfigureProc *\fIconfigProc\fR;
Tk_ItemCoordProc *\fIcoordProc\fR;
Tk_ItemDeleteProc *\fIdeleteProc\fR;
Tk_ItemDisplayProc *\fIdisplayProc\fR;
int \fIalwaysRedraw\fR;
Tk_ItemPointProc *\fIpointProc\fR;
Tk_ItemAreaProc *\fIareaProc\fR;
Tk_ItemPostscriptProc *\fIpostscriptProc\fR;

.PP
The fields of a Tk_ItemType structure are described in more detail
later in this manual entry.
When \fBTk_CreateItemType\fR is called, its \fItypePtr\fR
argument must point to a structure with all of the fields initialized
except \fInextPtr\fR, which Tk sets to link all the types together
into a list.
The structure must be in permanent memory (either statically
allocated or dynamically allocated but never freed); Tk retains
a pointer to this structure.
.PP
The second data structure manipulated by a type manager is an
\fIitem record\fR.
For each item in a canvas there exists one item record.
All of the items of a given type generally have item records with
the same structure, but different types usually have different
formats for their item records.
The first part of each item record is a header with a standard structure
defined by Tk via the type Tk_Item; the rest of the item
record is defined by the type manager.
A type manager must define its item records with a Tk_Item as
the first field.
For example, the item record for bitmap items is defined as follows:
.CS
typedef struct BitmapItem {
Tk_Item \fIheader\fR;
double \fIx\fR, \fIy\fR;
Tk_Anchor \fIanchor\fR;
Pixmap \fIbitmap\fR;
XColor *\fIfgColor\fR;
XColor *\fIbgColor\fR;
GC \fIgc\fR;
} BitmapItem;
.CE
The \fIheader\fR substructure contains information used by Tk
to manage the item, such as its identifier, its tags, its type,
and its bounding box.
The fields starting with \fIx\fR belong to the type manager:
Tk will never read or write them.
The type manager should not need to read or write any of the
fields in the header except for four fields
whose names are \fIx1\fR, \fIy1\fR, \fIx2\fR, and \fIy2\fR.
These fields give a bounding box for the items using integer
canvas coordinates: the item should not cover any pixels
with x-coordinate lower than \fIx1\fR or y-coordinate
lower than \fIy1\fR, nor should it cover any pixels with
x-coordinate greater than or equal to \fIx2\fR or y-coordinate
greater than or equal to \fIy2\fR.
It is up to the type manager to keep the bounding box up to
date as the item is moved and reconfigured.
.PP
Whenever Tk calls a procedure in a type manager it passes in a pointer
to an item record.
The argument is always passed as a pointer to a Tk_Item; the type
manager will typically cast this into a pointer to its own specific
type, such as BitmapItem.
.PP
The third data structure used by type managers has type
Tk_Canvas; it serves as an opaque handle for the canvas widget
as a whole.
Type managers need not know anything about the contents of this
structure.
A Tk_Canvas handle is typically passed in to the
procedures of a type manager, and the type manager can pass the
handle back to library procedures such as Tk_CanvasTkwin
to fetch information about the canvas.
.SS NAME
.PP
This section and the ones that follow describe each of the fields
in a Tk_ItemType structure in detail.
The \fIname\fR field provides a string name for the item type.
Once \fBTk_CreateImageType\fR returns, this name may be used
in \fBcreate\fR widget commands to create items of the new
type.
If there already existed an item type by this name then
the new item type replaces the old one.
.SS ITEMSIZE
\fItypePtr->itemSize\fR gives the size in bytes of item records
of this type, including the Tk_Item header.
Tk uses this size to allocate memory space for items of the type.
All of the item records for a given type must have the same size.
If variable length fields are needed for an item (such as a list
of points for a polygon), the type manager can allocate a separate
object of variable length and keep a pointer to it in the item record.
.SS CREATEPROC
.PP
\fItypePtr->createProc\fR points to a procedure for
Tk to call whenever a new item of this type is created.
\fItypePtr->createProc\fR must match the following prototype:
.CS
typedef int Tk_ItemCreateProc(
Tcl_Interp *\fIinterp\fR,
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIobjc\fR,
Tcl_Obj* const \fIobjv\fR[]);
.CE
The \fIinterp\fR argument is the interpreter in which the canvas's
\fBcreate\fR widget command was invoked, and \fIcanvas\fR is a
handle for the canvas widget.
\fIitemPtr\fR is a pointer to a newly-allocated item of
size \fItypePtr->itemSize\fR.
Tk has already initialized the item's header (the first
\fBsizeof(Tk_ItemType)\fR bytes).
The \fIobjc\fR and \fIobjv\fR arguments describe all of the
arguments to the \fBcreate\fR command after the \fItype\fR
argument.
For example, in the widget command
.CS
\fB\&.c create rectangle 10 20 50 50 \-fill black\fR
.CE
\fIobjc\fR will be \fB6\fR and \fIobjv\fR[0] will contain the
integer object \fB10\fR.
.PP
\fIcreateProc\fR should use \fIobjc\fR and \fIobjv\fR to initialize
the type-specific parts of the item record and set an initial value
for the bounding box in the item's header.
It should return a standard Tcl completion code and leave an
error message in \fIinterp->result\fR if an error occurs.
If an error occurs Tk will free the item record, so \fIcreateProc\fR
must be sure to leave the item record in a clean state if it returns an error
(e.g., it must free any additional memory that it allocated for
the item).
.SS CONFIGSPECS
.PP
Each type manager must provide a standard table describing its
configuration options, in a form suitable for use with
\fBTk_ConfigureWidget\fR.
This table will normally be used by \fItypePtr->createProc\fR
and \fItypePtr->configProc\fR, but Tk also uses it directly
to retrieve option information in the \fBitemcget\fR and
\fBitemconfigure\fR widget commands.
\fItypePtr->configSpecs\fR must point to the configuration table
for this type.
Note: Tk provides a custom option type \fBtk_CanvasTagsOption\fR
for implementing the \fB\-tags\fR option; see an existing type
manager for an example of how to use it in \fIconfigSpecs\fR.
.SS CONFIGPROC
.PP
\fItypePtr->configProc\fR is called by Tk whenever the
\fBitemconfigure\fR widget command is invoked to change the
configuration options for a canvas item.
This procedure must match the following prototype:
.CS
typedef int Tk_ItemConfigureProc(
Tcl_Interp *\fIinterp\fR,
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIobjc\fR,
Tcl_Obj* const \fIobjv\fR[],
int \fIflags\fR);
.CE
The \fIinterp\fR objument identifies the interpreter in which the
widget command was invoked, \fIcanvas\fR is a handle for the canvas
widget, and \fIitemPtr\fR is a pointer to the item being configured.
\fIobjc\fR and \fIobjv\fR contain the configuration options. For
example, if the following command is invoked:
.CS
\fB\&.c itemconfigure 2 \-fill red \-outline black\fR
.CE
\fIobjc\fR is \fB4\fR and \fIobjv\fR contains the string objects \fB\-fill\fR
through \fBblack\fR.
\fIobjc\fR will always be an even value.
The \fIflags\fR argument contains flags to pass to \fBTk_ConfigureWidget\fR;
currently this value is always \fBTK_CONFIG_ARGV_ONLY\fR when Tk
invokes \fItypePtr->configProc\fR, but the type manager's \fIcreateProc\fR
procedure will usually invoke \fIconfigProc\fR with different flag values.
.PP
\fItypePtr->configProc\fR returns a standard Tcl completion code and
leaves an error message in \fIinterp->result\fR if an error occurs.
It must update the item's bounding box to reflect the new configuration
options.
.SS COORDPROC
.PP
\fItypePtr->coordProc\fR is invoked by Tk to implement the \fBcoords\fR
widget command for an item.
It must match the following prototype:
.CS
typedef int Tk_ItemCoordProc(
Tcl_Interp *\fIinterp\fR,
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIobjc\fR,
Tcl_Obj* const \fIobjv\fR[]);
.CE
The arguments \fIinterp\fR, \fIcanvas\fR, and \fIitemPtr\fR
all have the standard meanings, and \fIobjc\fR and \fIobjv\fR
describe the coordinate arguments.
For example, if the following widget command is invoked:
.CS
\fB\&.c coords 2 30 90\fR
.CE
\fIobjc\fR will be \fB2\fR and \fBobjv\fR will contain the integer objects
\fB30\fR and \fB90\fR.
.PP
The \fIcoordProc\fR procedure should process the new coordinates,
update the item appropriately (e.g., it must reset the bounding
box in the item's header), and return a standard Tcl completion
code.
If an error occurs, \fIcoordProc\fR must leave an error message in
\fIinterp->result\fR.
.SS DELETEPROC
.PP
\fItypePtr->deleteProc\fR is invoked by Tk to delete an item
and free any resources allocated to it.
It must match the following prototype:
.CS
typedef void Tk_ItemDeleteProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
Display *\fIdisplay\fR);
.CE
The \fIcanvas\fR and \fIitemPtr\fR arguments have the usual
interpretations, and \fIdisplay\fR identifies the X display containing
the canvas.
\fIdeleteProc\fR must free up any resources allocated for the item,
so that Tk can free the item record.
\fIdeleteProc\fR should not actually free the item record; this will
be done by Tk when \fIdeleteProc\fR returns.
.SS "DISPLAYPROC AND ALWAYSREDRAW"
.PP
\fItypePtr->displayProc\fR is invoked by Tk to redraw an item
on the screen.
It must match the following prototype:
.CS
typedef void Tk_ItemDisplayProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
Display *\fIdisplay\fR,
Drawable \fIdst\fR,
int \fIx\fR,
int \fIy\fR,
int \fIwidth\fR,
int \fIheight\fR);
.CE
The \fIcanvas\fR and \fIitemPtr\fR arguments have the usual meaning.
\fIdisplay\fR identifies the display containing the canvas, and
\fIdst\fR specifies a drawable in which the item should be rendered;
typically this is an off-screen pixmap, which Tk will copy into
the canvas's window once all relevant items have been drawn.
\fIx\fR, \fIy\fR, \fIwidth\fR, and \fIheight\fR specify a rectangular
region in canvas coordinates, which is the area to be redrawn;

\fIdisplayProc\fR should call \fBTk_CanvasDrawableCoords\fR
to transform coordinates from those of the canvas to those
of \fIdst\fR.
.PP
Normally an item's \fIdisplayProc\fR is only invoked if the item
overlaps the area being displayed.
However, if \fItypePtr->alwaysRedraw\fR has a non-zero value, then
\fIdisplayProc\fR is invoked during every redisplay operation,
even if the item does not overlap the area of redisplay.
\fIalwaysRedraw\fR should normally be set to 0; it is only
set to 1 in special cases such as window items that need to be
unmapped when they are off-screen.
.SS POINTPROC
.PP
\fItypePtr->pointProc\fR is invoked by Tk to find out how close
a given point is to a canvas item.
Tk uses this procedure for purposes such as locating the item
under the mouse or finding the closest item to a given point.
The procedure must match the following prototype:
.CS
typedef double Tk_ItemPointProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
double *\fIpointPtr\fR);
.CE
\fIcanvas\fR and \fIitemPtr\fR have the usual meaning.
\fIpointPtr\fR points to an array of two numbers giving
the x and y coordinates of a point.
\fIpointProc\fR must return a real value giving the distance
from the point to the item, or 0 if the point lies inside
the item.
.SS AREAPROC
.PP
\fItypePtr->areaProc\fR is invoked by Tk to find out the relationship
between an item and a rectangular area.
It must match the following prototype:
.CS
typedef int Tk_ItemAreaProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
double *\fIrectPtr\fR);
.CE
\fIcanvas\fR and \fIitemPtr\fR have the usual meaning.
\fIrectPtr\fR points to an array of four real numbers;
the first two give the x and y coordinates of the upper left
corner of a rectangle, and the second two give the x and y
coordinates of the lower right corner.
\fIareaProc\fR must return \-1 if the item lies entirely outside
the given area, 0 if it lies partially inside and partially
outside the area, and 1 if it lies entirely inside the area.
.SS POSTSCRIPTPROC
.PP
\fItypePtr->postscriptProc\fR is invoked by Tk to generate
Postscript for an item during the \fBpostscript\fR widget command.
If the type manager is not capable of generating Postscript then
\fItypePtr->postscriptProc\fR should be NULL.
The procedure must match the following prototype:
.CS
typedef int Tk_ItemPostscriptProc(
Tcl_Interp *\fIinterp\fR,
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIprepass\fR);
.CE
The \fIinterp\fR, \fIcanvas\fR, and \fIitemPtr\fR arguments all have
standard meanings; \fIprepass\fR will be described below.
If \fIpostscriptProc\fR completes successfully, it should append
Postscript for the item to the information in \fIinterp->result\fR
(e.g. by calling \fBTcl_AppendResult\fR, not \fBTcl_SetResult\fR)
and return \fBTCL_OK\fR.
If an error occurs, \fIpostscriptProc\fR should clear the result
and replace its contents with an error message; then it should
return \fBTCL_ERROR\fR.
.PP
Tk provides a collection of utility procedures to simplify
\fIpostscriptProc\fR.
For example, \fBTk_CanvasPsColor\fR will generate Postscript to set
the current color to a given Tk color and \fBTk_CanvasPsFont\fR will
set up font information.

lower left).
.PP
In order to generate Postscript that complies with the Adobe Document
Structuring Conventions, Tk actually generates Postscript in two passes.
It calls each item's \fIpostscriptProc\fR in each pass.
The only purpose of the first pass is to collect font information
(which is done by \fBTk_CanvasPsFont\fR); the actual Postscript is
discarded.
Tk sets the \fIprepass\fR argument to \fIpostscriptProc\fR to 1
during the first pass; the type manager can use \fIprepass\fR to skip
all Postscript generation except for calls to \fBTk_CanvasPsFont\fR.
During the second pass \fIprepass\fR will be 0, so the type manager
must generate complete Postscript.
.SS SCALEPROC
\fItypePtr->scaleProc\fR is invoked by Tk to rescale a canvas item
during the \fBscale\fR widget command.
The procedure must match the following prototype:
.CS
typedef void Tk_ItemScaleProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
double \fIoriginX\fR,
double \fIoriginY\fR,
double \fIscaleX\fR,
double \fIscaleY\fR);
.CE
The \fIcanvas\fR and \fIitemPtr\fR arguments have the usual meaning.
\fIoriginX\fR and \fIoriginY\fR specify an origin relative to which
the item is to be scaled, and \fIscaleX\fR and \fIscaleY\fR give the
x and y scale factors.
The item should adjust its coordinates so that a point in the item
that used to have coordinates \fIx\fR and \fIy\fR will have new
coordinates \fIx\(fm\fR and \fIy\(fm\fR, where
.CS
\fIx\(fm = originX + scaleX*(x-originX)
y\(fm = originY + scaleY*(y-originY)\fR
.CE
\fIscaleProc\fR must also update the bounding box in the item's
header.
.SS TRANSLATEPROC
\fItypePtr->translateProc\fR is invoked by Tk to translate a canvas item
during the \fBmove\fR widget command.
The procedure must match the following prototype:
.CS
typedef void Tk_ItemTranslateProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
double \fIdeltaX\fR,
double \fIdeltaY\fR);
.CE
The \fIcanvas\fR and \fIitemPtr\fR arguments have the usual meaning,
and \fIdeltaX\fR and \fIdeltaY\fR give the amounts that should be
added to each x and y coordinate within the item.
The type manager should adjust the item's coordinates and
update the bounding box in the item's header.
.SS INDEXPROC
\fItypePtr->indexProc\fR is invoked by Tk to translate a string
index specification into a numerical index, for example during the
\fBindex\fR widget command.
It is only relevant for item types that support indexable text;
\fItypePtr->indexProc\fR may be specified as NULL for non-textual
item types.
The procedure must match the following prototype:
.CS
typedef int Tk_ItemIndexProc(
Tcl_Interp *\fIinterp\fR,
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
char \fIindexString\fR,
int *\fIindexPtr\fR);
.CE
The \fIinterp\fR, \fIcanvas\fR, and \fIitemPtr\fR arguments all
have the usual meaning.
\fIindexString\fR contains a textual description of an index,
and \fIindexPtr\fR points to an integer value that should be
filled in with a numerical index.
It is up to the type manager to decide what forms of index
are supported (e.g., numbers, \fBinsert\fR, \fBsel.first\fR,
\fBend\fR, etc.).
\fIindexProc\fR should return a Tcl completion code and set
\fIinterp->result\fR in the event of an error.
.SS ICURSORPROC
.PP
\fItypePtr->icursorProc\fR is invoked by Tk during
the \fBicursor\fR widget command to set the position of the
insertion cursor in a textual item.
It is only relevant for item types that support an insertion cursor;
\fItypePtr->icursorProc\fR may be specified as NULL for item types
that do not support an insertion cursor.
The procedure must match the following prototype:
.CS
typedef void Tk_ItemCursorProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIindex\fR);
.CE
\fIcanvas\fR and \fIitemPtr\fR have the usual meanings, and
\fIindex\fR is an index into the item's text, as returned by a
previous call to \fItypePtr->insertProc\fR.
The type manager should position the insertion cursor in the
item just before the character given by \fIindex\fR.
Whether or not to actually display the insertion cursor is
determined by other information provided by \fBTk_CanvasGetTextInfo\fR.
.SS SELECTIONPROC
.PP
\fItypePtr->selectionProc\fR is invoked by Tk during selection
retrievals; it must return part or all of the selected text in
the item (if any).
It is only relevant for item types that support text;
\fItypePtr->selectionProc\fR may be specified as NULL for non-textual
item types.
The procedure must match the following prototype:
.CS
typedef int Tk_ItemSelectionProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIoffset\fR,
char *\fIbuffer\fR,
int \fImaxBytes\fR);
.CE
\fIcanvas\fR and \fIitemPtr\fR have the usual meanings.
\fIoffset\fR is an offset in bytes into the selection where 0 refers
to the first byte of the selection; it identifies
the first character that is to be returned in this call.
\fIbuffer\fR points to an area of memory in which to store the
requested bytes, and \fImaxBytes\fR specifies the maximum number
of bytes to return.
\fIselectionProc\fR should extract up to \fImaxBytes\fR characters
from the selection and copy them to \fImaxBytes\fR; it should
return a count of the number of bytes actually copied, which may
be less than \fImaxBytes\fR if there are not \fIoffset+maxBytes\fR bytes
in the selection.
.SS INSERTPROC
.PP
\fItypePtr->insertProc\fR is invoked by Tk during
the \fBinsert\fR widget command to insert new text into a
canvas item.
It is only relevant for item types that support text;
\fItypePtr->insertProc\fR may be specified as NULL for non-textual
item types.
The procedure must match the following prototype:
.CS
typedef void Tk_ItemInsertProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIindex\fR,
char *\fIstring\fR);
.CE
\fIcanvas\fR and \fIitemPtr\fR have the usual meanings.
\fIindex\fR is an index into the item's text, as returned by a
previous call to \fItypePtr->insertProc\fR, and \fIstring\fR
contains new text to insert just before the character given
by \fIindex\fR.
The type manager should insert the text and recompute the bounding
box in the item's header.
.SS DCHARSPROC
.PP
\fItypePtr->dCharsProc\fR is invoked by Tk during the \fBdchars\fR
widget command to delete a range of text from a canvas item.
It is only relevant for item types that support text;
\fItypePtr->dCharsProc\fR may be specified as NULL for non-textual
item types.
The procedure must match the following prototype:
.CS
typedef void Tk_ItemDCharsProc(
Tk_Canvas \fIcanvas\fR,
Tk_Item *\fIitemPtr\fR,
int \fIfirst\fR,
int \fIlast\fR);
.CE
\fIcanvas\fR and \fIitemPtr\fR have the usual meanings.
\fIfirst\fR and \fIlast\fR give the indices of the first and last bytes
to be deleted, as returned by previous calls to \fItypePtr->indexProc\fR.
The type manager should delete the specified characters and update
the bounding box in the item's header.

plus a Tk_PhotoImageFormat structure, which contains the name of the
image file format and pointers to six procedures provided by the
handler to deal with files and strings in this format. The
Tk_PhotoImageFormat structure contains the following fields:
.CS
typedef struct Tk_PhotoImageFormat {
char *\fIname\fR;
Tk_ImageFileMatchProc *\fIfileMatchProc\fR;
Tk_ImageStringMatchProc *\fIstringMatchProc\fR;
Tk_ImageFileReadProc *\fIfileReadProc\fR;
Tk_ImageStringReadProc *\fIstringReadProc\fR;
Tk_ImageFileWriteProc *\fIfileWriteProc\fR;
Tk_ImageStringWriteProc *\fIstringWriteProc\fR;
} Tk_PhotoImageFormat;
.CE
.PP
The handler need not provide implementations of all six procedures.
For example, the procedures that handle string data would not be
provided for a format in which the image data are stored in binary,
and could therefore contain null characters. If any procedure is not
implemented, the corresponding pointer in the Tk_PhotoImageFormat
structure should be set to NULL. The handler must provide the
\fIfileMatchProc\fR procedure if it provides the \fIfileReadProc\fR
procedure, and the \fIstringMatchProc\fR procedure if it provides the
\fIstringReadProc\fR procedure.
.SH NAME
.PP
\fIformatPtr->name\fR provides a name for the image type.
Once \fBTk_CreatePhotoImageFormat\fR returns, this name may be used
in the \fB\-format\fR photo image configuration and subcommand option.
The manual page for the photo image (photo(n)) describes how image
file formats are chosen based on their names and the value given to
the \fB\-format\fR option. The first character of \fIformatPtr->name\fR
must not be an uppercase character from the ASCII character set
(that is, one of the characters \fBA\fR-\fBZ\fR). Such names are used
only for legacy interface support (see below).
.SH FILEMATCHPROC
\fIformatPtr->fileMatchProc\fR provides the address of a procedure for
Tk to call when it is searching for an image file format handler
suitable for reading data in a given file.
\fIformatPtr->fileMatchProc\fR must match the following prototype:
.CS
typedef int Tk_ImageFileMatchProc(
Tcl_Channel \fIchan\fR,
const char *\fIfileName\fR,
Tcl_Obj *\fIformat\fR,
int *\fIwidthPtr\fR,
int *\fIheightPtr\fR,
Tcl_Interp *\fIinterp\fR);
.CE
The \fIfileName\fR argument is the name of the file containing the
image data, which is open for reading as \fIchan\fR. The
\fIformat\fR argument contains the value given for the
\fB\-format\fR option, or NULL if the option was not specified.
If the data in the file appears to be in the format supported by this
handler, the \fIformatPtr->fileMatchProc\fR procedure should store the
width and height of the image in *\fIwidthPtr\fR and *\fIheightPtr\fR
respectively, and return 1. Otherwise it should return 0.
.SH STRINGMATCHPROC
\fIformatPtr->stringMatchProc\fR provides the address of a procedure for
Tk to call when it is searching for an image file format handler for
suitable for reading data from a given string.
\fIformatPtr->stringMatchProc\fR must match the following prototype:
.CS
typedef int Tk_ImageStringMatchProc(
Tcl_Obj *\fIdata\fR,
Tcl_Obj *\fIformat\fR,
int *\fIwidthPtr\fR,
int *\fIheightPtr\fR,
Tcl_Interp *\fIinterp\fR);
.CE
The \fIdata\fR argument points to the object containing the image
data. The \fIformat\fR argument contains the value given for
the \fB\-format\fR option, or NULL if the option was not specified.
If the data in the string appears to be in the format supported by
this handler, the \fIformatPtr->stringMatchProc\fR procedure should
store the width and height of the image in *\fIwidthPtr\fR and
*\fIheightPtr\fR respectively, and return 1. Otherwise it should
return 0.
.SH FILEREADPROC
\fIformatPtr->fileReadProc\fR provides the address of a procedure for
Tk to call to read data from an image file into a photo image.
\fIformatPtr->fileReadProc\fR must match the following prototype:
.CS
typedef int Tk_ImageFileReadProc(
Tcl_Interp *\fIinterp\fR,
Tcl_Channel \fIchan\fR,
const char *\fIfileName\fR,
Tcl_Obj *\fIformat\fR,
PhotoHandle \fIimageHandle\fR,
int \fIdestX\fR, int \fIdestY\fR,
int \fIwidth\fR, int \fIheight\fR,
int \fIsrcX\fR, int \fIsrcY\fR);
.CE
The \fIinterp\fR argument is the interpreter in which the command was
invoked to read the image; it should be used for reporting errors.
The image data is in the file named \fIfileName\fR, which is open for
reading as \fIchan\fR. The \fIformat\fR argument contains the
value given for the \fB\-format\fR option, or NULL if the option was
not specified. The image data in the file, or a subimage of it, is to
be read into the photo image identified by the handle
\fIimageHandle\fR. The subimage of the data in the file is of
dimensions \fIwidth\fR x \fIheight\fR and has its top-left corner at
coordinates (\fIsrcX\fR,\fIsrcY\fR). It is to be stored in the photo
image with its top-left corner at coordinates
(\fIdestX\fR,\fIdestY\fR) using the \fBTk_PhotoPutBlock\fR procedure.
The return value is a standard Tcl return value.
.SH STRINGREADPROC
\fIformatPtr->stringReadProc\fR provides the address of a procedure for
Tk to call to read data from a string into a photo image.
\fIformatPtr->stringReadProc\fR must match the following prototype:
.CS
typedef int Tk_ImageStringReadProc(
Tcl_Interp *\fIinterp\fR,
Tcl_Obj *\fIdata\fR,
Tcl_Obj *\fIformat\fR,
PhotoHandle \fIimageHandle\fR,
int \fIdestX\fR, int \fIdestY\fR,
int \fIwidth\fR, int \fIheight\fR,
int \fIsrcX\fR, int \fIsrcY\fR);
.CE
The \fIinterp\fR argument is the interpreter in which the command was
invoked to read the image; it should be used for reporting errors.
The \fIdata\fR argument points to the image data in object form.
The \fIformat\fR argument contains the
value given for the \fB\-format\fR option, or NULL if the option was
not specified. The image data in the string, or a subimage of it, is to
be read into the photo image identified by the handle
\fIimageHandle\fR. The subimage of the data in the string is of
dimensions \fIwidth\fR x \fIheight\fR and has its top-left corner at
coordinates (\fIsrcX\fR,\fIsrcY\fR). It is to be stored in the photo
image with its top-left corner at coordinates
(\fIdestX\fR,\fIdestY\fR) using the \fBTk_PhotoPutBlock\fR procedure.
The return value is a standard Tcl return value.
.SH FILEWRITEPROC
\fIformatPtr->fileWriteProc\fR provides the address of a procedure for
Tk to call to write data from a photo image to a file.
\fIformatPtr->fileWriteProc\fR must match the following prototype:
.CS
typedef int Tk_ImageFileWriteProc(
Tcl_Interp *\fIinterp\fR,
const char *\fIfileName\fR,
Tcl_Obj *\fIformat\fR,
Tk_PhotoImageBlock *\fIblockPtr\fR);
.CE
The \fIinterp\fR argument is the interpreter in which the command was
invoked to write the image; it should be used for reporting errors.
The image data to be written are in memory and are described by the
Tk_PhotoImageBlock structure pointed to by \fIblockPtr\fR; see the
manual page FindPhoto(3) for details. The \fIfileName\fR argument
points to the string giving the name of the file in which to write the
image data. The \fIformat\fR argument contains the
value given for the \fB\-format\fR option, or NULL if the option was
not specified. The format string can contain extra characters
after the name of the format. If appropriate, the
\fIformatPtr->fileWriteProc\fR procedure may interpret these
characters to specify further details about the image file.
The return value is a standard Tcl return value.
.SH STRINGWRITEPROC
\fIformatPtr->stringWriteProc\fR provides the address of a procedure for
Tk to call to translate image data from a photo image into a string.
\fIformatPtr->stringWriteProc\fR must match the following prototype:
.CS
typedef int Tk_ImageStringWriteProc(
Tcl_Interp *\fIinterp\fR,
Tcl_Obj *\fIformat\fR,
Tk_PhotoImageBlock *\fIblockPtr\fR);
.CE
The \fIinterp\fR argument is the interpreter in which the command was
invoked to convert the image; it should be used for reporting errors.
The image data to be converted are in memory and are described by the
Tk_PhotoImageBlock structure pointed to by \fIblockPtr\fR; see the
manual page FindPhoto(3) for details. The data for the string
should be put in the interpreter \fIinterp\fR result.
The \fIformat\fR argument contains the
value given for the \fB\-format\fR option, or NULL if the option was
not specified. The format string can contain extra characters
after the name of the format. If appropriate, the
\fIformatPtr->stringWriteProc\fR procedure may interpret these
characters to specify further details about the image file.
The return value is a standard Tcl return value.
.SH "LEGACY INTERFACE SUPPORT"
In Tk 8.2 and earlier, the definition of all the function pointer
types stored in fields of a \fBTk_PhotoImageFormat\fR struct were
incompatibly different. Legacy programs and libraries dating from
those days may still contain code that defines extended Tk photo image
formats using the old interface. The Tk header file will still support
this legacy interface if the code is compiled with the
macro \fBUSE_OLD_IMAGE\fR defined. Alternatively, the legacy interfaces

.SH NAME
Tk_CreateEventHandler, Tk_DeleteEventHandler \- associate procedure callback with an X event
.SH SYNOPSIS

.sp
\fBTk_CreateEventHandler\fR(\fItkwin, mask, proc, clientData\fR)
.sp
\fBTk_DeleteEventHandler\fR(\fItkwin, mask, proc, clientData\fR)
.SH ARGUMENTS
.AS "unsigned long" clientData
.AP Tk_Window tkwin in
Token for window in which events may occur.
.AP "unsigned long" mask in
Bit-mask of events (such as \fBButtonPressMask\fR)
for which \fIproc\fR should be called.
.AP Tk_EventProc *proc in
Procedure to invoke whenever an event in \fImask\fR occurs
in the window given by \fItkwin\fR.
.AP ClientData clientData in
Arbitrary one-word value to pass to \fIproc\fR.
.BE
.SH DESCRIPTION
.PP
\fBTk_CreateEventHandler\fR arranges for \fIproc\fR to be
invoked in the future whenever one of the event types specified
by \fImask\fR occurs in the window specified by \fItkwin\fR.
The callback to \fIproc\fR will be made by \fBTk_HandleEvent\fR;
this mechanism only works in programs that dispatch events
through \fBTk_HandleEvent\fR (or through other Tk procedures that
call \fBTk_HandleEvent\fR, such as \fBTcl_DoOneEvent\fR or
\fBTk_MainLoop\fR).
.PP
\fIProc\fR should have arguments and result that match the
type \fBTk_EventProc\fR:
.CS
typedef void Tk_EventProc(
ClientData \fIclientData\fR,
XEvent *\fIeventPtr\fR);
.CE
The \fIclientData\fR parameter to \fIproc\fR is a copy of the \fIclientData\fR
argument given to \fBTk_CreateEventHandler\fR when the callback
was created. Typically, \fIclientData\fR points to a data
structure containing application-specific information about
the window in which the event occurred. \fIEventPtr\fR is
a pointer to the X event, which will be one of the ones

.CE
The \fIpixelPtr\fR field points to the first pixel, that is, the
top-left pixel in the block.
The \fIwidth\fR and \fIheight\fR fields specify the dimensions of the
block of pixels. The \fIpixelSize\fR field specifies the address
difference between two horizontally adjacent pixels. Often it is 3
or 4, but it can have any value. The \fIpitch\fR field specifies the
address difference between two vertically adjacent pixels. The
\fIoffset\fR array contains the offsets from the address of a pixel
to the addresses of the bytes containing the red, green, blue and alpha
(transparency) components. These are normally 0, 1, 2 and 3, but can
have other values, e.g., for images that are stored as separate red,
green and blue planes.
.PP
The \fIcompRule\fR parameter to \fBTk_PhotoPutBlock\fR specifies a
compositing rule that says what to do with transparent pixels. The
value \fBTK_PHOTO_COMPOSITE_OVERLAY\fR says that the previous contents of
the photo image should show through, and the value
\fBTK_PHOTO_COMPOSITE_SET\fR says that the previous contents of the photo
image should be completely ignored, and the values from the block be
copied directly across. The behavior in Tk8.3 and earlier was
equivalent to having \fBTK_PHOTO_COMPOSITE_OVERLAY\fR as a compositing rule.
.PP
The value given for the \fIwidth\fR and \fIheight\fR parameters to
\fBTk_PhotoPutBlock\fR do not have to correspond to the values specified
in \fIblock\fR. If they are smaller, \fBTk_PhotoPutBlock\fR extracts a
sub-block from the image data supplied. If they are larger, the data
given are replicated (in a tiled fashion) to fill the specified area.
These rules operate independently in the horizontal and vertical
directions.
.PP
.VS 8.5
\fBTk_PhotoPutBlock\fR normally returns \fBTCL_OK\fR, though if it cannot
allocate sufficient memory to hold the resulting image, \fBTCL_ERROR\fR is
returned instead and, if the \fIinterp\fR argument is non-NULL, an
error message is placed in the interpreter's result.
.VE 8.5
.PP
\fBTk_PhotoPutZoomedBlock\fR works like \fBTk_PhotoPutBlock\fR except that
the image can be reduced or enlarged for display. The
\fIsubsampleX\fR and \fIsubsampleY\fR parameters allow the size of the
image to be reduced by subsampling.
\fBTk_PhotoPutZoomedBlock\fR will use only pixels from the input image
whose X coordinates are multiples of \fIsubsampleX\fR, and whose Y

The values are valid until the image is destroyed or its size is changed. \fBTk_PhotoGetImage\fR returns 1 for compatibility with the corresponding procedure in the old photo widget. .PP \fBTk_PhotoBlank\fR blanks the entire area of the photo image. Blank areas of a photo image are transparent. .PP \fBTk_PhotoExpand\fR requests that the widget's image be expanded to be at least \fIwidth\fR x \fIheight\fR pixels in size. The width and/or height are unchanged if the user has specified an explicit image width or height with the \fB\-width\fR and/or \fB\-height\fR configuration options, respectively. If the image data are being supplied in many small blocks, it is more efficient to use \fBTk_PhotoExpand\fR or \fBTk_PhotoSetSize\fR at the beginning rather than allowing the image to expand in many small increments as image blocks are supplied. .PP .VS 8.5 \fBTk_PhotoExpand\fR normally returns \fBTCL_OK\fR, though if it cannot allocate sufficient memory to hold the resulting image, \fBTCL_ERROR\fR is returned instead and, if the \fIinterp\fR argument is non-NULL, an error message is placed in the interpreter's result. .VE 8.5 .PP \fBTk_PhotoSetSize\fR specifies the size of the image, as if the user had specified the given \fIwidth\fR and \fIheight\fR values to the \fB\-width\fR and \fB\-height\fR configuration options. A value of zero for \fIwidth\fR or \fIheight\fR does not change the image's width or height, but allows the width or height to be changed by subsequent calls to \fBTk_PhotoPutBlock\fR, \fBTk_PhotoPutZoomedBlock\fR or \fBTk_PhotoExpand\fR. .PP .VS 8.5 \fBTk_PhotoSetSize\fR normally returns \fBTCL_OK\fR, though if it cannot allocate sufficient memory to hold the resulting image, \fBTCL_ERROR\fR is returned instead and, if the \fIinterp\fR argument is non-NULL, an error message is placed in the interpreter's result. .VE 8.5 .PP \fBTk_PhotoGetSize\fR returns the dimensions of the image in *\fIwidthPtr\fR and *\fIheightPtr\fR. .SH PORTABILITY .PP In Tk 8.3 and earlier, \fBTk_PhotoPutBlock\fR and \fBTk_PhotoPutZoomedBlock\fR had different signatures. If you want to compile code that uses the old interface against 8.4 without updating your code, compile it with the flag -DUSE_COMPOSITELESS_PHOTO_PUT_BLOCK.

.PP
Given a \fItkfont\fR, \fBTk_FontId\fR returns the token that should be
selected into an XGCValues structure in order to construct a graphics
context that can be used to draw text in the specified font.
.PP
\fBTk_GetFontMetrics\fR computes the ascent, descent, and linespace of the
\fItkfont\fR in pixels and stores those values in the structure pointer to by
\fIfmPtr\fR. These values can be used in computations such as to space
multiple lines of text, to align the baselines of text in different
fonts, and to vertically align text in a given region. See the
documentation for the \fBfont\fR command for definitions of the terms
ascent, descent, and linespace, used in font metrics.
.PP
\fBTk_PostscriptFontName\fR maps a \fItkfont\fR to the corresponding
Postscript font name that should be used when printing. The return value
is the size in points of the \fItkfont\fR and the Postscript font name is
appended to \fIdsPtr\fR. \fIDsPtr\fR must refer to an initialized
\fBTcl_DString\fR. Given a
.QW reasonable
Postscript printer, the
following screen font families should print correctly:
.IP

\fBTimes\fR, \fBTimes New Roman\fR, \fBZapf Chancery\fR, and
\fBZapf Dingbats\fR.
.PP
Any other font families may not print correctly because the computed
Postscript font name may be incorrect or not exist on the printer.
.SH "DATA STRUCTURES"
The \fBTk_FontMetrics\fR data structure is used by \fBTk_GetFontMetrics\fR to

letter sticks up above the baseline, plus any extra blank space added
by the designer of the font.

If a long-running application reaches the end of the resource id space, it will generate an X protocol error and crash. Tk replaces the default id allocator with its own allocator, which allows identifiers to be reused. In order for this to work, \fBTk_FreeXId\fR must be called to tell the allocator about resources that have been freed. Tk automatically calls \fBTk_FreeXId\fR whenever it frees a resource, so if you use procedures like \fBTk_GetFont\fR, \fBTk_GetGC\fR, and \fBTk_GetPixmap\fR then you need not call \fBTk_FreeXId\fR. However, if you allocate resources directly from Xlib, for example by calling \fBXCreatePixmap\fR, then you should call \fBTk_FreeXId\fR when you call the corresponding Xlib free procedure, such as \fBXFreePixmap\fR. If you do not call \fBTk_FreeXId\fR then the resource identifier will be lost, which could cause problems if the application runs long enough to lose all of the available identifiers. .SH KEYWORDS resource identifier |

.TH Tk_GetDash 3 8.3 Tk "Tk Library Procedures"
.so man.macros
.BS
.SH NAME
Tk_GetDash \- convert from string to valid dash structure.
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR
.sp
int
\fBTk_GetDash\fR(\fIinterp, string, dashPtr\fR)
.SH ARGUMENTS
.AS Tk_Dash *dashPtr
.AP Tcl_Interp *interp in
Interpreter to use for error reporting.
.AP "const char *" string in
Textual value to be converted.
.AP Tk_Dash *dashPtr out
Points to place to store the dash pattern
value converted from \fIstring\fR.
.BE
.SH DESCRIPTION
.PP
These procedure parses the string and fills in the result in the
Tk_Dash structure. The string can be a list of integers or a
character string containing only
.QW \fB.,\-_\fR
or spaces. If all
goes well, \fBTCL_OK\fR is returned. If \fIstring\fR does not have the
proper syntax then \fBTCL_ERROR\fR is returned, an error message is left
in the interpreter's result, and nothing is stored at *\fIdashPtr\fR.
.PP
The first possible syntax is a list of integers. Each element
represents the number of pixels of a line segment. Only the odd
segments are drawn using the
.QW outline
color. The other segments are drawn transparent.
.PP
The second possible syntax is a character list containing only
5 possible characters
.QW "\fB.,\-_ \fR" .
The space can be used
to enlarge the space between other line elements, and can not
occur as the first position in the string. Some examples:
.CS
\-dash . = \-dash {2 4}
\-dash \- = \-dash {6 4}
\-dash \-. = \-dash {6 4 2 4}
\-dash \-.. = \-dash {6 4 2 4 2 4}
\-dash {. } = \-dash {2 8}
\-dash , = \-dash {4 4}
.CE
.PP
The main difference of this syntax with the previous is that it
is shape-conserving. This means that all values in the dash
list will be multiplied by the line width before display. This
assures that
.QW .
will always be displayed as a dot and
.QW \-
always as a dash regardless of the line width.
.PP
On systems where only a limited set of dash patterns, the dash
pattern will be displayed as the most close dash pattern that
is available. For example, on Windows only the first 4 of the
above examples are available. The last 2 examples will be
displayed identically as the first one.

dash, conversion

The \fIchangeProc\fR and \fIclientData\fR arguments to
\fBTk_GetImage\fR are used for this purpose.
\fIchangeProc\fR will be called by Tk whenever a change occurs
in the image; it must match the following prototype:
.CS
typedef void Tk_ImageChangedProc(
ClientData \fIclientData\fR,
int \fIx\fR,

int \fIwidth\fR,
int \fIheight\fR,

int \fIimageHeight\fR);
.CE
The \fIclientData\fR argument to \fIchangeProc\fR is the same as the
\fIclientData\fR argument to \fBTk_GetImage\fR.
It is usually a pointer to the widget record for the widget or
some other data structure managed by the widget.
The arguments \fIx\fR, \fIy\fR, \fIwidth\fR, and \fIheight\fR
identify a region within the image that must be redisplayed;
they are specified in pixels measured from the upper-left
corner of the image.
The arguments \fIimageWidth\fR and \fIimageHeight\fR give
the image's (new) size.

If there is an option for \fItkwin\fR that matches the given \fIname\fR or \fIclass\fR, then it is returned in the form of a Tk_Uid. If multiple options match \fIname\fR and \fIclass\fR, then the highest-priority one is returned. If no option matches, then NULL is returned. .PP \fBTk_GetOption\fR caches options related to \fItkwin\fR so that successive calls for the same \fItkwin\fR will execute much more quickly than successive calls for different windows. .SH KEYWORDS class, name, option, retrieve | > > | 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 | Token for window. .AP "const char" *name in Name of desired option. .AP "const char" *class in Class of desired option.
