*** POTENTIAL INCOMPATIBILITY ***

4/12/92 (bug fix) Fixed core dump that occurred in tkError.c when
removing the first error record from the error list.

4/15/92 (bug fix) Fixed bug in tkBind.c that prevented <KeyPress-1>
4/15/92 (bug fix) Fixed bug in tkBind.c that prevented <Key-1>
event specifications from being processed correctly:  the "1" was
treated as a button name rather than a keysym.

4/18/92 (new feature) Added Tk_DefineCursor and Tk_UndefineCursor
procedures.

4/18/92 (new feature) Major revision to listboxes.  Can now scroll and

10/18/96 (new features) A -menu option has been added to the toplevel
widget command, which allows a menu to operate as a menubar. On the
Macintosh, the menubar is displayed accross the top of the main monitor,
just like with other applications. Under Windows and Unix, the menu is
attached to the toplevel window. Also, changed some semantics.
Tearoff menus will now reflect changes to the menu it was
torn off from, and are deleted when the master menu is
torn off from, and are deleted when the main menu is
deleted. Tearoffs also reflect more look-and-feel of the
platforms they are running on. (SRP)

10/31/96 (bug fix) Under Windows, missing system cursors would
generate an error instead of falling through to the Tk cursor of the
same name. (SS)

into account the "-displayof" option.  This problem also existed for the
"font metrics" and "font measure" commands. (CCS)

9/16/97 (new feature) Added "resource delete" and "resource files"
command to the Mac.  Also fixed "resource write" when the resource
was specified by id and already existed. (JI)

9/16/97 (bug fix) Added null bindings to <Command-KeyPress> for the
9/16/97 (bug fix) Added null bindings to <Command-Key> for the
text and entry widget on the Macintosh.  This prevents unbound command
key sequences from having the character echoed to the widget. Also
fixed Cut & Copy bindings.  (JI) (RJ)

9/18/97 (bug fix) Revamped Macintosh focus code.  Cut, Copy & Paste
virtual events now go to the correct (focus) window. (RJ)

Structure that defines the new type of image.
For Tk 8.4 and earlier this must be static: a

.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
is called an \fIimage model\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

.CS
typedef int \fBTk_ImageCreateProc\fR(
        Tcl_Interp *\fIinterp\fR,
        const char *\fIname\fR,

        Tk_ImageModel \fImodel\fR,
        ClientData *\fImodelDataPtr\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
The \fImodel\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.
and create an image model 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
*\fImodelDataPtr\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
Typically the value is a pointer to the model 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

.SH "LEGACY INTERFACE SUPPORT"
.PP
In Tk 8.2 and earlier, the definition of \fBTk_ImageCreateProc\fR
was incompatibly different, with the following prototype:
.CS
typedef int \fBTk_ImageCreateProc\fR(
        Tcl_Interp *\fIinterp\fR,

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.
.PP

use Tk 8.4 headers and stub libraries to do so.
.PP
Any new code written today should not make use of the legacy
interfaces.  Expect their support to go away in Tk 9.

.SH DESCRIPTION
.PP
\fBTk_CreatePhotoImageFormat\fR is invoked to define a new file format
\fBTk_CreatePhotoImageFormatVersion3\fR is invoked to define a new file format
for image data for use with photo images.  The code that implements an
image file format is called an image file format handler, or
handler for short.  The photo image code
maintains a list of handlers that can be used to read and
write data to or from a file.  Some handlers may also
support reading image data from a string or converting image data to a
string format.
The user can specify which handler to use with the \fB\-format\fR
image configuration option or the \fB\-format\fR option to the
\fBread\fR and \fBwrite\fR photo image subcommands.
.PP
The alternate version 2 function \fBTk_CreatePhotoImageFormat\fR has
identical functionality, but does not allow the handler to get or return
the metadata dictionary of the image.
It is described in section \fBVERSION 2 INTERFACE\fR below.
.PP
An image file format handler consists of a collection of procedures
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:
plus a \fBTk_PhotoImageFormatVersion3\fR 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_PhotoImageFormatVersion3 structure contains the following fields:
.VS 8.7
.CS
typedef struct Tk_PhotoImageFormat {
typedef struct Tk_PhotoImageFormatVersion3 {
    const 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;
} \fBTk_PhotoImageFormat\fR;
    Tk_ImageFileMatchProcVersion3 *\fIfileMatchProc\fR;
    Tk_ImageStringMatchProcVersion3 *\fIstringMatchProc\fR;
    Tk_ImageFileReadProcVersion3 *\fIfileReadProc\fR;
    Tk_ImageStringReadProcVersion3 *\fIstringReadProc\fR;

    Tk_ImageStringWriteProcVersion3 *\fIstringWriteProc\fR;
} \fBTk_PhotoImageFormatVersion3\fR;
.CE
.VE 8.7
.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.
.SS 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.
Once \fBTk_CreatePhotoImageFormatVersion3\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).

dictionary as described in section \fBMETADATA INTERFACE\fR below.
If the data in the file appears to be in the format supported by this

.PP
Image formats contain a description of the image bitmap and may
contain additional information like image resolution or comments.

.PP
The metadata may contain any key.
A driver will handle only a set of dictionary keys documented in the

keys for the system drivers.
.PP
The following rules may give guidance to name metadata keys:
.RS
Abreviation are in upper case
.RE

Vertical DPI is expressed as DPI/aspect. The reason is, that some

.SS "METADATA INPUT"
.PP
Each driver function gets a Tcl object pointer \fBmetadataIn\fR as
parameter. This parameter serves to input a metadata dict to the
driver function.
It may be NULL to flag that the metadata dict is empty.
.PP
A typical driver code snipped to check for a metadata key is:
.CS
if (NULL != metadataIn) {
    Tcl_Obj *itemData;
    Tcl_DictObjGet(interp, metadataIn, Tcl_NewStringObj("Comment",-1), &itemData));
.CE
.PP
The \-metadata command option data of the following commands is passed
to the driver: \fBimage create\fR, \fBconfigure\fR, \fBput\fR,
\fBread\fR, \fBdata\fR and \fBwrite\fR.
If no \-metadata command option available or not given, the metadata
property of the image is passed to the driver using the following
commands: \fBcget\fR, \fBconfigure\fR, \fBdata\fR and \fBwrite\fR.
.PP
Note that setting the \-metadata property of an image using
\fBconfigure\fR without any other option does not invoke any driver
function.
.PP
The metadata dictionary is not suited to pass options to the driver
related to the bitmap representation, as the image bitmap is not
recreated on a metadata change. The format string should be used for
this purpose.
.PP
.SS "METADATA OUTPUT"
.PP
The image match and read driver functions may set keys in a prepared
matadata dict to return them.
Those functions get a Tcl object pointer \fBmetadataOut\fR as
parameter.
metadataOut may be NULL to indicate, that no metadata return is
attended(\fBput\fR, \fBread\fR subcommands).
\fBmetadataOut\fR is initialized to an empty unshared dict object if
metadata return is attended (\fBimage create\fR command, \fBconfigure\fR
subcommand). The driver may set dict keys in this object to return
metadata.
If a match function succeeds, the metadataOut pointer is passed to the
corresponding read function.
.PP
A sample driver code snippet is:
.CS
if (NULL != metadataOut) {
    Tcl_DictObjPut(NULL, metadataOut, Tcl_NewStringObj("XMP",-1), Tcl_NewStringObj(xmpMetadata);
.CE
.PP
The metadata keys returned by the driver are merged into the present
metadata property of the image or into the metadata dict given by the
\fB\-metadata\fR command line option.
At the script level, the command \fBimage create\fR and the
\fBconfigure\fR method may return metadata from the driver.
.PP
Format string options or metadata keys may influence the creation of
metadata within the driver.
For example, the creation of an expensive metadata key may depend on a
format string option or on a metadata input key.

\fBTk_AllocFontFromObj\fR and \fBTk_GetFont\fR maintain
a database of all fonts they have allocated.  If
the same font is requested multiple times (e.g. by different
windows or for different purposes), then a single Tk_Font will be
shared for all uses.  The underlying resources will be freed automatically
when no-one is using the font anymore.
.PP
The procedure \fBTk_FontGetDescription\fR returns information about the font
description as a Tcl list. One possible result is "{{DejaVu Sans} -16 bold underline}".
.PP
The procedure \fBTk_NameOfFont\fR is roughly the inverse of
\fBTk_GetFont\fR.  Given a \fItkfont\fR that was created by
\fBTk_GetFont\fR (or \fBTk_AllocFontFromObj\fR), the return value is
the \fIstring\fR argument that was
passed to \fBTk_GetFont\fR to create the font.  The string returned by
\fBTk_NameOfFont\fR is only guaranteed to persist until the \fItkfont\fR
is deleted.  The caller must not modify this string.

When a window manager relinquishes control over a window, or
if it decides that it does not want the window to appear on the
screen under any conditions, it calls \fBTk_UnmaintainGeometry\fR.
\fBTk_UnmaintainGeometry\fR unmaps the window and cancels any
previous calls to \fBTk_MaintainGeometry\fR for the
\fImaster\fR\-\fIslave\fR pair, so that the slave's
\fIcontainer\fR\-\fIwindow\fR pair, so that the window's
geometry and mapped state are no longer maintained
automatically.
\fBTk_UnmaintainGeometry\fR need not be called by a geometry
manager if the slave, the master, or any of the master's ancestors

If \fBTk_MaintainGeometry\fR is called repeatedly for the same
\fImaster\fR\-\fIslave\fR pair, the information from the most
\fIcontainer\fR\-\fIwindow\fR pair, the information from the most
recent call supersedes any older information.
If \fBTk_UnmaintainGeometry\fR is called for a \fImaster\fR\-\fIslave\fR
If \fBTk_UnmaintainGeometry\fR is called for a \fIcontainer\fR\-\fIwindow\fR

\fBTk_Display\fR returns a pointer to the Xlib display structure
corresponding to \fItkwin\fR.  \fBTk_DisplayName\fR returns an
ASCII string identifying \fItkwin\fR's display.  \fBTk_ScreenNumber\fR
returns the index of \fItkwin\fR's screen among all the screens
of \fItkwin\fR's display.  \fBTk_Screen\fR returns a pointer to
the Xlib structure corresponding to \fItkwin\fR's screen.
\fBTk_AlwaysShowSelection\fR indicates whether text/entry widgets
should always display their selection, regardless of window focus.
.PP
\fBTk_X\fR, \fBTk_Y\fR, \fBTk_Width\fR, and \fBTk_Height\fR
return information about \fItkwin's\fR location within its
parent and its size.  The location information refers to the
upper-left pixel in the window, or its border if there is one.
The width and height information refers to the interior size
of the window, not including any border.  \fBTk_Changes\fR

information about the visual characteristics of a window.
\fBTk_Visual\fR returns the visual type for
the window, \fBTk_Depth\fR returns the number of bits per pixel,
and \fBTk_Colormap\fR returns the current
colormap for the window.  The visual characteristics are
normally set from the defaults for the window's screen, but
they may be overridden by calling \fBTk_SetWindowVisual\fR.

.IP \fBMouseWheel\fR 5
Many contemporary mice support a mouse wheel, which is used
for scrolling documents without using the scrollbars.  By rolling the
wheel, the system will generate \fBMouseWheel\fR events that the
application can use to scroll.  Like \fBKey\fR events the event is
always routed to the window that currently has focus. When the event

Horizontal scrolling uses \fBShift-MouseWheel\fR events, with positive
\fB%D\fR \fIdelta\fR substitution indicating left scrolling and negative
right scrolling.
Horizontal scrolling events may fire from
many different hardware units such as tilt wheels or touchpads.  Horizontal
scrolling can also be emulated by holding Shift and scrolling vertically.

Tk supports all of the NSColors in the macOS System ColorList.  The
convention for naming these colors is that the Tk name is generated by
capitalizing the macOS name and adding the prefix "system".  On OSX
10.14 (Mojave) and later many of these "semantic" colors will appear
when Dark Mode is enabled.  However, the change is only observable
when the Apple window manager is drawing to the screen. So the
\fBwinfo rgb\fR command will return the color coordinates used in the

When multiple rows or columns belong to a uniform group, the space
allocated to them is always in proportion to their weights. (A weight

More technically, each row or column in the group will have a size
equal to \fIk*weight\fR for some constant \fIk\fR.  The constant
\fIk\fR is chosen so that no row or column becomes smaller than its
