The index of the first character to draw from the given text layout.
The number 0 means to draw from the beginning.
.AP int lastChar in
The index of the last character up to which to draw.  The character
specified by \fIlastChar\fR itself will not be drawn.  A number less
than 0 means to draw all characters in the text layout.
.AP int underline in
Index of the single character to underline in the text layout, or a
negative number counting backwards from the end of the string. Any
out-of-range number (e.g. INT_MIN) means no underline.
.AP int index in
The index of the character whose bounding box is desired.  The bounding
box is computed with respect to the upper-left hand corner of the text layout.
.AP int "*xPtr, *yPtr" out
Filled with the upper-left hand corner, in pixels, of the bounding box
for the character specified by \fIindex\fR.  Either or both \fIxPtr\fR
and \fIyPtr\fR may be NULL, in which case the corresponding value

Although the \fBbindtags\fR command may be used to assign an
arbitrary set of binding tags to a window, the default binding
tags provide the following behavior:
.IP \(bu 3
If a tag is the name of an internal window the binding applies
to that window.
.IP \(bu 3
If the tag is the name of a class of widgets, such as \fBButton\fR,
the binding applies to all widgets in that class.
.IP \(bu 3
If the tag is the name of a toplevel window the binding applies
to the toplevel window and all its internal windows.
.IP \(bu 3



If \fItag\fR has the value \fBall\fR,
the binding applies to all windows in the application.
.SH "EVENT PATTERNS"
.PP
The \fIsequence\fR argument specifies a sequence of one or more
event patterns, with optional white space between the patterns.  Each
event pattern may

and third, and so on. Straight-line segments can be generated within
a curve by duplicating the end-points of the desired line segment.
If the smoothing method is \fBraw\fR, this indicates that the polygon
should also be drawn as a curve but where the list of coordinates is
such that the first coordinate pair (and every third coordinate pair
thereafter) is a knot point on a cubic Bezier curve, and the other
coordinates are control points on the cubic Bezier curve. Straight
line segments can be generated within a curve by making control points
equal to their neighbouring knot points. If the last point is not the
second point of a pair of control points, the point is repeated (one or two
times) so that it also becomes the second point of a pair of control
points (the associated knot point will be the first control point).
.TP
\fB\-splinesteps \fInumber\fR
Specifies the degree of smoothness desired for curves: each spline

This is sent to a text widget when the selection in the widget is
changed.
.TP
\fB<<ThemeChanged>>\fR
This is sent to all widgets when the ttk theme changed. The ttk
widgets listen to this event and redisplay themselves when it fires.
The legacy widgets ignore this event.
.TP
\fB<<TkWorldChanged>>\fR
.
This event is sent to all widgets when a font is changed, for example,
by the use of [font configure].  The user_data field (%d) will have the
value "FontChanged".  For other system wide changes, this event will
be sent to all widgets, and the user_data field will indicate the
cause of the change.  NOTE: all tk and ttk widgets already handle this
event internally.

indicator of which entry of the menu to operate on. These
indicators are called \fIindex\fRes and may be specified in
any of the following forms:
.TP 12
\fBactive\fR
.
Indicates the entry that is currently active.  If no entry is
active then this form is equivalent to \fB{}\fR.  This form may
not be abbreviated.
.TP 12
\fBend\fR
.
Indicates the bottommost entry in the menu.  If there are no
entries in the menu then this form is equivalent to \fB{}\fR.
This form may not be abbreviated.
.TP 12
\fBlast\fR
.
Same as \fBend\fR.
.TP 12
\fB{}\fR
.
Indicates
.QW "no entry at all" ;
this is used most commonly with
the \fBactivate\fR option to deactivate all the entries in the
menu.  In most cases the specification of \fB{}\fR causes
nothing to happen in the widget command.
.TP 12
\fBnone\fR
.
Same as \fB{}\fR
This form may not be abbreviated.
.TP 12
\fB@\fInumber\fR
.
In this form, \fInumber\fR is treated as a y-coordinate in the
menu's window;  the entry closest to that y-coordinate is used.
For example,

The following widget commands are possible for menu widgets:
.TP
\fIpathName \fBactivate \fIindex\fR
.
Change the state of the entry indicated by \fIindex\fR to \fBactive\fR
and redisplay it using its active colors.
Any previously-active entry is deactivated.  If \fIindex\fR
is specified as \fB{}\fR or \fBnone\fR, or if the specified entry is
disabled, then the menu ends up with no active entry.
Returns an empty string.
.TP
\fIpathName \fBadd \fItype \fR?\fIoption value option value ...\fR?
.
Add a new entry to the bottom of the menu.  The new entry's type
is given by \fItype\fR and must be one of \fBcascade\fR,

If no \fIoptions\fR are specified, returns a list describing
the current options for entry \fIindex\fR (see \fBTk_ConfigureInfo\fR for
information on the format of this list).
.TP
\fIpathName \fBindex \fIindex\fR
.
Returns the numerical index corresponding to \fIindex\fR, or
\fB{}\fR if \fIindex\fR was specified as \fB{}\fR or \fBnone\fR.
.TP
\fIpathName \fBinsert \fIindex type \fR?\fIoption value option value ...\fR?
.
Same as the \fBadd\fR widget command except that it inserts the new
entry just before the entry given by \fIindex\fR, instead of appending
to the end of the menu.  The \fItype\fR, \fIoption\fR, and \fIvalue\fR
arguments have the same interpretation as for the \fBadd\fR widget

.SH NAME
print \- Print canvas and text widgets using native dialogs and APIs.
.SH SYNOPSIS
\fBtk print \fIwindow\fR
.
.SH DESCRIPTION
.PP
The \fBtk print\fR command posts a dialog that allows users to print output
from the \fBcanvas\fR and \fBtext\fR widgets. The printing will be done using
platform-native APIs and dialogs where available.
.PP
The \fBcanvas\fR widget has long supported PostScript export and both
PostScript and text files can be sent directly to a printer on Unix-like
systems using the
.QW "lp"
and
.QW "lpr"
Unix commands, and the \fBtk print\fR command does not supersede that
functionality; it builds on it. The \fBtk print\fR command is a fuller
implementation that uses native dialogs on macOS and Windows, and a Tk-based
dialog that provides parallel functionality on X11.
.SH PLATFORM NOTES
.TP
\fBmacOS\fR
.
The Mac implementation uses native print dialogs and relies on the underlying
Common Unix Printing System (CUPS) to render text output from the text widget
and PostScript output from the canvas widget to the printer, to a PDF file, or
a PostScript file.
.TP
\fBWindows\fR
.
The Windows implementation is based on the GDI (Graphics Device Interface)
API. Because there are slight differences in how GDI and Tk's \fBcanvas\fR
widget display graphics, printed output from the \fBcanvas\fR on Windows may
not be identical to screen rendering.
.TP
\fBX11\fR
.
The X11 implementation uses a Tk GUI to configure print jobs for sending to a
printer via the
.QW "lpr"
or
.QW "lp"
commands. While these commands have a large number of parameters for
configuring print jobs, printers vary widely in how they support these
parameters. As a result, only printer selection and number of copies are
configured as arguments to the print command; many aspects of print rendering,
such as grayscale or color for the canvas, are instead configured when
PostScript is generated.

.PP
The \fBtk sysnotify\fR command creates a platform-specific system notification alert. Its intent is to provide a brief, unobtrusive notification to the user by popping up a window that briefly appears in a corner of the screen.
.SH EXAMPLE
.PP
Here is an example of the \fBtk sysnotify\fR code:
.PP
.CS
tk sysnotify "Alert" \e
      "This is just a test of the Tk System Notification Code."
.CE
.SH PLATFORM NOTES
.PP
The macOS and Windows versions are native implementations using system
API's. The X11 version has a conditional dependency on libnotify, and
falls back to a Tcl-only implementation if libnotify is not installed. On
each platform the notification includes a platform-specific default image to
accompany the text.

.TP
\fBmacOS\fR
.
The macOS version will request permission from the user to authorize
notifications. This must be activated in Apple's System Preferences
Notifications section.
.RS
.PP
If deploying an application using the standalone version of Wish.app,
setting the bundle ID in the applications Info.plist file to begin with
.QW \fBcom\fR
seems necessary for notifications to work. Using a different prefix
for the bundle ID, such as something like
.QW \fBtk.tcl.tkchat\fR ,
will cause notifications to silently fail.

\fIsequence\fR (an error occurs if there is no such binding). If both
\fIscript\fR and \fIsequence\fR are omitted then the command returns a list of
all the sequences for which bindings have been defined for \fItagName\fR.
.RS
.PP
The only events for which bindings may be specified are those related to the
mouse and keyboard (such as \fBEnter\fR, \fBLeave\fR, \fBButton\fR,
\fBMotion\fR, and \fBKey\fR) or virtual events. Mouse and keyboard event
bindings for a text widget respectively use the \fBcurrent\fR and \fBinsert\fR
marks described under \fBMARKS\fR above. An
\fBEnter\fR event triggers for a tag when the tag first becomes present on the
current character, and a \fBLeave\fR event triggers for a tag when it ceases
to be present on the current character. \fBEnter\fR and \fBLeave\fR events can
happen either because the \fBcurrent\fR mark moved or because the character at
that position changed. Note that these events are different than \fBEnter\fR
and \fBLeave\fR events for windows. Mouse events are directed to the current
character, while keyboard events are directed to the insert character.
If a virtual event is used in a binding, that binding
can trigger only if the virtual event is defined by an underlying
mouse-related or keyboard-related event.
.PP
It is possible for the current character to have multiple tags, and for each
of them to have a binding for a particular event sequence. When this occurs,
one binding is invoked for each tag, in order from lowest-priority to highest
priority. If there are multiple matching bindings for a single tag, then the

inactivity time is forbidden in safe interpreters and will throw an
error if tried.

\fBtk fontchooser \fIsubcommand\fR ...

\fBtk print \fIwindow\fR

The \fBtk print\fR command posts a dialog that allows users to print output
from the \fBcanvas\fR and \fBtext\fR widgets. The printing will be done using
platform-native APIs and dialogs where available. For more details see the
\fBprint\fR manual page.

\fBtk scaling \fR?\fB\-displayof \fIwindow\fR? ?\fInumber\fR?
.
Sets and queries the current scaling factor used by Tk to convert between
physical units (for example, points, inches, or millimeters) and pixels.  The
\fInumber\fR argument is a floating point number that specifies the number of
pixels per point on \fIwindow\fR's display.  If the \fIwindow\fR argument is

a group of related windows.  The window manager may use this information,
for example, to unmap all of the windows in a group when the group's
leader is iconified.  \fIPathName\fR may be specified as an empty string to
remove \fIwindow\fR from any group association.  If \fIpathName\fR is
specified then the command returns an empty string;  otherwise it
returns the path name of \fIwindow\fR's current group leader, or an empty
string if \fIwindow\fR is not part of any group.
.TP
\fBwm iconbadge \fIwindow\fR \fIbadge\fR
.
Sets a badge for the icon of the \fIwindow\fR. The badge can be a positive
integer number, for instance the number of new or unread messages, or
an exclamation point denoting attention needed. If the badge is an empty
string, the badge image is removed from the application icon. Managing
these changes through bindings, such as <FocusIn>, is the responsibility
of the developer.
.RS
.PP
On X11, for this command to work,
the variable \fB::tk::icons::base_icon($window)\fR must be set to the image that is
being used for the window icon of $window. On Windows and X11, the iconphoto
images work best at 32x32 or a similar dimension, as
the badge images are provided by Tk and drawn to overlay the icon images
using native (Windows) API's or Tk rendering. On macOS, the icon badge is
rendered by a system API and is not provided by Tk. The icon image itself
should be higher-resolution, preferably 512 pixels, to avoid being blurry.
.PP
The icon badge is intended for display in the Dock (macOS), taskbar
(Windows) or app panel (X11). On macOS, the last badge called will be
displayed in the Dock, regardless of how many different icon badges may be
assigned to different windows. On Windows, the taskbar display depends on
whether the taskbar buttons are combined or not (this is an OS setting
available to the user): if combined the behavior is the same as on macOS,
otherwise each button in the taskbar shows the badge it was assigned.
Badge display on macOS is configured in the system preferences. App
panel display behavior on X11 will depend on the window manager and/or
desktop environment.
.RE
.TP
\fBwm iconbitmap \fIwindow\fR ?\fIbitmap\fR?
.
If \fIbitmap\fR is specified, then it names a bitmap in the standard
forms accepted by Tk (see the \fBTk_GetBitmap\fR manual entry for details).
This bitmap is passed to the window manager to be displayed in
\fIwindow\fR's icon, and the command returns an empty string.  If

reflected to the titlebar icons.  Multiple images are accepted to allow
different images sizes (e.g., 16x16 and 32x32) to be provided. The window
manager may scale provided icons to an appropriate size.
.RS
.PP
On Windows, the images are packed into a Windows icon structure.
This will override an ico specified to \fBwm iconbitmap\fR, and
vice versa. This command sets the taskbar icon for the window.
.PP
On X, the images are arranged into the _NET_WM_ICON X property, which
most modern window managers support.  A \fBwm iconbitmap\fR may exist
simultaneously.  It is recommended to use not more than 2 icons, placing
the larger icon first. This command also sets the panel icon for the
application if the window manager or desktop environment supports it.
.PP
On Macintosh, the first image called is loaded into an OSX-native icon
format, and becomes the application icon in dialogs, the Dock, and
other contexts. At the
script level the command will accept only the first image passed in the
parameters as support for multiple sizes/resolutions on macOS is outside Tk's
scope. Developers should use the largest icon they can support

as equivalent to \fBprogram\fR.
Tk will automatically set the position source to \fBuser\fR
when a \fBwm geometry\fR command is invoked, unless the source has
been set explicitly to \fBprogram\fR.
.TP
\fBwm protocol \fIwindow\fR ?\fIname\fR? ?\fIcommand\fR?
.
This command is used to manage window manager protocols. The \fIname\fR

argument in the \fBwm protocol\fR command is the name of an atom corresponding
to a window manager protocol.  Examples include \fBWM_DELETE_WINDOW\fR or
\fBWM_SAVE_YOURSELF\fR or \fBWM_TAKE_FOCUS\fR.


.RS
.PP
A \fIwindow manager protocol\fR is a class of messages sent from a window
manager to a Tk application outside of the normal event processing system. The
main example is the \fBWM_DELETE_WINDOW\fR protocol; these messages are sent
when the user clicks the close widget in the title bar of a window.  Handlers
for window manager protocols are installed with the \fBwm protocol\fR
command. As a rule, if no handler has been installed for a protocol by the
\fBwm protocol\fR command then all messages of that protocol are ignored. The
\fBWM_DELETE_WINDOW\fR protocol is an exception to this rule. At start-up Tk
installs a handler for this protocol, which responds by destroying the
window. The \fBwm protocol\fR command can be used to replace this default
handler by one which responds differently.

.RE
.RS
.PP

The list of available window manager protocols depends on the window manager,
but all window managers supported by Tk provide \fBWM_DELETE_WINDOW\fR. On the
Windows platform, a \fBWM_SAVE_YOURSELF\fR message is sent on user logout
or system restart.
.RE
.RS
.PP
If both \fIname\fR and \fIcommand\fR are specified, then \fIcommand\fR becomes
the handler for the protocol specified by \fIname\fR. The atom for \fIname\fR
will be added to \fIwindow\fR's \fBWM_PROTOCOLS\fR property to tell the window
manager that the application has a handler for the protocol specified by
\fIname\fR, and \fIcommand\fR will be invoked in the future whenever the
window manager sends a message of that protocol to the Tk application.  In
this case the \fBwm protocol\fR command returns an empty string.  If
\fIname\fR is specified but \fIcommand\fR is not, then the current handler for
\fIname\fR is returned, or an empty string if there is no handler defined for
\fIname\fR (as a special case, the default handler for \fBWM_DELETE_WINDOW\fR
is not returned).  If \fIcommand\fR is specified as an empty string then the
atom for \fIname\fR is removed from the \fBWM_PROTOCOLS\fR property of
\fIwindow\fR and the handler is destroyed; an empty string is returned.
Lastly, if neither \fIname\fR nor \fIcommand\fR is specified, the
\fBwm protocol\fR command returns a list of all of the protocols for which
handlers are currently defined for \fIwindow\fR.

Tcl, or Tool Command Language, is an open-source multi-purpose C library which includes a powerful dynamic scripting language. Together they provide ideal cross-platform development environment for any programming project. It has served for decades as an essential system component in organizations ranging from NASA to Cisco Systems, is a must-know language in the fields of EDA, and powers companies such as FlightAware and F5 Networks.

Tcl is fit for both the smallest and largest programming tasks, obviating the need to decide whether it is overkill for a given job or whether a system written in Tcl will scale up as needed. Wherever a shell script might be used Tcl is a better choice, and entire web ecosystems and mission-critical control and testing systems have also been written in Tcl. Tcl excels in all these roles due to the minimal syntax of the language, the unique programming paradigm exposed at the script level, and the careful engineering that has gone into the design of the Tcl internals.
