.TH tk n 8.4 Tk "Tk Built-In Commands"
.BS
'\" Note:  do not modify the .SH NAME line immediately below!
.SH NAME
tk \- Manipulate Tk internal state
.SH SYNOPSIS
\fBtk\fR \fIoption \fR?\fIarg arg ...\fR?
.BE

.SH DESCRIPTION
.PP
The \fBtk\fR command provides access to miscellaneous
elements of Tk's internal state.
Most of the information manipulated by this command pertains to the
application as a whole, or to a screen or display, rather than to a
particular window.
The command can take any of a number of different forms
depending on the \fIoption\fR argument.  The legal forms are:
.TP
\fBtk appname \fR?\fInewName\fR?
If \fInewName\fR isn't specified, this command returns the name
of the application (the name that may be used in \fBsend\fR
commands to communicate with the application).
If \fInewName\fR is specified, then the name of the application
is changed to \fInewName\fR.
If the given name is already in use, then a suffix of the form
``\fB #2\fR'' or ``\fB #3\fR'' is appended in order to make the name unique.
The command's result is the name actually chosen.
\fInewName\fR should not start with a capital letter.
This will interfere with option processing, since names starting with
capitals are assumed to be classes;  as a result, Tk may not
be able to find some options for the application.
If sends have been disabled by deleting the \fBsend\fR command,
this command will reenable them and recreate the \fBsend\fR
command.
.VS 8.4
.TP
\fBtk caret window \fR?\fB\-x \fIx\fR? ?\fB\-y \fIy\fR? ?\fB\-height \fIheight\fR?
.
Sets and queries the caret location for the display of the specified
Tk window \fIwindow\fR.  The caret is the per-display cursor location
used for indicating global focus (e.g. to comply with Microsoft
Accessibility guidelines), as well as for location of the over-the-spot
XIM (X Input Methods) or Windows IME windows.  If no options are specified,
the last values used for setting the caret are return in option-value pair
format.  \fI\-x\fR and \fI\-y\fR represent window-relative coordinates, and
\fI\-height\fR is the height of the current cursor location, or the height
of the specified \fIwindow\fR if none is given.
.VE
.TP
\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
omitted, it defaults to the main window.  If the \fInumber\fR argument is 
omitted, the current value of the scaling factor is returned.
.RS
.PP
A ``point'' is a unit of measurement equal to 1/72 inch.  A scaling factor
of 1.0 corresponds to 1 pixel per point, which is equivalent to a standard
72 dpi monitor.  A scaling factor of 1.25 would mean 1.25 pixels per point,
which is the setting for a 90 dpi monitor; setting the scaling factor to
1.25 on a 72 dpi monitor would cause everything in the application to be
displayed 1.25 times as large as normal.  The initial value for the scaling
factor is set when the application starts, based on properties of the
installed monitor, but it can be changed at any time.  Measurements made
after the scaling factor is changed will use the new scaling factor, but it
is undefined whether existing widgets will resize themselves dynamically to
accomodate the new scaling factor.
.RE
.VS 8.3
.TP
\fBtk useinputmethods \fR?\fB\-displayof \fIwindow\fR? ?\fIboolean\fR?
.
Sets and queries the state of whether Tk should use XIM (X Input Methods)
for filtering events.  The resulting state is returned.  XIM is used in
some locales (ie: Japanese, Korean), to handle special input devices.  This
feature is only significant on X.  If XIM support is not available, this
will always return 0.  If the \fIwindow\fR argument is omitted, it defaults
to the main window.  If the \fIboolean\fR argument is omitted, the current
state is returned.  This is turned on by default for the main display.
.VE
.VS 8.4
.TP
\fBtk windowingsystem\fR
.
Returns the current Tk windowing system, one of
\fBx11\fR (X11-based), \fBwin32\fR (MS Windows),
\fBclassic\fR (Mac OS Classic), or \fBaqua\fR (Mac OS X Aqua).

254
255	.SH DESCRIPTION
256	.PP
257	The \fBtk\fR command provides access to miscellaneous
258	elements of Tk's internal state.
259	Most of the information manipulated by this command pertains to the
260	application as a whole, or to a screen or display, rather than to a
261	particular window.
262	The command can take any of a number of different forms
263	depending on the \fIoption\fR argument. The legal forms are:
264	.TP
265	\fBtk appname \fR?\fInewName\fR?
266	If \fInewName\fR isn't specified, this command returns the name
267	of the application (the name that may be used in \fBsend\fR
268	commands to communicate with the application).
269	If \fInewName\fR is specified, then the name of the application
270	is changed to \fInewName\fR.
271	If the given name is already in use, then a suffix of the form
272	``\fB #2\fR'' or ``\fB #3\fR'' is appended in order to make the name unique.
273	The command's result is the name actually chosen.
274	\fInewName\fR should not start with a capital letter.
275	This will interfere with option processing, since names starting with
276	capitals are assumed to be classes; as a result, Tk may not
277	be able to find some options for the application.
278	If sends have been disabled by deleting the \fBsend\fR command,
279	this command will reenable them and recreate the \fBsend\fR
280	command.

285	Sets and queries the caret location for the display of the specified

287	used for indicating global focus (e.g. to comply with Microsoft

289	XIM (X Input Methods) or Windows IME windows. If no options are specified,
290	the last values used for setting the caret are return in option-value pair
291	format. \fI\-x\fR and \fI\-y\fR represent window-relative coordinates, and
292	\fI\-height\fR is the height of the current cursor location, or the height
293	of the specified \fIwindow\fR if none is given.

298	Sets and queries the current scaling factor used by Tk to convert between
299	physical units (for example, points, inches, or millimeters) and pixels. The
300	\fInumber\fR argument is a floating point number that specifies the number of
301	pixels per point on \fIwindow\fR's display. If the \fIwindow\fR argument is
302	omitted, it defaults to the main window. If the \fInumber\fR argument is
303	omitted, the current value of the scaling factor is returned.

306	A ``point'' is a unit of measurement equal to 1/72 inch. A scaling factor
307	of 1.0 corresponds to 1 pixel per point, which is equivalent to a standard
308	72 dpi monitor. A scaling factor of 1.25 would mean 1.25 pixels per point,
309	which is the setting for a 90 dpi monitor; setting the scaling factor to
310	1.25 on a 72 dpi monitor would cause everything in the application to be
311	displayed 1.25 times as large as normal. The initial value for the scaling
312	factor is set when the application starts, based on properties of the
313	installed monitor, but it can be changed at any time. Measurements made
314	after the scaling factor is changed will use the new scaling factor, but it
315	is undefined whether existing widgets will resize themselves dynamically to
316	accomodate the new scaling factor.

321	.
322	Sets and queries the state of whether Tk should use XIM (X Input Methods)
323	for filtering events. The resulting state is returned. XIM is used in
324	some locales (ie: Japanese, Korean), to handle special input devices. This
325	feature is only significant on X. If XIM support is not available, this
326	will always return 0. If the \fIwindow\fR argument is omitted, it defaults
327	to the main window. If the \fIboolean\fR argument is omitted, the current
328	state is returned. This is turned on by default for the main display.
