  10 '\" The definitions below are for supplemental macros used in Tcl/Tk
  11 '\" manual entries.
  12 '\"
  13 '\" .AP type name in/out ?indent?
  14 '\"     Start paragraph describing an argument to a library procedure.
  15 '\"     type is type of argument (int, etc.), in/out is either "in", "out",
  16 '\"     or "in/out" to describe whether procedure reads or modifies arg,
  17 '\"     and indent is equivalent to second arg of .IP (shouldn't ever be
  18 '\"     needed;  use .AS below instead)
  19 '\"
  20 '\" .AS ?type? ?name?
  21 '\"     Give maximum sizes of arguments for setting tab stops.  Type and
  22 '\"     name are examples of largest possible arguments that will be passed
  23 '\"     to .AP later.  If args are omitted, default tab stops are used.
  24 '\"
  25 '\" .BS
  26 '\"     Start box enclosure.  From here until next .BE, everything will be
  27 '\"     enclosed in one large box.
  28 '\"
  29 '\" .BE
  30 '\"     End of box enclosure.

  32 '\" .CS
  33 '\"     Begin code excerpt.
  34 '\"
  35 '\" .CE
  36 '\"     End code excerpt.
  37 '\"
  38 '\" .VS ?version? ?br?
  39 '\"     Begin vertical sidebar, for use in marking newly-changed parts
  40 '\"     of man pages.  The first argument is ignored and used for recording
  41 '\"     the version when the .VS was added, so that the sidebars can be
  42 '\"     found and removed when they reach a certain age.  If another argument
  43 '\"     is present, then a line break is forced before starting the sidebar.
  44 '\"
  45 '\" .VE
  46 '\"     End of vertical sidebar.
  47 '\"
  48 '\" .DS
  49 '\"     Begin an indented unfilled display.
  50 '\"
  51 '\" .DE
  52 '\"     End of indented unfilled display.
  53 '\"
  54 '\" .SO
  55 '\"     Start of list of standard options for a Tk widget.  The
  56 '\"     options follow on successive lines, in four columns separated
  57 '\"     by tabs.
  58 '\"
  59 '\" .SE
  60 '\"     End of list of standard options for a Tk widget.
  61 '\"
  62 '\" .OP cmdName dbName dbClass
  63 '\"     Start of description of a specific option.  cmdName gives the
  64 '\"     option's name as specified in the class command, dbName gives
  65 '\"     the option's name in the option database, and dbClass gives
  66 '\"     the option's class in the option database.
  67 '\"
  68 '\" .UL arg1 arg2
  69 '\"     Print arg1 underlined, then print arg2 normally.

 249 .SH NAME
 250 tk \- Manipulate Tk internal state
 251 .SH SYNOPSIS
 252 \fBtk\fR \fIoption \fR?\fIarg arg ...\fR?
 253 .BE
 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.
 281 .TP
 282 \fBtk scaling \fR?\fB\-displayof \fIwindow\fR? ?\fInumber\fR?
 283 .
 284 Sets and queries the current scaling factor used by Tk to convert between
 285 physical units (for example, points, inches, or millimeters) and pixels.  The
 286 \fInumber\fR argument is a floating point number that specifies the number of
 287 pixels per point on \fIwindow\fR's display.  If the \fIwindow\fR argument is
 288 omitted, it defaults to the main window.  If the \fInumber\fR argument is
 289 omitted, the current value of the scaling factor is returned.
 290 .RS
 291 .PP
 292 A ``point'' is a unit of measurement equal to 1/72 inch.  A scaling factor
 293 of 1.0 corresponds to 1 pixel per point, which is equivalent to a standard
 294 72 dpi monitor.  A scaling factor of 1.25 would mean 1.25 pixels per point,
 295 which is the setting for a 90 dpi monitor; setting the scaling factor to
 296 1.25 on a 72 dpi monitor would cause everything in the application to be
 297 displayed 1.25 times as large as normal.  The initial value for the scaling
 298 factor is set when the application starts, based on properties of the
 299 installed monitor, but it can be changed at any time.  Measurements made
 300 after the scaling factor is changed will use the new scaling factor, but it
 301 is undefined whether existing widgets will resize themselves dynamically to
 302 accomodate the new scaling factor.
 303 .RE
 304 .VS 8.3
 305 .TP
 306 \fBtk useinputmethods \fR?\fB\-displayof \fIwindow\fR? ?\fIboolean\fR?
 307 .
 308 Sets and queries the state of whether Tk should use XIM (X Input Methods)
 309 for filtering events.  The resulting state is returned.  XIM is used in
 310 some locales (ie: Japanese, Korean), to handle special input devices.  This
 311 feature is only significant on X.  If XIM support is not available, this
 312 will always return 0.  If the \fIwindow\fR argument is omitted, it defaults
 313 to the main window.  If the \fIboolean\fR argument is omitted, the current
 314 state is returned.  This is turned on by default for the main display.
