10 '\" The definitions below are for supplemental macros used in Tcl/Tk
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)
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.
26 '\" Start box enclosure. From here until next .BE, everything will be
27 '\" enclosed in one large box.
30 '\" End of box enclosure.
33 '\" Begin code excerpt.
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.
46 '\" End of vertical sidebar.
49 '\" Begin an indented unfilled display.
52 '\" End of indented unfilled display.
55 '\" Start of list of standard options for a Tk widget. The
56 '\" options follow on successive lines, in four columns separated
60 '\" End of list of standard options for a Tk widget.
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.
69 '\" Print arg1 underlined, then print arg2 normally.

266 has requested via \fBTk_GeometryRequest\fR.
268 Width of one grid unit, in pixels.
270 Height of one grid unit, in pixels.
275 \fBTk_SetGrid\fR turns on gridded geometry management for \fItkwin\fR's
276 toplevel window and specifies the geometry of the grid.
277 \fBTk_SetGrid\fR is typically invoked by a widget when its \fBsetGrid\fR
279 It restricts interactive resizing of \fItkwin\fR's toplevel window so
280 that the space allocated to the toplevel is equal to its requested
281 size plus or minus even multiples of \fIwidthInc\fR and \fIheightInc\fR.
282 Furthermore, the \fIreqWidth\fR and \fIreqHeight\fR values are
283 passed to the window manager so that it can report the window's
284 size in grid units during interactive resizes.
285 If \fItkwin\fR's configuration changes (e.g., the size of a grid unit
286 changes) then the widget should invoke \fBTk_SetGrid\fR again with the new
289 \fBTk_UnsetGrid\fR cancels gridded geometry management for
290 \fItkwin\fR's toplevel window.
292 For each toplevel window there can be at most one internal window
293 with gridding enabled.
294 If \fBTk_SetGrid\fR or \fBTk_UnsetGrid\fR is invoked when some
295 other window is already controlling gridding for \fItkwin\fR's
296 toplevel, the calls for the new window have no effect.
