'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" .AP type name in/out ?indent?
'\" Start paragraph describing an argument to a library procedure.
'\" type is type of argument (int, etc.), in/out is either "in", "out",
'\" or "in/out" to describe whether procedure reads or modifies arg,
'\" and indent is equivalent to second arg of .IP (shouldn't ever be
'\" needed; use .AS below instead)
'\" Give maximum sizes of arguments for setting tab stops. Type and
'\" name are examples of largest possible arguments that will be passed
'\" to .AP later. If args are omitted, default tab stops are used.
'\" Start box enclosure. From here until next .BE, everything will be
'\" enclosed in one large box.
'\" End of box enclosure.
'\" Begin vertical sidebar, for use in marking newly-changed parts
'\" of man pages. The first argument is ignored and used for recording
'\" the version when the .VS was added, so that the sidebars can be
'\" found and removed when they reach a certain age. If another argument
'\" is present, then a line break is forced before starting the sidebar.
'\" End of vertical sidebar.
'\" Begin an indented unfilled display.
'\" End of indented unfilled display.
'\" Start of list of standard options for a Tk widget. The
'\" options follow on successive lines, in four columns separated
'\" End of list of standard options for a Tk widget.
'\" .OP cmdName dbName dbClass
'\" Start of description of a specific option. cmdName gives the
'\" option's name as specified in the class command, dbName gives
'\" the option's name in the option database, and dbClass gives
'\" the option's class in the option database.
'\" Print arg1 underlined, then print arg2 normally.

Tk_SetGrid, Tk_UnsetGrid \- control the grid for interactive resizing
\fBTk_SetGrid\fR(\fItkwin, reqWidth, reqHeight, widthInc, heightInc\fR)
\fBTk_UnsetGrid\fR(\fItkwin\fR)
Width in grid units that corresponds to the pixel dimension \fItkwin\fR
has requested via \fBTk_GeometryRequest\fR.
Height in grid units that corresponds to the pixel dimension \fItkwin\fR
has requested via \fBTk_GeometryRequest\fR.
Width of one grid unit, in pixels.
Height of one grid unit, in pixels.
\fBTk_SetGrid\fR turns on gridded geometry management for \fItkwin\fR's
toplevel window and specifies the geometry of the grid.
\fBTk_SetGrid\fR is typically invoked by a widget when its \fBsetGrid\fR
It restricts interactive resizing of \fItkwin\fR's toplevel window so
that the space allocated to the toplevel is equal to its requested
size plus or minus even multiples of \fIwidthInc\fR and \fIheightInc\fR.
Furthermore, the \fIreqWidth\fR and \fIreqHeight\fR values are
passed to the window manager so that it can report the window's
size in grid units during interactive resizes.
If \fItkwin\fR's configuration changes (e.g., the size of a grid unit
changes) then the widget should invoke \fBTk_SetGrid\fR again with the new
\fBTk_UnsetGrid\fR cancels gridded geometry management for
\fItkwin\fR's toplevel window.
For each toplevel window there can be at most one internal window
If \fBTk_SetGrid\fR or \fBTk_UnsetGrid\fR is invoked when some
other window is already controlling gridding for \fItkwin\fR's
toplevel, the calls for the new window have no effect.
See the \fBwm\fR manual entry for additional information on gridded geometry
