NAME
Tk_SetGrid, Tk_UnsetGrid - control the grid for interac
tive resizing
SYNOPSIS
#include <tk.h>
Tk_SetGrid(tkwin, reqWidth, reqHeight, widthInc, heightInc)
Tk_UnsetGrid(tkwin)
ARGUMENTS
Tk_Window tkwin (in) Token for window.
int reqWidth (in) Width in grid units that
corresponds to the pixel
dimension tkwin has
requested via Tk_Geome
tryRequest.
int reqHeight (in) Height in grid units
that corresponds to the
pixel dimension tkwin
has requested via

DESCRIPTION
Tk_SetGrid turns on gridded geometry management for
tkwin's toplevel window and specifies the geometry of the
grid. Tk_SetGrid is typically invoked by a widget when
its setGrid option is true. It restricts interactive
resizing of tkwin's toplevel window so that the space
allocated to the toplevel is equal to its requested size
plus or minus even multiples of widthInc and heightInc.
Furthermore, the reqWidth and reqHeight values are passed
to the window manager so that it can report the window's
size in grid units during interactive resizes. If tkwin's
configuration changes (e.g., the size of a grid unit
changes) then the widget should invoke Tk_SetGrid again
with the new information.
Tk_UnsetGrid cancels gridded geometry management for
tkwin's toplevel window.
window with gridding enabled. If Tk_SetGrid or Tk_Unset
Grid is invoked when some other window is already control
ling gridding for tkwin's toplevel, the calls for the new
window have no effect.
See the wm manual entry for additional information on
gridded geometry management.
