NAME
       Tk_SetGrid, Tk_UnsetGrid - control the grid for interactive 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_GeometryRequest.

       int	   reqHeight   (in)	 Height in grid units that corresponds
					 to  the  pixel	 dimension  tkwin  has
					 requested via Tk_GeometryRequest.

       int	   widthInc    (in)	 Width of one grid unit, in pixels.

       int	   heightInc   (in)	 Height of one grid unit, in pixels.

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 allo-
       cated 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.

       For  each toplevel window there can be at most one internal window with
       gridding enabled.  If Tk_SetGrid or Tk_UnsetGrid is invoked  when  some
       other  window is already controlling 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.
