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 typi-
       cally 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 informa-
       tion.

       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.
