Tk_SetGrid, Tk_UnsetGrid — control the grid for interactive
resizing
#include <tk.h>
Tk_SetGrid(tkwin, reqWidth, reqHeight, widthInc,
heightInc)
Tk_UnsetGrid(tkwin)
- 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.
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.
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.
