Tk_SetWindowVisual - change visual characteristics of window
Tk_SetWindowVisual(tkwin, visual, depth, colormap)
When Tk creates a new window it assigns it the default visual
characteristics (visual, depth, and colormap) for its screen.
Tk_SetWindowVisual may be called to change them.
Tk_SetWindowVisual must be called before the window has
actually been created in X (e.g. before Tk_MapWindow or
Tk_MakeWindowExist has been invoked for the window).
The safest thing is to call Tk_SetWindowVisual immediately
after calling Tk_CreateWindow.
If tkwin has already been created before Tk_SetWindowVisual
is called then it returns 0 and doesn't make any changes; otherwise
it returns 1 to signify that the operation
- Tk_Window tkwin (in)
Token for window.
- Visual *visual (in)
New visual type to use for tkwin.
- int depth (in)
Number of bits per pixel desired for tkwin.
- Colormap colormap (in)
New colormap for tkwin, which must be compatible with
visual and depth.
Note: Tk_SetWindowVisual should not be called if you just want
to change a window's colormap without changing its visual or depth;
call Tk_SetWindowColormap instead.
