Tk_SetWindowVisual - change visual characteristics of window
Tk_SetWindowVisual(tkwin, visual, depth, colormap)
- 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
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 does not make any
changes; otherwise it returns 1 to signify that the operation completed
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.
