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 and depth.
When Tk creates a new window it assigns it the default visual characteristics (visual, depth, and colormap) for its screen. Tk_SetWin-
dowVisual 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 successfully.
Note: Tk_SetWindowVisual should not be called if you just want to change a window's colormap without changing its visual or depth; call
colormap, depth, visual
