- Tk_Window tkwin (in)
Token for window. - Visual *visual (in)

DESCRIPTION
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 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 Tk_SetWindowColormap instead.
