NAME

Tk_SetWindowVisual - change visual characteristics of window  

SYNOPSIS

#include <tk.h>

int
Tk_SetWindowVisual(tkwin, visual, depth, colormap)
 

ARGUMENTS

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)

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.
