 .TH Tk_SetWindowVisual 3 4.0 Tk "Tk Library Procedures"

 .SH NAME
 Tk_SetWindowVisual \- change visual characteristics of window
 .SH SYNOPSIS
 .nf
 \fB#include <tk.h>\fR
 .sp
 int
 \fBTk_SetWindowVisual\fR(\fItkwin, visual, depth, colormap\fR)
 .SH ARGUMENTS
 .AS "Tk_Window int" colormap
 .AP Tk_Window tkwin in
 Token for window.
 .AP Visual *visual in
 New visual type to use for \fItkwin\fR.
 .AP "int" depth in
 Number of bits per pixel desired for \fItkwin\fR.
 .AP Colormap colormap in
 New colormap for \fItkwin\fR, which must be compatible with
 \fIvisual\fR and \fIdepth\fR.
 .BE

 .SH DESCRIPTION
 .PP
 When Tk creates a new window it assigns it the default visual
 characteristics (visual, depth, and colormap) for its screen.
 \fBTk_SetWindowVisual\fR may be called to change them.
 \fBTk_SetWindowVisual\fR must be called before the window has
 actually been created in X (e.g. before \fBTk_MapWindow\fR or
 \fBTk_MakeWindowExist\fR has been invoked for the window).
 The safest thing is to call \fBTk_SetWindowVisual\fR immediately
 after calling \fBTk_CreateWindow\fR.
 If \fItkwin\fR has already been created before \fBTk_SetWindowVisual\fR
 is called then it returns 0 and doesn't make any changes;  otherwise
 it returns 1 to signify that the operation
 completed successfully.
 .PP
 Note:  \fBTk_SetWindowVisual\fR should not be called if you just want
 to change a window's colormap without changing its visual or depth;
 call \fBTk_SetWindowColormap\fR instead.
