 int count = 1 ;
 XTextProperty text ;
 list[0] = title ; 
.......
.......
 if( XStringListToTextProperty( list, count, &text ) )
 {
 xwin = GDK_WINDOW_XWINDOW( GTK_WIDGET( window )->window ) ;    
 XSetWMName( GDK_DISPLAY( ), xwin, &text ) ;
 }
 if( screen == 1 )
 ParentWindow = xwin ;
 if( screen == 2 )
 XReparentWindow( GDK_DISPLAY( ), xwin, ParentWindow, 1, 1 ) ;
