-    Your widget needs an OpenGL capable visual and you also need to set
-    a colormap for it. The widget must also have an X window (not all
-    widgets have it).

 DESCRIPTION
        Make an OpenGL widget, attrList is passed to glXChooseVisual
        GLX call. See glXChooseVisual man page for explanation of
-       attrList. Widget is created with visual and colormap of the
+       attrList. Widget is created with visual of the
        requested type and GLX context is created for this widget. You
        can't do opengl calls on widget until it has X window. X window
        is not created until widget is realized.
