    No surprise there.

    Neither. You must explicitly call them in your Expose Event handler.
    In X (and, consequently, in XForms) making a draw call isn't like
    creating a member of a display list or scene graph node which gets
    automagically traversed whenever an Expose Event occurs. The only
    thing that happens is that the event is handed off to a registered
    event handler which is supplied by the applicatioin and it is the
    application's responsibility to do whatever drawing or redrawing might
    be necessary.
