I am using gtk_scrolled_window_add_with_viewport() to get scrolling capabilities for a drawing area. In my program, I am drawing to a backing pixmap which I in turn draw onto the drawing area with an expose event handler. The problem I am having is that even though the pixmap is larger than the drawing area, the drawing area does not scroll. If however, I use gtk_set_size_request() on the drawing area to increase its dimensions, the drawing area scrolls. Any suggestions on what I could be doing wrong? Thanks.
