I agree, this can be tricky with an asynchronous toolkit. In my opinion, the best solution is to do the scrolling from the expose event. When you create the new object, set a flag on it called This does not work, as I described in my original message: Changing the adjustment in the handler of the exposure event does also not work reliably. Sometimes the DrawingArea receives exposure events before the size has changed. I guess that the exposure event before changing the size is caused by my call to gtk_widget_queue_draw. I have to do this because adding a new element might change positions of old elements and I therefore have to redraw everything. I don't understand why there is an exposure event before the size request has been dealt with. When the size changes, it is likely that additional exposure events are necessary. Therefore it would be better to postpone the exposure events until the size has changed. Is there any way to force the size allocation after I have called gtk_widget_set_size_request?
