Hi Jim, Thanx a lot for your reply. Well, right now I am planning to do that by using a gtk.notebook without tabs and borders, though I would be firstly testing how it would look. The idea you suggests seems to be good and I had a look at the screen shots, they really look nice. In case the notebook thing doesn't give me the desired looks, will be switching over to this idea.

Another option you have, not necessarily better, is to define a VBox holding the two different views of your Activity: the one where the game is played and the one where you set up options. By hiding one and showing the other you can switch from one view to the other. I do something like this in all three of my Activities (Read Etexts, View Slides, Get Internet Archive Books) where I divide the screen vertically in half for some functions. See the screenshots on ASLO to see what I'm talking about. I like how this works and looks. Your mileage may vary. James Simmons </blockquote></div>
