Hi,
I'm trying to use GTK+ 2.0 for my GUI, but I'm not sure how I could implement a menu that slides out when a button is clicked. Making a menu disappear/re-appear instantaneously would not be difficult to do as it requires a simple change to the visibility property. This app is being developed on Windows, but I'm also planning to port it over to Linux. So any ideas on how to achieve menu transitions that work on Windows and Linux?
