Gtk buttons over a Gtk drawing area

问题:

i' working with Gtk developing some app. I must put some buttons over a map. I'm drawing the map on a GtkDrawingarea, but i'm not able to put buttons over it. Any suggestion? Thanks

Suggestions:

1. Put both the drawing area and the buttons inside a GtkFixed container. Probably not the best solution, because GtkFixed has no way of controlling the z-ordering (other than the order in which you add the widgets to it?)
2. Instead of using GtkDrawingArea, use a canvas widget that can include other widgets, such as GooCanvas.

Why no other library? Any specific reason?

There is a library for exactly what you want
