composite widget and custom draw with cairo

[Tommi Sakari Uimonen <tuimonen cc hut fi>]

Hello.

I managed to modify the tictactoe example so that I could draw on top of 
the 3x3 button grid with cairo. I followed the tutorial of creating custom 
widgets and added expose event to the tictactoe.

But when I replaced the buttons with my own custom widgets based on 
GtkDrawingArea, the tictactoe's expose even was not called anymore.

My custom widget uses cairo also and has its own expose event.

I need to draw on top of the custom child widgets. Any Ideas what could be 
the problem?
