[maemo-developers] [maemo-developers] gtkmm and scratchbox: Gtk::DrawingArea problem (drawings not showing)

[From: Jarkko Palviainen]

Hi,
I'm trying to build simple drawing app for Nokia 770 IT2006 but here's the  
problem:
When compiling and running some example, like this
http://www.gtkmm.org/gtkmm2/docs/tutorial/html/ch14s03.html#id2524813
it goes well but just doesn't draw anything on Xephyr emulator, just blank  
window. Compiling and running in normal Debian Sarge is fine, I can see  
those lines drawn. The problem seems to be related to on_expose_event()  
which is not called as I testes by debug printing in it. I can't use cairo  
as I have to use glibmm 2.8.9. (Can't find any cairo libs in maemo repos  
either?)

I can load and display and png image and run hello world gtkmm apps in  
sbox, so it seems to be working, but I'm really stuck with the drawing and  
I need to draw dots or circles on the image (a map) I'm showing. Any  
suggestions? I'm new to gtk+ and gtkmm so if any questions please ask.
