[maemo-developers] How can I change the background color of a GtkButton when it is activated

[From: Andrew Olmsted]

What about connecting two signals to your button widget: pressed and
released
In the function for "pressed" change the background colour to blue.

In the function for "released" change the background colour back to normal.

http://library.gnome.org/devel/gtk/stable/GtkButton.html#GtkButton.signals

I think this should do what you want, though I don't know if it is the
optimal way.
