[maemo-developers] simple gtk themed button example?

[From: Zac Filan]

Hello,

Can someone point me to a C code example of a gtk button that responds
to system theme changes?

I have a N810, when I change the system theme the  buttons on the
internet radio applet (for example) change to suite the theme. I would
like to know how to write a Gtk application (not an applet ) where the
buttons in my application also change with the theme.

e.g. something like step 5 here:
http://maemo.org/development/documentation/tutorials/maemo_4-0_tutorial.html#gui
but that is theme aware.

Thanks!
Zac
