The color changing part works fine but if i use some kind of
delay the program just starts delayed but no color changing
happens. I am wondering why, because everything is executed in
one thread, so the execution order looks like this to me:
1. Start GUI
2. Change Button Color to flash color
3. Wait 2 sec
4. Change Button Color back to standard
Everything in GTK runs in the same thread, if your delay is a
blocking one (i.e. putting the thread to sleep for 2 seconds)
none of the GTK events will fire to redraw the button since the
thread is occupied with your delay.
I hope i can get around it without getting into multithreading?
Other then the obvious multi-threaded, using glib.Timeout to
trigger the reversion of the color change could be an option.
