Hi!
I know, this may be a bit off topic. But I've a dificulty:
I'm currently programming a textbase "GUI"-lib. I want the programming
API
to be similar to on of a real GUI-lib (gtk, you name them).
Now I'm wondering, there are menus. Menus have menuitems and if you click
on
one, something should happen. How is this "something should happen" part
usually done?
It's done by registering a call back. In current gtk versions this is
done by having actions and they have a label and are associated with a
particular function. Using the python bindings
http://www.pygtk.org/pygtk2tutorial/sec-UIManager.html explains the
general idea for menus. There is an example there. All buttons etc in
gtk work the same i.e with call backs being registered.
