Since GTK is object oriented, you could just create a new class that
inherits from GtkCalender. However this is

As I think about it, my knowledge of extending GTK really is out of

Rereading your post I think you called this composite widget. I'm not
sure why you are opposed to this idea. I've created a composite widget
myself and it has worked great for me.

Right, thanks. Alright so using extend might not have been the right
term (probably comes because I've done some PHP and have been influenced
by that), sorry.
Oh, and I've used the term composite widget simply because I read it
here, and assumed it was how such widgets were called:

Precisely. Vala makes the C Gobjects. You could use Vala to construct
a class with a bunch of empty methods and then use the generated C code

Just for your information, here's a couple of examples of extending
GtkButton using inheritance and the GObject Builder tool:

As always, read the docs. Here is the documentation describing how to
create new GObjects, and inherit from existing ones, implement virtual

You really could Create a GtkMyButton by inheriting from GtkButton and

What I'm looking for is inheritance, and I see how it could be done yes.
However, that would require the original widget to be done using virtual

Alright, I think I'm starting to see things a little better now - thank
you all.
I believe, in the case of GtkCalendar, there are no virtual public
methods, only static/private ones, and most of them use other such
methods as well as the private structure, which is why creating a widget
