creating a custom button in GTK--

[Akos Maroy <darkeye tyrell hu>]

Hi,

A newbie question here: I'd like to create a custom button in GTK--. I 
subclassed Gtk::Bin, which would contain the only child, shown inside 
the button. I can draw the border of my button in the overrideen 
on_expose_event() function. But what I can't do is to influence where 
the child widget is drawn when calling Bin::on_expose_event() from 
within the overriden on_expose_event().

I tried to override on_size_allocate, calculate the space available for 
the child widget there (which is the size of my button, minus the size 
of the borders which display it as a button). and then call 
get_child()->size_allocate() with the calculated size - but this does 
not have the desired effect.
