Re: Customizing scrollbar in a ScrolledWindow

[siagogam <siagogam terra es>]

Hi Chuck:

I can derive the Gtk::Scrollbar class with my new class, thats not the
problem. The problem is that internally the Gtk::ScrolledWindow instanciates
two Gtk::ScrollBars when is created (really is the gtk_scrolled_window the
one that creates the scrollbars), and I cant see the way of replacing those
Gtk::ScrollBars instances with my own class (MyCoolScrollbar) instances. So
the expose, size.. methods that will be used inside the SrolledWindow wont
be my overloaded methods.

Please tell me if I am wrong.

thanks
