RE: [gtkmm] Custom widget example

["Roel Vanhout" <rvanhout riks nl>]

The Ardour people (www.ardour.org) have written some custom widgets with
gtkmm. I was pointed to that project when I asked about custom widgets
on this list (although I cannot find my own message any more). For
example, take a look at
http://ardour.org/cgi-bin/viewcvs.cgi/ardour/gtk_ardour/gain_pan_meter.h
?rev=1.18&content-type=text/vnd.viewcvs-markup, that's a class that
subclasses Gtk::Vbox and implements its own drawing. Maybe it can give
you some hints.


cheers,

roel

Thanks, but that does not seem to make a difference.
