Hi Ron, > GCC complains thus: > /usr/include/gdkmm-2.4/gdkmm/gc.h:389: error: `Gdk::GC::GC()' is protected
That is because Gdk::GC does not have a public constructor. You must either use Gdk::GC::create() or some other function that returns a Glib::RefPtr<Gdk::GC>: Glib::RefPtr<Gdk::Window> window = get_window(); Glib::RefPtr<Gdk::GC> gc = Gdk::GC::create(window); This means Gdk::GC may only be accessed through a Glib::RefPtr. > The next line fails as well: > Gdk::Colormap appColormap(Gdk::Colormap::get_system()); Again, there is no public constructor for Gdk::Colormap. You have to use the Gdk::Colormap::create() or Gdk::Colormap::get_system() functions and assign the return value to a Glib::RefPtr<Gdk::Colormap>: Glib::RefPtr<Gdk::Colormap> appColormap = Gdk::Colormap::get_system(); > I'm completely confused.

Take a look at the reference documentation to see what you can do with the gtkmm objects. Gtk::DrawingArea is derived from Gtk::Window, so you can set the size with Gtk::Window::set_default_size(int width, int height) Cheers, Jörn _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
