std::cout.flush();
Glib::RefPtr<Gdk::GL::Config> glconfig;

Gdk::GL::MODE_DOUBLE);
if(!glconfig)
{
Gtk::MessageDialog e("Couldn't find OpenGL visual.\nPlease

e.run();
}
if(!set_gl_capability(glconfig) || !is_gl_capable())
{
Gtk::MessageDialog e("Couldn't set OpenGL capability.\nPlease
ensure
that OpenGL drivers are installed correctly.", Gtk::MESSAGE_ERROR);
e.run();
}
}
When I try to call the base constructor I get the following runtime error:
(ttedit:12863): GtkGLExt-CRITICAL **: gtk_widget_set_gl_capability:
assertion `!GTK_WIDGET_REALIZED (widget)' failed
and on_realize() isn't called.
It seems the derived widget is not used at all: When I change
Display *display = 0;
refXml->get_widget_derived("display", display);
Gtk::Window* main_win = 0;
refXml->get_widget("main_window", main_win);
if (main_win)
{
kit.run(*main_win);
}
return 0;
}
to
Gtk::Window* main_win = 0;
refXml->get_widget("main_window", main_win);
if (main_win)
{
kit.run(*main_win);
}
return 0;
}
in main the result looks the same. So it seems the get_widget_derived()
just creates a widget, but I haven't found out yet how to make
glademm/gtkmm/libglademm/whatever use it.
