Hi there,
I'm new with Gtkmm and GtkGlExtmm. I'm trying to put the "gears" example
not into a Gtk::Window but into a Gtk::Frame (which is into a
Gtk::Table) and it doesn't work.
Glib::RefPtr<Gdk::GL::Config> glconfig;
// Try double-buffered visual
glconfig = Gdk::GL::Config::create(Gdk::GL::MODE_RGB |
Gdk::GL::MODE_DEPTH |
Gdk::GL::MODE_DOUBLE);
if (!glconfig)
{
std::cerr << "*** Cannot find the double-buffered visual.\n"
<< "*** Trying single-buffered visual.\n";
// Try single-buffered visual
glconfig = Gdk::GL::Config::create(Gdk::GL::MODE_RGB |
Gdk::GL::MODE_DEPTH);
if (!glconfig)
{
std::cerr << "*** Cannot find any OpenGL-capable visual.\n";
std::exit(1);
}
}
In fact, it doesn't succeed to create the glconfig objet.
Any idea to solve this problem?
Mick
