hi,
there is a little example of code. (I use gtkglext)
but how to connect the root group with the drawing area??
thanks.

gboolean init(GtkWidget widget, gpointer data){
GdkGLContext * context = gtk_widget_get_gl_context(GTK_WIDGET(drawing_area));
GdkGLDrawable * surface = gtk_widget_get_gl_drawable(GTK_WIDGET(drawing_area));
/* activation du contexte */
if(gdk_gl_drawable_gl_begin(surface,context))
{
/* dessin OpenGL */
gdk_gl_drawable_swap_buffers(surface); /* permutation des tampons */
gdk_gl_drawable_gl_end(surface); /* désactivation du contexte */
}
return TRUE;
}
int main (int argc, char **argv)
{
osg::Group* root = new osg::Group();
osg::Geode* pyramidGeode = createPyramid();
root->addChild(pyramidGeode);
GladeXML *xml;
gtk_init(&argc, &argv);
glade_init();
xml = glade_xml_new("../ConfigFile/WindowsView.glade", "window1", NULL);
if (!xml) {
g_warning("problem while loading the .glade file");
return 1;
}
GtkWidget *window1 = glade_xml_get_widget (xml, "window1");
drawing_area = glade_xml_get_widget(xml, "drawingarea1");
g_signal_connect(G_OBJECT(drawing_area),"realize",
G_CALLBACK(init),NULL);
GdkGLConfig * config;
config = gdk_gl_config_new_by_mode (static_cast<GdkGLConfigMode>
(GDK_GL_MODE_RGB |
GDK_GL_MODE_DEPTH |
GDK_GL_MODE_DOUBLE) );
GdkGLContext * context;
context = gtk_widget_get_gl_context(GTK_WIDGET(drawing_area));
gtk_widget_set_gl_capability(GTK_WIDGET(drawing_area), config,
context, TRUE, GDK_GL_RGBA_TYPE);
gtk_widget_show (window1);
gtk_main();
return 0;
}

sorry , but, not of them have gtk window ?? I don't understand all
could you be more precisely. THe only thing I try to do is connect a
pyramid osg in a gtkdrawingarea (constructed with glade)
