 Dear axora, I would love to read you messages but I cant because they were all sent in html mail. I would be very grateful if you could resend them without the html noise :(. Thank you very much!

First, before performing any context reference operations, the GL widget should be +realized+ to manipulate any references inside. I have included some source code that I use in one of my apps to enlighten. with typecasts to make it easier to associate types: // Get OpenGL rendering context. gtk_widget_realize ((GtkWidget *) yourGLCapableWidget); (GdkGLContext *) theSharedGlContext = gtk_widget_get_gl_context ((GtkWidget *) yourGLCapableWidget); // Initialise the other GL areas with the same shared context. (GtkWidget *) anotherGLWidget = GTK_WIDGET (gtk_builder_get_object (yourGTKBuilderXml, "GLwidget2")); // Add OpenGL-capability to the other widget, sharing the same context. gtk_widget_set_gl_capability ((GtkWidget *) anotherGLWidget, glConfig, (GdkGLContext *) theSharedGlContext, TRUE, GDK_GL_RGBA_TYPE); ... etc Note that 'gtk_widget_realize' is essential for the following functions to reference data within. Another caveat is that some drivers align texture data, depending on hardware - after the storage->framebuffer phase the alignment can vary if the hardware is not capable of non-powers-of-two textures. You may find that the driver will texture-split any non-power-of-two rectangles. The solution to this is to make sure that if the driver/hardware does not support non-power-of-two textures, to use the stride value in retrieving data back from the framebuffer. Regards, Jose.

In your code you have this: gboolean reshapeGL(GtkWidget *widget, GdkEventConfigure *evnt, gpointer data) { GUIWindow* me = (GUIWindow*)data; There's a quirk in using the 'gpointer data' object in a GTK function - it actually gets swapped in the stack if you do so, and is *not recommended* :P. The best approach is to not use the 'gpointer data' at all; instead, if you want to pass your user data to a GTK function, attach a GObject to it like so - in this example I am attaching it to the window containing the GL context: (-in place of setting the user data in your initialisation code-) g_object_set_data ((GObject *)theWindowWithYourGLContext, "myUserData", &theActualData); And then use something like this to retrieve it: gboolean reshapeGL(GtkWidget *widget, GdkEventConfigure *evnt, gpointer data) { GUIWindow* me = g_object_get_data ((GObject *)gtk_widget_get_toplevel (widget), "myUserData"))); In your reshape (and other) functions that need it.

Gtk::GL::init(argc, argv); // Query OpenGL extension version. int major, minor; Gdk::GL::query_version(major, minor); std::cout << "OpenGL extension version - "<< major << "." << minor << std::endl; GUIVentanaPrincipal gui; m.run(gui); return 0; } [/code] but glewinit fails to initialize this is my output [code] *GLEW Cannot Init *GLEW_ARB_vertex_buffer_object = NULL OpenGL extension version - 1.4 [/code] why this happens when using gtkglextmm and glew?, it only happens on this project im working. -- View this message in context: http://www.nabble.com/gtkglextmm-and-glewinit-simple-question-tp25455459p25455459.html Sent from the Gnome - GtkGLExt mailing list archive at Nabble.com.
