Problem with CEGUI integration - what's missing?

[cybersphinx]

Hello there,

I am currently trying to integrate CEGUI into an existing project. I started with the OpenGL/SDL example in the wiki, which I can run flawlessly. Then I tried to integrate that into my code. For simplicity, I just took the function drawing the menu and added the CEGUI calls to that.

The code looks like this:

Code: Select all

#include <CEGUI/CEGUI.h>
#include <CEGUI/renderers/OpenGLGUIRenderer/openglrenderer.h>

int cegui_initialized = 0;
static CEGUI::OpenGLRenderer* ce_renderer;
static CEGUI::Window* ce_window;
static double last_time_pulse;

void runmenu(void) {
   if (!cegui_initialized) {
      ce_renderer = new CEGUI::OpenGLRenderer(0);
      new CEGUI::System(ce_renderer);
      CEGUI::Logger::getSingleton().setLoggingLevel(CEGUI::Insane);
      CEGUI::SchemeManager::getSingleton().loadScheme("../datafiles/schemes/TaharezLook.scheme");
      CEGUI::FontManager::getSingleton().createFont("../datafiles/fonts/Commonwealth-10.font");
      CEGUI::System::getSingleton().setDefaultFont("Commonwealth-10");
      CEGUI::System::getSingleton().setDefaultMouseCursor("TaharezLook", "MouseArrow");
      ce_window = CEGUI::WindowManager::getSingleton().loadWindowLayout("../datafiles/test.layout");
      CEGUI::System::getSingleton().setGUISheet(ce_window);

      last_time_pulse = 0.001 * static_cast<double>(SDL_GetTicks());

      cegui_initialized = 1;
   }

// do old menu stuff

   {
      double t = 0.001 * SDL_GetTicks();
      CEGUI::System::getSingleton().injectTimePulse(float(t - last_time_pulse));
      last_time_pulse = t;
   }

// draw old menu

   CEGUI::System::getSingleton().renderGUI();
}


Everything loads OK, the old menu works as before, but CEGUI just doesn't show anything. Are there some OpenGL states that have to be set for CEGUI to work in addition to those in the initPerFrameStates method? Or what else could it be?

Hello again,

Seems like a difficult problem, or perhaps the subject line was misleading - I've changed it now. Well, anyway, I still haven't found a solution, so I'd appreciate any clues.

sounds a bit strange, as your code looks ok.
you may want to try getting the v0-4 branch from CVS as it contains some (pretty serious) bugfixes to the openglrenderer.

Hm, I did that (rebuilt the Debian package with the source from 'cvs co -rv0_4'), but it still doesn't work.

I guess there's something in OpenGL set in a way CEGUI doesn't expect, but I have no clue what...
