OpenGLRenderer - rendering offset and cut off [SOLVED]
Posted: Thu Mar 04, 2010 10:00
Hey folks, new user here.
I'm trying to integrate CEGUI with a school project, and I'm having a bit of trouble with the OpenGLRenderer. I set up the basic GL renderer and simple window as outlined in the beginner docs. I kinda banged my head against the desk a few times trying to figure out why CEGUI's mouse coordinates did not correspond to the coordinates GLUT was giving me for the mouse. Fortunately, I found the OpenGLRenderer::setDisplaySize() method and am now calling it before trying to render anything. That worked fine (this method may be worth a mention in the new user docs, actually). However, I now have a new problem. The renderer does not seem to want to render outside of an 800x600 box... I have linked the log and two images (1, 2) detailing the problem a bit more (these links may be dead in a few months, sorry. No attachments on this forum?). The actual window size can be read from the terminal on the right (format: DS: <width> <height>).
Any clue? Here is the code for my entire CEGUI renderer. It's a custom framework over GLUT, but it should be pretty obvious what method does what.
Thanks guys!
