In my lowly iBook, it has support for an OpenGL window as large as you like, even larger than the desktop, but it does not have support for full-screen mode by the hardware. The OpenGL driver is software only and cannot apparently handle proper fullscreen.
When trying to open a screen in full-screen mode, it just simply doesn't open and Max complains about invalid pixel format and some other such. Basically it makes an error because it can't do it.
That's fine. I want to be able to detect when this error occurs, however, so that if my app tries to open a full-screen display and fails, it will automatically try opening in a window. I would also like to sense when window mode fails so I can try opening fullscreen, on platforms that have fullscreen support.
I tried using something like:
Try
Context=CreateGraphics(640,480,32,60,GRAPHICS_BACKBUFFER)
Catch err:Object
Context=CreateGraphics(640,480,0,60,GRAPHICS_BACKBUFFER)
EndTry
But this does not actually catch the exception. The context fails to open and the app exits with the usual error message.
How can I detect this failure to open a context, and still remain in the running app so I can try a different angle?
