Hello:
I keep a min widht and height for the scen graph in the GlWidget I
have. So when overriding the virtual method resizeGl(int width, int
height) I have something like:
if(width < minWidth) width = minWidth;
if(height < minHeight) height = minHeight;
// now set the viewport as normal
//
return;

What should I back up?
What's the possible variables that may cause this scenario? Please
give me
some clue so that I know what variable to watch in the debugging mode.
Thanks.

Hi,
I wonder if the viewport is being scaled to 0 width and no moving back
up, or perhaps the projection matrix is ending up at zero.
You haven't specified how you've integrated with the OSG so I don't
what to recommend.

I'm writing a test program with OSG in QT4 based windowing system.
Here's what I did:
I loaded a scene, it showed well.
I resized the QGLWidget using a QSplitter, it acts well.
But after I drag the splitter to the very left to resize the
QGLWidget to zero width, and then I drag it back, the scene
disappears, I
tracked down in debugging mode, the scene is still in the widget,
but why
it
didn't show?
Could anyone please give me some clue, it's driving me crazy.
