Hi Robert & Mike
I tested the osgViewerMFC of the 1.9.6 version, with the
PFB_DOUBLEBUFFER defined,
and I get exactly the same results.
I have no idea of what can be wrong.

Hi Mike & Miguel,
First up the PFB_DOUBLEBUFFER was fixed by Mike last week, so is part
of the 1.9.6 release.
Second up, not sure why the optimizer might fail. I haven't used this
example at all (I work under Linux), in general the optimizer does
crash.
Thirdly, this is a note for Mike, the threads on exit should clean
themselves up automatically, but... if the graphics context is deleted
before viewer threads are stopped then it could cause problems that
the viewer can't do anything about. On close windows you should see
if you can defer the window close to the viewer to handle.
Alternatively call stopThreading on the viewer on the windows.
Finally I have to add this example is really an example that would
probably be best done using CompositeViewer with each new window a
separate View rather than a separate Viewer.
Robert.

Not sure why the optimizer crashed but with the second issue I had
the same problem on my home computer and found that the pixel
description needed to have PFD_DOUBLEBUFFER defined. Once I added
this I was able to see the object but without it all I had was a blue
background for the window. Please check to make sure that your pixel
description has this defined (located in the MFC_OSG.cpp file). I
know that the latest subversion contains this change.
As for the last issue; I have also seen this (on my home pc, it is
intermittent) and believe it is a threading issue (trying to close
the window before all threads have exited) and I don't have much
experience with threading so I would have to rely on the community to
get into the code and figure out how to fix the issue.
Thanks,
Mike

Subject: [osg-users] about the osgViewerMFC example
Hi all,
I have the 1.9.5 OSG release, and testing the osgViewerMFC example I
have found several problems:
- When loading a model, optimizer.optimize crashes
- When I comment this line, the program runs correctly but when I load a
file, I dont see the model, just an empty scene.
- When I close the app, the program crashes in
CMDIChildwindow::MDIDestroy()
I'm using VC.NET 2003.
Am I the only one with this problem ? Am I doing something wrong ?
Can someone post another more stable example using MFC's ?
thanks !
