Hi Don,
I got my windows working, but now I have two more problems which I
cannot solve.
The first thing is that, when I close one window (which is not the main
window, I call it "sub-window") the content of the sub-window will be
drawn into the main window instead of the main window's content (or the
content will be overwritten, I don't know). The funny thing is that this
is only happening on Windows, when the sub-window will be closed on
Linux, the whole application exits. Here are two screenshots which show
the problem (on Windows):

The second problem: How I can prevent that the window size can be
changed by the mouse? Is this possible at all? And can I set a parent
window to which the sub-window always lies in front of, even when the
parent window has the focus?
regards,
Oliver

Hi Oliver,
Robert once said that less lines of code constitutes cleaner code.
Here is an example that is three times cleaner than osgprerender:
http://www.andesengineering.com/misc/pbufex.zip
In a nutshell, the program does just what you are asking for:
1. Camera one is set up to render to a PBuffer
2. A post draw callback copies the contents of the pbuffer to an
osg::Image
3. Camera 2 is set up to render to a Window.
4. At frame time, it does a BLT (with a single glDrawPixels()) to the
window.
You may do image processing on the image between camera 1's frame and
camera 2's frame.
Cheers,
-don

Oliver,
You can set up your camera to render to an image. Look at the
osgprerender example. It should explain much.
Cheers,
