Hi J-S,
I found some rough edges in the osgQtBrowser example. Testing was on an
AMD-64 system running SusE 10.1.
-Don
1) osgQtBrowserd --useWidgetImage
runs OK; resize & event handling good; Memory fault on exit.
gdb had this diagnostic:
Program received signal SIGSEGV, Segmentation fault.

Mutex may be an inlined function, or may be a template function

2) osgQtBrowserd --useWidgetImage --fullscreen
dies on start-up:

3) osgQtBrowserd --useWidgetImage --useBrowser
like #1 except all white quad instead of text;
disabled code to by-pass WebKit likely to blame:
QPainter::begin: Paint device returned engine == 0, type: 3
QPainter::setCompositionMode: Painter not active
QPainter::setCompositionMode: Painter not active
QPainter::end: Painter not active, aborted
Memory fault
4) osgQtBrowserd --useWidgetImage --useBrowser --fullscreen
disabled code

5) osgQtBrowserd --useWidgetImage --sanityCheck
OK with your sanity clause. QT & OGS in seperate windows.
6) osgQtBrowserd --useWidgetImage --fullscreen --sanityCheck
Same as #5; not full sceen even after unsetting "OSG_WINDOW=0 0 800 600".
7) osgQtBrowserd --useWidgetImage --useBrowser --sanityCheck
Like #5 except Qt Window all white; hits "disabled code".
8) osgQtBrowserd --useWidgetImage --useBrowser --fullscreen --sanityCheck
Like #7; not full screen.
