Hi Peter,
hmm not sure whats wrong can you try to check via the "depends.exe" tool
that the right qt library is loaded.
Andreas
Ah oops, totally forgot that.
I managed to compile and link with QT now, but when I run my app, I get the
following error:
"QPaintDevice: Must construct a QApplication before a QPaintDevice".
Do you have an idea what might be wrong? I understand the error, but I am
creating my QApplication-object before anything else!
My main looks like this:
// initialize OSG
OSG::osgInit(argc, argv);
// initialize QT
QApplication::setColorSpec(QApplication::CustomColor);
QApplication a(argc, argv);
// create windows
QGLFormat::setDefaultFormat(QGLFormat(QGL::DirectRendering |
QGL::DoubleBuffer | QGL::DepthBuffer | QGL::Rgba));
// initialize scene
Scene* scene = new Scene("data/world.xml");
// initialize window
SceneWindow* sceneWindow = new SceneWindow();
OSG::QTWindowPtr win = OSG::QTWindow::create();
win->setGlWidget(sceneWindow);
sceneWindow->m_simpleSceneManager.setWindow(win);
sceneWindow->m_simpleSceneManager.setRoot(scene->getRoot());
sceneWindow->m_simpleSceneManager.showAll();
// process events
a.processEvents();
// show scene
sceneWindow->show();
a.setMainWidget(sceneWindow);
return (a.exec());
Thanks a lot Andreas,
Peter

Hi Peter,
QTimer needs a running qt event loop, something like this ...
QApplication a( argc, argv );
a.exec();
this conflicts with the glut event loop.
Andreas
I'm only using QTimer.h, so it's not possible to combine that with
GLUT-functions?
I'll check that example out, thanks
Peter

Hi Peter,
what do you mean with "glutIdleFunc(glutIdleCallback)" are you using
glut in a qt application? That's not a good idea you can use a qt widget
for rendering just look into
OpenSG/Source/WindowSystem/QT/testPassiveQT.cpp
Andreas
Hi all,
Any idea why QTimer and QThread of QT (www.trolltech.com) aren't
working
anymore when using OpenSG?
I think it has somethinig to do with "glutIdleFunc(glutIdleCallback)",
so
the QThread/QTimer-object isn't given time to do their jobs.
On request I can provide my framework, maybe it has something to do
with
a
project setting. (MSVC6)
Thanks a lot,

Peter
