Hi,
I took this code from OSG Active X Example and this problem happens there as
well.
So I'm just trying to find a reason why it's happening.
This is entire code of on CREATE event:
Code:
RECT rect;
GetWindowRect(&rect);
// Set window traits and gc
_traits = new osg::GraphicsContext::Traits;
osg::ref_ptr<osg::Referenced> windata = new
osgViewer::GraphicsWindowWin32::WindowData( GetSafeHwnd() );
_traits->x = 0;
_traits->y = 0;
_traits->width = rect.right - rect.left;
_traits->height = rect.bottom - rect.top;
_traits->windowDecoration = false;
_traits->doubleBuffer = true;
_traits->sharedContext = 0;
_traits->setInheritedWindowPixelFormat = true;
_traits->inheritedWindowData = windata;
try
{
_gc = osg::GraphicsContext::createGraphicsContext(
_traits.get() );
}
catch (...)
{
::MessageBox(0, L"... Exception", L"Hint", MB_OK);
}
_gc->setClearColor( osg::Vec4f(1.0f, 1.0f, 1.0f, 1.0f) );
_gc->setClearMask( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
// Create camera
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(_gc);
camera->setViewport( new osg::Viewport(_traits->x, _traits->y,
_traits->width, _traits->height) );
camera->setProjectionMatrixAsPerspective( 30.0f,
(double)_traits->width/(double)_traits->height, 1.0f, 10000.0f );
camera->setClearMask( GL_DEPTH_BUFFER_BIT );
// Create Screen Capture Handler
osgViewer::ScreenCaptureHandler::CaptureOperation* captureOperation =
new CustomCaptureOperation(_saveScreenshotEvent);
_scnsvr = new osgViewer::ScreenCaptureHandler(captureOperation);
// Create viewer
_viewer = new osgViewer::Viewer;
_viewer->setThreadingModel( osgViewer::Viewer::SingleThreaded );
_viewer->setCamera( camera.get() );
_viewer->setCameraManipulator( new osgGA::TrackballManipulator );
// Switch off the end signal of the viewer main loop
_viewer->setKeyEventSetsDone(0);
// Set root node of the scene
_root = new osg::Group;
_viewer->setSceneData( _root.get() );
_viewer->realize();
// Create a thread for the simulation loop
StartRenderingThread();
MYTRACE_END0;
return 0;
}
So I'm realy running out of ideas what might be the problem.
Thank you!
Cheers,
Danny[/code]
