Hi all.
I have a small problem where I
use osg::GraphicsContext::createGraphicsContext to create a context for a
window-widget (in .NET), but I also use another piece of software that
use wglGetCurrentContext to check for context.
But wglGetCurrentContext() returns null for the context that OSG creates.
My init method:
bool GraphicsWindow::initOSG( HWND hwnd)
{
if (m_viewer.valid())
return true;
m_viewer = new osgViewer::Viewer();
m_viewer->setThreadingModel( osgViewer::ViewerBase::SingleThreaded );
m_root = new osg::Group;
m_viewer->setSceneData( m_root.get() );
m_traits = new osg::GraphicsContext::Traits();
m_traits->inheritedWindowData = new
osgViewer::GraphicsWindowWin32::WindowData( hwnd );
m_traits->setInheritedWindowPixelFormat = true;
m_traits->doubleBuffer = true;
m_traits->windowDecoration = true;
m_traits->sharedContext = NULL;
m_traits->supportsResize = true;
RECT rect;
::GetWindowRect( hwnd, &rect );
m_traits->x = 0;
m_traits->y = 0;
m_traits->width = rect.right - rect.left;
m_traits->height = rect.bottom - rect.top;
m_graphicsContext = osg::GraphicsContext::createGraphicsContext(
m_traits.get() );
m_viewer->getCamera()->setGraphicsContext( m_graphicsContext.get() );
m_viewer->getCamera()->setViewport( new osg::Viewport( 0, 0,
m_traits->width, m_traits->height ) );
m_viewer->getCamera()->setProjectionMatrixAsPerspective(30.0f,
static_cast<double>(m_traits->width)/static_cast<double>(m_traits->height),
1.0f, 10000.0f);
m_viewer->realize();
m_viewer->frame();
assert(wglGetCurrentContext()); // Fails
I have tried m_graphicsContext->makeCurrent();
wglGetCurrentContext STILL returns null...
I know that I'm missing something, question is what?
/Anders
