Hi all,
I'm developing an ActiveX for a web browser using osgViewer. This is the
configuration that I have used in order to attach the viewer to the window. It
is included in my main activex control class:
RECT RectDLG;
GetWindowRect(&RectDLG);
// Init the GraphicsContext Traits
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new
osg::GraphicsContext::Traits;
// Init the Windata Variable that holds the handle for the Window to
display OSG in.
osg::ref_ptr<osg::Referenced> windata = new
osgViewer::GraphicsWindowWin32::WindowData(GetSafeHwnd());
// Setup the traits parameters
traits->x = RectDLG.left;
traits->y = RectDLG.top;
traits->width = RectDLG.right - RectDLG.left;
traits->height = RectDLG.bottom - RectDLG.top;
traits->windowDecoration = false;
traits->doubleBuffer = true;
traits->sharedContext = 0;
traits->setInheritedWindowPixelFormat = true;
traits->inheritedWindowData = windata;
// Create the Graphics Context
osg::GraphicsContext* gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
m_SceneView->getCamera()->setViewport(new
osg::Viewport(0,0,traits->width,traits->height));
m_SceneView->getCamera()->setProjectionMatrixAsPerspective(30.0f,
static_cast<double>(traits->width)/static_cast<double>(traits->height), 1.0f,
10000.0f);
m_SceneView->getCamera()->setGraphicsContext(gc);
m_SceneView->setThreadingModel(osgViewer::Viewer::SingleThreaded);
The update of the scene is done in the OnPaint function (with
m_SceneView->frame()). My problem is that the OnPaint function is called but my
scene is not visually updated.
I think my problem is due to osg doesn't know that the scene is active and i
need a function as makeCurrent in Producer::RenderSurface. I have seen this
function in osgViewer it is protected, is there another similar function or
something that tells osg that the scene is active?
Thank you in advance,
David._______________________________________________
