Hi all,
I have a problem with an ActiveX control using osg. I have it working well
in osg 1.x but when I have migrated it to osg 2.x (changing the producer viewer
to osgviewer), the OnPaint function of the control is never called and I can
not update the osg graph. I think it is a problem with my configuration of the
viewer. I have this in the main class of the control:
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;
osg::GraphicsContext* gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc);
camera->setViewport(new osg::Viewport(0,0, traits->width, traits->height));
GLenum buffer = traits->doubleBuffer ? GL_BACK : GL_FRONT;
camera->setDrawBuffer(buffer);
camera->setReadBuffer(buffer);
m_SceneView->addSlave(camera.get());
if I comment the "traits->inheritedWindowData = windata;" line, all works ok,
it is updated an all the events occurs, but the osg frame appears as a separate
window, however, if I use this line it appears integrated in the browser but
onPaint function is never called. I would thank you if somebody can help me.
Best regards,
David._______________________________________________
