[osg-users] set proper size to window manager at startup

[Gianni Ambrosio]

Hi All,
I have a Qt application ad I have to initialize a WindowManager with some default width and height like follows:

osg::ref_ptr<osgWidget::WindowManager> wm = new osgWidget::WindowManager(view, 1280.0f, 1024.0f, MASK_2D, osgWidget::WindowManager::WM_USE_RENDERBINS);

When the Qt application starts up then the QWidget containing the OSG view is resized properly by the Qt framework but even if I use:

view->addEventHandler(new osgWidget::ResizeHandler(wm, camera));

an osgGA::GUIEventAdapter::RESIZE event is not raised at that point. That means, every OSG windows added to the WindowManager are not resized correctly. Only when the user interactiverly resizes the window of Qt application, then a osgGA::GUIEventAdapter::RESIZE is rised and, falling into ResizeHandler::handle() methodm the Window Manager is updated with proper width and height.

Now, which is the correct way you see to solve this issue?

Regards,
Gianni
