Hi Alberto, Strictly speaking I would interpret a resize event as one relating to when a resized. When a window is first created it isn't being resized so a resize event isn't probably appropriate. I could see how it might be convenient a resize event for those using it this way.
For tracking the window size you actually need to use a resize event, you should be able to get the window dimensions to the window, osgGA::GUIEventAdapter attaches the pointer to the window that created it.
