i do that, the following is my resize code: void SS3DCanvas::OnSize(wxSizeEvent& event) { // this is also necessary to update the context on some platforms wxGLCanvas::OnSize(event); // set GL viewport (not called by wxGLCanvas::OnSize on all platforms...) int width = event.GetSize().x, height = event.GetSize().y; //GetClientSize(&width, &height); width = max(5, width); height = max(5, height); // update the window dimensions, in case the window has been resized. getEventQueue()->windowResize(0, 0, width, height); resized(0, 0, width, height); m_HUD->OnSize(width, height); // This is a HACK to un-stick the canvas windows on startup. // For some unknown reason, the canvas windows require a single mouse event before they'll start // responding to user events. By posting a single, mouse up event we un-stick the windows so they'll // respond to the first user event. //wxMouseEvent mouseEvent; //mouseEvent.m_x = 10; //mouseEvent.m_y = 10; //mouseEvent.m_leftDown = true; //mouseEvent.SetEventType(wxEVT_MOTION); //wxPostEvent(this, mouseEvent); } Thibault Genessay wrote: Hi Tamer, Have you tried to pass the new graphics window size to the OSG when it changes ? Your canvas should intercept the resize events and send the updated sizes to all OSG views, e.g. myView->getEventQueue()->windowResize(0, 0, width, height);Thibault On Jan 20, 2008 1:37 AM, Tamer El Nashar <[EMAIL PROTECTED]> wrote:Hi, I am using OSG with wx and I am getting a strange bug on my canvas when dragging and dropping on the canvas, specifically after resizing the canvas. So initially after the canvas is resized and I drag and drop, items show up in the wrong place. Then I click once on the canvas and then when I drag and drop they show up in the write place, as if clicking initializes/fixes something, then everything works. I tried sending my own wxMouseEvent in every size event, and the event does get handled by the osgGA::EventQueue, however that doesnt work. Only actually clicking on the canvas fixes the problem. The code that reports the wrong values is: osgUtil::LineSegmentIntersector::getWorldIntersectPoint(). After clicking once on the canvas, the same code reports correct values! Anyone crossed this before, or any ideas what it could be? I wouldn't even qualify as a OSG novice, so any tips would be much appreciated.
