Hi Nick, >this belongs in a loop.

I tried to simplfy the code as below but it raises segmentation fault at the last line fWndProc.Am I really messing something with pointers there ? osgViewer::CompositeViewer::Windows wins;g_viewer->getWindows(wins); MSG msg; if (::PeekMessage(&msg,NULL,0,0,PM_NOREMOVE)) { ::GetMessage(&msg, NULL, 0, 0); if (wins.size()) { osgViewer::GraphicsHandleWin32 *hdl = dynamic_cast<osgViewer::GraphicsHandleWin32*>(wins.at(0)); if(hdl) { MSG message =msg; WNDPROC fWndProc = (WNDPROC)::GetWindowLongPtr(hdl->getHWND(), GWLP_WNDPROC); fWndProc(hdl->getHWND(), message.message, message.wParam, message.lParam); } } } Regards,

Here is a snippet of an example: MSG msg; if (::PeekMessage(&msg,NULL,0,0,PM_NOREMOVE)) { ::GetMessage(&msg, NULL, 0, 0); lib->postMessage((void*)&msg); } this belongs in a loop. Here is the lib::postMessage osgViewer::CompositeViewer::Windows wins; _viewer->getWindows(wins); #ifdef WIN32 if (wins.size()) { osgViewer::GraphicsHandleWin32 *hdl = dynamic_cast<osgViewer::GraphicsHandleWin32*>(wins.at(0)); if(hdl) { MSG* message = (MSG*)msg; WNDPROC fWndProc = (WNDPROC)::GetWindowLongPtr(hdl->getHWND(), GWLP_WNDPROC); fWndProc(hdl->getHWND(), message->message, message->wParam, message->lParam); } } #endif Cheers,Nick On Mon, Aug 11, 2014 at 10:45 AM, Sonya Blade <sonyablade2...@hotmail.com> wrote: Dear All, When we try to integrate the OSG rendering context into another Win32/64 window via window handle do we need to hook also the message handling mechanism ?

I place the code which deals with window handle equalization in a kinda unusual way, under the button click, after clicking the button blue screen shows up but cessna is not loading, I mean physically the cessna is not loaded, I can not spot/testify exactly whether the malfuncitoning is due to the unusual way of placing the window handle dealing code under the button click or something else ? So basically is there any workaround to load the object ? void wid_testFrame::OnButton1Click(wxCommandEvent& event) osg::ref_ptr<osg::Referenced> windata = new osgViewer::GraphicsWindowWin32::WindowData( HWND( wxFrame::GetHandle() ) ); osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits; traits->x = 0; traits->y = 0; traits->width = 800; traits->height = 600; traits->windowDecoration = false; traits->doubleBuffer = true; traits->inheritedWindowData = windata; osg::ref_ptr<osg::GraphicsContext> gc = osg::GraphicsContext::createGraphicsContext( traits.get() ); ........... osg::ref_ptr<osg::Node> load_model = osgDB::readNodeFile("cessna.osg"); if (!load_model ) { ............ /////////////////ALWAYS FALSE } ............ viewer.run(); _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- trajce nikolov nick _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
