I already checked the fWndProc, it is not NULL but still raises the exception,
very weird.

No, you are calling the WndProc in the last line explicitly. It has to be in a
loop for example where you are calling viewer->frame(); Also check if fWndProc
is NULL

With this I assume you mean that we have to embed/hook the first code poriton
into WndProc loop, right ??Because all this are runing under the OnButtonClick
for me, I'll chage it hooked into main window WndProc
but for time being I use it for testing purposes.
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); } }
}

Hi Sonya,
although on Windows is sufficient to set the window handle in the traits, based
on your app you might really want to pass the messages explicitly. 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

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 ? If so can you give me
an example for that ?

Subject: [osg-users] Integrating OSG in C::B wxWidgets
Dear All,
I'm trying to integrate the OSG view into wxWidgets actually wxFrame object in
C::B IDE, I configure
the Window handles to match with wxFrame and OSG graphic context but I get only
a blue screen without cessna loaded.
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();
