Hi Marco,
> But how do I get a HWND of the viewer?
if (_viewer.valid())
{
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
}
you have to construct your MSG message .. this is a snippet from my app
Hope it helps
Nick
