Robert, Thanks for the info. Looking at the code I don't understand how to set the handle for which window to have osg render to. I have an application that has an existing control that I want OSG to render into. I get the handle of that control and then how can I use that to tell OSG where to render. With GraphicsWindowWin32 I can use the following code to do what I need but I don't see how to do it with GraphicsWindow only. osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits;
osg::ref_ptr<osg::Referenced> windata = new
osgViewer::GraphicsWindowWin32::WindowData(m_hWnd); //m_hWnd Handle to windows
control for OSG to render to.
traits->x = 0;
traits->y = 0;
traits->width = rect.right - rect.left;
traits->height = rect.bottom - rect.top;
traits->windowDecoration = false;
traits->doubleBuffer = true;
traits->sharedContext = 0;
traits->inheritedWindowData = windata;
osg::ref_ptr<osgViewer::GraphicsWindowWin32> gw = new
osgViewer::GraphicsWindowWin32(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(dynamic_cast<osg::GraphicsContext*>(gw.get()));
At this point, would you see any harm in specifically including
GraphicsWindowWin32 (header and cpp) in my project so that I have access to
them?
Thanks,
Mike

Hi Mike,
Current the subclasses from GraphicsWindow found in include/osgViewer/api/*
like GraphicsWindowWin32 aren't yet included publically listed headers. This
does need to change, so we'll need to evolve the src/osgViewer/CMakeLists.txt
to support the include/osgVIewer/api/* directories/files that are approrpriate
for that platform.
However, even with out this GraphicsWindowWin32 being included things should
still compile and run, as GraphicsWindowWin32 will work behinds the scenes as a
default implementation of GraphicsWindow for Windows.
Robert.

All,
Not sure if this is intentional, oversight, or my misunderstanding.
I do a full build with CMake (Visual Studio 8) and everything builds fine but
when I go to use osgViewer in my existing MSFC application I don't have
GraphicsWindowWin32 in the CMake output directory for
"openscenegraph/include/osgViewer" and when I check out the lib that is
produced there is no GraphicsWindowWin32 functions in the lib. When I look
over the files that are compiled I do see that GraphicsWindowWin32 is compiled
but it does not seem to make it into the library.
Am I missing a define so that GraphicsWindowWin32 is included in the
distribution or is there something else?
Thanks for any help.
Platform: Windows XP
Compiler: Visual Studio 8
Thanks
Mike Hartman
