I'm looking the osgviewerMFC example. It create an MFC window
and use it to create a GraphicContext.
But the GraphicContext create a new OS specific rendering context
(HGLRC on window) and override the event handler(WndProc).
And I don't want that.
I will look to create my own EmbeddedGraphicWindow that implement
makecurrent, swapbuffers, ... functions.

Hi Loinel,
There is a third way, and that is to have one of the native
GraphcisWindow implementations inherit your window data. The
osgviewerMFC takes this approach. Window inheritance is supported
under Win32 and Carbon right now, X11 to come.
Ok for window inheritance. It introduce some OS specific code (we support
both linux and windows, with Qt) but that should be ok.
W.r.t slave camera, you might not need to create one unless you have
something like a HUD or a camera insert. The osgViewer::Viewer is
subclassed from osgViewer::View which in term subclasses from
osg::View, the later of which has a master osg::Camera and a list of
slave osg::Camera. Most apps will just require one Camera and then
master camera will do just fine for this, no need to set a slave
unless you need it.
Slave cameras are not a way to create a new "view" inside another
window ?

Hi,
I'm porting my osg layer to 2.0 and I have some design questions.
I have a view class (for the moment, it contains a sceneview) that
manage
a scene and a camera.
It doesn't handle window creation, gl contexts or window events.
It is used by a higher level application that control all the windowing
stuff. This application can create and destroy windows (one view per
window)
on the fly.
And the 2.0 comes ...
I see 2 ways to achieve this.
- my view class is a osgViewer::Viewer + setUpViewerAsEmbeddedInWindow
to create another window I need to add a slave camera (configured
with the
graphic context returned by setUpViewerAsEmbeddedInWindow)
But the first thing that setUpViewerAsEmbeddedInWindow do is to reset
the threading model to single thread
- implement my own GraphicWindow and use them in the slave cameras
any suggestion ?
