I have been busy playing with this. You can have an osgViewer embedded in a FLTK window. I haven't tried to render with multiple threads yet, but it works for a single thread. You can draw FLTK windows in multiple threads but you have to use a mutex (part of the FLTK system) so you can only draw in one window at a time. I am not sure if this also applies to OpenGL (and thus OSG) drawing in FLTK windows.
Under Linux (and Windows I think) you can have an OSG window that processes OSG events in a separate thread from your FLTK window in the FLTK thread processing FLTK events. This approach does not work on the Mac, and I'm not entirely sure why. I had to combine my two event processing threads into one to get it to work on the Mac. One annoying limitation in this approach is that if you are selecting an FLTK menu, OSG rendering stops in your other window. There seems to be no way around this. I am playing with an improved FLTK viewer which expands upon the osgviewerFLTK example, but it is still in progress. -Eric On Tue, Apr 14, 2009 at 12:03 PM, Tueller, Shayne R Civ USAF AFMC 519 SMXS/MXDEC <shayne.tuel...@hill.af.mil> wrote: > Another question… > > > > Can you have an osgViewer embedded in a FLTK windowing framework?
