RE: [Plib-users] wxWindows and SSG together?

  Has anyone on this list tried using wxWindows and PLIB/SSG together?  It
seems like a good combination (open source GUI, open source 3D).

  It should work well since wxWindows can set up an OpenGL context, and SSG
just draws into the current context.  However, my attempts so far to combine
the small wxWindows OpenGL sample program with some SSG functions has not
been successful - the SSG objects aren't appearing.

  Has someone used them successfully, and if so perhaps someone has a small
sample program with them working together?

  Hi Ben,

  Welcome aboard. :-)

  Using the FLTK windowing kit was fairly easy to do
  There are some minor yet show stopping gottchas however.
  i.e you have to make sure that you have a valid GLContext
  prior to any SSG calls.

  basically all you should need to do is derive a new class
  from wxGLCanvas and attach a ssgContext

  You can look at the PPE source
  http://sourceforge.net/projects/prettypoly
  To see a way to do this
  The pertinent code is in src/viewer/ppeViewer.cxx
  esp. ppeViewer::init()

  Watch out for possible confusion of
  wxGLCanvas::SetCurrent()  and
  ssgContext::makeCurrent()

  MakeCurrent() !!! MUST !!! come after SetCurrent()

  Cheers
