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

[Ben D. <be...@wa...>]

Hi Norman, it feels good to be here, i hope i can find a way to stay =
with PLIB.

I checked my test program to confirm that the contexts are being treated =
properly, yet the SSG graphics will not appear, and in fact seem to mess =
up the display of OpenGL calls even when the ssgCullAndDraw is called =
second.

Does PPE use wxWindows, FLTK, or something else?  I tried to acquire the =
PPE source to look at the module you indicated, but when i downloaded =
and opened the file "prettypoly-cvsroot.tar.gz", all the files had ",v" =
in their names and had jumbled contents, as if the were were some kind =
of CVS-internal format.

    Has anyone on this list tried using wxWindows and PLIB/SSG together? =
 It seems like a good combination (open source GUI, open source 3D).=20
    =20
    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.
    =20
    Has someone used them successfully, and if so perhaps someone has a =
small sample program with them working together?=20

    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.
    =20
    basically all you should need to do is derive a new class
    from wxGLCanvas and attach a ssgContext
    =20
    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()
    =20
    Watch out for possible confusion of=20
    wxGLCanvas::SetCurrent()  and
    ssgContext::makeCurrent()
    =20
    MakeCurrent() !!! MUST !!! come after SetCurrent()
