[Fxruby-users] FXGLLine in glviewer

[Peter J. P. <PJP...@UC...>]

Hi,

I'm just trying to learn how to use OpenGL in FXRuby.  I tried
to add the drawing of a line to the glviewer example, using a
statement completely analogous to the other objects in the scene,
namely,

  gp2.append(FXGLLine.new(-1.0,-1.0,-1.0, 1.0,1.0,1.0))

placed after the FXGLCylinder statement, and this produces the
error message:

  in `append': This FXGLObject * already released (RuntimeError).

It makes no difference if I create and name the object in a separate
statement, and then append it to the group of FXGLObjects; the error 
still occurs with exactly the same message.

Have I done something completely stupid, or is this a bug?

Peter
