[PyOpenGL-Users] How to select an object

[duncan d. <dun...@gm...>]

Hello

I am playing with python and pyopengl.
I have not any problem to draw the object and so on, but then I'd like
to select an already drawn object.

The code is attached

Running it I get this error:

--------- pick3d ----------
 - nhits = 0
hit nothing
 - selectedObjects:
Traceback (most recent call last):
  File "C:\software_personale\openboat\code_snippets\hellogl.py", line
143, in mouseReleaseEvent
    self.pick3d(event)
  File "C:\software_personale\openboat\code_snippets\hellogl.py", line
257, in pick3d
    return self.processBuffer()
  File "C:\software_personale\openboat\code_snippets\hellogl.py", line
274, in processBuffer
    print " - selectedObjects: ", self.selected
AttributeError: selected


As you can see, the function is called in the mouseReleaseEvent (O
also tried the mousePressEvent)
Any idea (or link) on how I can select an object ? My goal is to be
able to select a point and drag it around the viewport,
beeing able to get the new position

Any hints ?

thanks in advance
bye
