RE: [PyMOL] PyMol with MacOS 10.4

[Warren D. <wa...@de...>]

Konrad,

Heads up:  there are fundamental threading flaws inherent in Aqua/Tcl/Tk
that currently preclude use of PyMOL with them.  Basically, MacOS X
can't feed events to multiple threads -- just a single thread.

So, your either get interaction with the GLUT GUI, or the Tcl/Tk user
interface, but not both : (.

The only solution I can think of is embedding PyMOL into a Tcl/Tk
widget...not something that is possible yet.

By the way, you should be able to build current PyMOL CVS source code
directly agaist MacOS frameworks without MacPython.  But, like I
mentioned above, the end-result isn't optimal -- you get either OpenGL
or Tcl/Tk, but not both. =20

Cheers,
Warren
