Re: [PyOpenGL-Users] Beginners question -- How to end OpenGLContext examples

[Mike C. F. <mcf...@ro...>]

Well, clicking in the x in the upper right corner should work fine. 
 With wxPython you can also use the standard (on Windows) Alt+F4 "close 
application" key-combination.  OpenGLContext doesn't do anything special 
with regard to exiting, as when embedded it's hard to come up with a 
"nice" way to kill the application.  Here's a simple example that works 
with the testingcontexts you're likely using:

    def OnQuit( self, event ):
        print 'quitting'
        self.GetParent().Close()

That closes the top-level frame, which is the "preferred" way to exit 
wxPython apps.  Obviously, that wouldn't work with a context that's 
embedded inside a panel or other control.  There are functions in 
wxPython to kill the app regardless, but I'd rather not build those into 
something that's supposed to be flexible in where it's deployed.

Note, however, that the way you were trying _should_ work (and does on 
my machine) i.e. :

    def OnQuit( self, event ):
        print 'quitting'
        import sys
        sys.exit(0)

causes the context to exit on my machine with the wxPython context.  It 
does, however, cause a debug warning from wxPython complaining that it 
couldn't de-register the context's GLCanvas class because there's still 
an open instance of the window.  That's with Python 2.2.2 and wxPython 
2.4.0.2u on Win2k.

HTH,
Mike
