Hello!
If the constructor of the wx.ClientDC class is called with None (instead
of a canvas) as the only argument, it will cause a segmentation fault.
Is that the expected behavior?
I stumbled across this while playing with OGL and a meaningful Exception
would have saved me quite some time.
Regards,
Daniel Hepper
Hi Daniel,
If the constructor of the wx.ClientDC class is called with None (instead
of a canvas) as the only argument, it will cause a segmentation fault.
Is that the expected behavior?I stumbled across this while playing with OGL and a meaningful Exception
would have saved me quite some time.
From the docs:
"""
wxClientDC::wxClientDC
wxClientDC(wxWindow* window)
Constructor. Pass a pointer to the window on which you wish to paint.
"""
I believe it's normal that it crashes, isn't it?
Andrea.

You could argue raising an assertion is more well behaved than a segmentation fault.

It is, but we don't live in a perfect world, so this might be a
possible enhancement in error-handling for future versions of
wxPython.
I have no idea if this should be fixed at the C++ level or directly in
wxPython, but I am sure Robin will accept a patch 
Andrea.

the platform you are using?
No, I'm using version 2.8.3, the prebuilt binary for Ubuntu 7.04 from
the wxPython repositories.
