Just got this limping around.

wx._core.PyAssertionError: C++ assertion "m_window" failed at

Yes, we've known about this but not one has submitted a patch to us to fix it.

 

There is a workaround for any given application here: http://imyy.in/blog/?p=26  

It seems that this can be made more general by putting it the wxgui top_block::__init__ itself:

$ diff -btwc  ../gr-wxgui/grc/top_block_gui.py.orig ../gr-wxgui/grc/top_block_gui.py

                  self.GetWin = self._panel.GetWin

+                 self.Start(False)

 

          def SetIcon(self, *args, **kwargs): self._frame.SetIcon(*args, **kwargs)

 

Ok, that's great that there seems to be a fix out there for the WX 3.0 problem. Will this cause any other side effects in the applications? Will it work for WX < 3.0?
