I have error a bus error on MacOSX when doing a
GetBestVirtualSize() on a wx.MenuBar generated by
xrced. See attached error dump. GetBestVirtualSize() on
other objects seem fine. Other platforms are ok.

This is with Python 2.4.1 and wxPython

I can't say I'm all that suprised, because a MenuBar on OS X
has a fixed size. Does it do this when the wxMenuBar is not
generated by xrced?

Does this report make any sense?

There is a standard menu bar on OSX and it does not make much sense to change the size on it do something with the size/position with the menu on Mac OSX.

The sizing functions for Mac OSX should give an assert.

This probably should be changed accordingly.

Should we just generate an assert when the menu bar changes size on OSX? With the text like: "changing size of the menu bar is not supported on Mac".

The point of this bug is that calling wxMenuBar::GetSize() on OS X used to crash. If this is still the case, we must fix it. It doesn't matter that much what does the method -- if it could return the actual menu bar height, it would be better, of course, but if it returned wxDefaultSize it would still be better than crashing.
