Thanks so much. >What is happening is that when Boa loads and creates an object (i.e. >wxMenuBar), it loads up RTTI.py and tests the various functions (at >least getters) that can be called on wxMenuBar using the >getMethodType function. In this case, it is calling >wxMenuBar::GetClientRect (really, wxWindow::GetClientRect), but for >whatever reason the wxMenuBar C++ object is not prepared for a >GetClientRect() call and thus crashes. > >I say 'for whatever reason' because I didn't go through the Boa code >well enough to know exactly what state the wxMenuBar is when this >function is being called, but my guess is just that regardless, >GetClientRect() on Mac doesn't expect to be called from wxMenuBar. >On Mac, wxMenuBar really isn't a wxWindow at all but it derives from >it for compatibility with other platforms. > >I can fix things at the wxMac/C++ level for GetClientRect (actually, >GetClientSize and GetClientAreaOrigin), but that won't make it into >wxPython until the next release. > However, I do have to wonder why the getters are actually being >called and tested.

Ok, now I want to say a few things. 1) If you will fix the c++ side of this matter I'd be really grateful ! 2) I understand that the fix will be available in the next release of wxPython but don't worry. I have no commitment to this project I was just trying to help. I think I'll try to use Boa on any Linux distro I could install on my machine. I hope wx stuff is more stable, there. As far as I could see, Boa is really nice and it is able to support the creation of a GUI app well enough, for me. 3) Thanks for your higly informative words about what's going on inside Boa that leads to this crash. 4) If I jump the menubar phase and step in the following phase I could go on with the tutorial. I'm sure I'll find some other crashes like this. Could it help if I report about them too ? 5) I found at least a crash occurring always in the same step also in wxGlade. Could it help if I report about that too? Thanks so much for your help, anyhow :-) Bye Adriano _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
