[Pyobjc-dev] Example of how to use NSOutlineView?

[Ben G. <bg...@ob...>]

I'm trying to use an NSOutlineView yet the application just crashes 
with a signal 10 bus error or signal 11 segmentation violation when it 
tries to update it.  I've read about how the NSOutlineView only holds 
onto references to objects without bumping their reference counts and 
I've tried to take that into account but I'm still struggling.  I was 
wondering whether anyone had an example of an app that used an 
NSOutlineView that I could swipe, er, I mean, examine?

Also, is there a better way to debug problems causing sig 10 or 11 than 
attaching via to the process with gdb and checking the stack trace?  
It'd even be nice if you could launch a pyobjc app from ProjectBuilder 
under the debugger and look at the stack trace there.  At present when 
you do that, it complains about missing stack frames.

Thanks, we're loving pyobjc,

	Ben.
