Re: [Pyobjc-dev] sigbus with TableView delegates

[<bb...@ma...>]

Did you declare your table data source or table delegate as a class 
that implements NSTableDataSource or NSTableViewDelegate?

If not, the problem is that PyObjC has no way of knowing that your 
implementation of said method should take, say, an integer for the 
rowIndex argument vs. an object.  It assumes object and interprets the, 
say, row 1 index as an object pointer -- *boom*.

I.e.:

class TableFoo(SuperFoo, NSTableDataSource):
     .... implement methods ...

Ahhh... there is no NSTableViewDelegate.   Now there is.  Update from 
cvs and rebuild... then declare your class as:


class TableFoo(SuperFoo, NSTableDataSource, NSTableViewDelegate):
     .... implement methods ...

I updated the TableModel2 example to demonstrate the use of 
tableView_shouldSelectRow_().
