I subclassed NSTableView but (BOOL)textShouldEndEditing:(NSText *)textObject
Is never called.
In my table delegate I implement:
- (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText
*)fieldEditor
{
if ([[fieldEditor string] length] == 0)
return NO; // don't allow empty names
else
return YES;
}
This works when editing a cell in a table row when I press return
If I change this to:
- (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText
*)fieldEditor
{
return NO;
}
And start an edit session, if addObject is called on the ArrayCOntroller
feeding the tableView, the cell edit session ends without this method ever
being called.
However: - (void)controlTextDidEndEditing:(NSNotification *)obj
IS called.
How can I prevent the edit session from ending when adding items to the
array controller feeding the table view?
Note that if I
