Re: NSTable: Notification on selection of already selected row.

Hi Danny,

There is a few possibilities. It depends on what you are trying to do.

1) From your delegate implement either:

- (BOOL)tableView:(NSTableView *)aTableView shouldSelectRow:(int)rowIndex

- (void)tableViewSelectionIsChanging:(NSNotification *)aNotification


2) In a NSTableView subclass, override:

- (void)mouseDown:(NSEvent *)theEvent

And call [self rowAtPoint:aPoint] to obtain the clicked row. Do not forget
to call [super mouseDown: theEvent].


3) Maybe another solution, which is best suited for your need, if we just
know what you are trying to do.
