osx - NSTableView single click action -

-

how capture event of single-clicking on row of nstableview , trigger action? (idealy, should trigger action left clicks only, not right clicks, not required.)

implementing -tableviewselectiondidchange of table view's delegate close want. however, if row selected, clicking on row again doesn't call -tableviewselectiondidchange since selection didn't change.

connect selector action event on table view (better interface designed), 

- (ibaction)onaction:(id)sender {     nstableview* tableview = (nstableview*)sender;     // use tableview.selectedcolumn/tableview.selectedrow selection }

you can connect code if want fro viewdidload:

[self.tableview setaction:@selector(onaction:)];
