Briefly, you can configure the checkbox cell (either in IB or programmatically) to have an action, and possibly an explicit target. In the action method, you can use NSTableView's 'clickedRow' method to find the row and hence the object whose "marked" property changed, and send a message representing to the change directly to whatever object has to be notified. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
