I'm facing a problem with a view-based NSTableView running on 10.8 (target is 10.7, but I think this is not relevant). I'm using an NSTableView, and I get content values for my custom NSTableCellView through bindings. I use the obejctValue of the NSTableCellView to get my data. I added a button to my cell, and I'd like it to trigger some action when clicked. So far I have only been able to trigger an action within the custom NSTableCellView's subclass. I can get the row that was clicked like this, using the chain: NSButton *myButton = (NSButton*)sender; NSTableView *myView = (NSTableView*)myButton.superview.superview.superview; NSInteger rowClicked = [myView rowForView:myButton.superview]; From there I don't know how to reach my App Delegate or controller where the action is defined. As I am using cocoa bindings, I do not have a delegate on the NSTableView that I could use to trigger my action. Do you have any idea how I could talked back to controller ? Many thanks in advance!
