Question

Is it possible to make my NSTableView accept a deleteevnt (backspace og even cmd+backspace) ? I have an NSMenu where i have my delete-menu-item connected to my first responder object in the nib.

Any pointers?

You could create a subclass of NSTableView, overriding keyDown like so:

- (void)keyDown:(NSEvent *)theEvent
{

    unichar key = [[theEvent charactersIgnoringModifiers] characterAtIndex:0];
    if(key == NSDeleteCharacter) 
    {

        [self deleteItem];
        return;
    }

    [super keyDown:theEvent];

}

Then make sure that any NSTableView that you want to have the delete functionality uses your subclass in Interface Builder instead of the regular NSTableView.

You can implement the - (void)deleteItem method for example like this:

- (void)deleteItem
{
    if ([self numberOfSelectedRows] == 0) return;

    NSUInteger index = [self selectedRow];

    [documentController deleteItemWithIndex:index];

}
