NSTableView event and backspace (delete row) - fieldeditor / firstresponder?

Question

Is it possible for my NSTableView to accept deleteevnt (backspace og even cmd + backspace)? I have an NSMenu where I have a delete-menu-item element associated with my first responder in nib.

Any pointers?

Answer 1

You can subclass NSTableView by overriding keyDownas follows:

- (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 you want to use for deletion uses your subclass in Interface Builder instead of the usual NSTableView.

You can implement the method - (void)deleteItem, for example, as follows:

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

    NSUInteger index = [self selectedRow];

    [documentController deleteItemWithIndex:index];

}
