Reloading NSTableView on re-focus

In my application, I have a NSWindow that has a NSTableView object and a few buttons. When the user presses the "new" button, an "ItemAdd" NSWindowController is activated where the user types in attributes for the item to be added to the NSTableView.

My question is this: since NSTableView requires reloadDatato update its view, how do I call reloadData after the ItemAdd window closes and focus shifts back to the NSWindow with the NSTableView.

Thanks for the help!

You can subclass the NSWindow and override the following method:
- (void)becomeKeyWindow

You could put reload data in a notification handler:

Put this in an initialization method of an object that you want the notification to get called on:

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didBecomeMainWindow) name:@"NSWindowDidBecomeKeyNotification" object:nil];

Then make a method something like this:

- (void) didBecomeMainWindow
{
    [tableView reloadData];
}
