macOS Current Document Change

[Duke Leto]

I have a tableView in a kind of inspector window, and I want its delegate and dataSource to always be the current document.

I looked at the documentation, and saw no delegate methods for this. I also tried registering for a Key-Value change of current document like this:

[[NSDocumentController sharedDocumentController] addObserver:self  forKeyPath:@"currentDocument"  options:NSKeyValueObservingOptionNew  context:nil];

but it didn't work.

Any suggestions?

Have a look at the windowDidBecomeMain: and windowDidResignMain: delegates from NSWindow. You can use these from within your document to update the inspector.

It is what I use to update my document-inspectors and it works nice and neat. There may be other methods as well though.

Cheers,

Thanks .. I tried it before, but I tried again because of your advice. Turns out I forgot to specify the name when I added the observer.


Works like a charm!
