How to bring NSWindow to front and to the current Space ?

Question

I'm using this code to bring up my window:

[self.window makeKeyAndOrderFront:self];
[self.window setOrderedIndex:0];

But often it will be beneath other windows or displayed in other Space desktop that I last open it in. How do I make it always appear "in front" to the user?

Update I found the answer from previously asked question; make the window show up to the top of other windows: [NSApp activateIgnoringOtherApps:YES];

But how to move the app to the user's current Space?

Answer 1

To bring your app to the front:

[NSApp activateIgnoringOtherApps:YES];

Answer 2

Perhaps you want:

  [self.window setCollectionBehavior: NSWindowCollectionBehaviorCanJoinAllSpaces];

Experiment with the other collection behaviors... I found NSWindowCollectionBehaviorMoveToActiveSpace was a bit buggy in 10.5 but it might be better now.

Answer 3

But how to move the app to the user's current Space?

You don't. Spaces hold windows, not applications. (That's why the collectionBehavior property is on NSWindow, not NSApplication.)
