NSWindow - show new window that will always stay on top of current window

Question

I want my NSWindow to show new window(s) that will always be on top of current window. they should NOT be on top of other windows.

In addition, they should not move when the original window moves.

How can i do that?

Answer 1

Use NSWindow's addChildWindow:ordered: or setParentWindow: method to add the other window as a child of the first window. That window will follow the first window around. See the NSWindow Class Reference.
