How to write an own resize corner/handle for an NSWindow?
How can I write an own resize corner/handle for an NSWindow? I'm using a subclass of an NSWindow without the default resize corner, but I need it for my window.
Solution
The basic outline:
Create a view.
Put some "drag me" indicator appropriate to your window in the view.
Have the view's drag action method respond by resizing the window so that the corner in question is now located at the current mouse position.
