Custom NSWindow drawing

Question

I want to draw an NSWindow that looks similar to this:

In that it has a typical NSWindow appearance with the bottom bar and such, but instead of a title bar at the top, I want to draw a little arrow.

Is there a simple way to do this? Do I have to draw the entire window by hand (bottom bar and all) ? Or can I slightly modify the existing NSWindow layout to just draw that arrow at the top? Thanks

Answer 1

You could possibly fake the title bar by using a second child window that overlays the top section of the window and draws just the arrow. Otherwise, you'd need to draw the whole thing yourself.

Answer 2

Not sure what you mean by a simple way to do it, but it's not very hard to make your own window subclass and draw the window controls yourself. A child window would be a bit of overkill for this situation.

Have a look at the Round Transparent Window sample project.
