Creating a resizable window

[tsadok]

I'd like the main frame of my new addon to be resizable. At the moment clicking and dragging just moves the frame around. What other components does it need? Something like the resize corner in the picture?

Thanks!

Edit: Of course I only needed to post this to think about it a little more. Does anyone have experience with Frame:StartSizing("point") ?

Yes, you can download and see WowLua for an example of a resizeable frame.

self:GetParent():StartSizing()

That's just what I wanted. Thank you!
