TextView, TextBuffer and copy-paste, undo/redo?

["Gabor Szabo" <szabgab gmail com>]

I am trying to add windows with editing capabilities to my app.
I started with a TextView and a TextBuffer in it but as I can see out of the box
it only supports simple editing. Do I have to implement copy-paste, undo/redo
myself or is there a widget that I can use and will already provide all this?
