How to strip formating on paste? (rich text box)

[darkflame]

I'm using a rich text area, and Ive run into the problem that when
users cut and paste from some applications, a lot of junk formating is
pasted as well.

Is there any method to catch the paste, and strip this data out?
So, while users can use it for rich text editing, they can only paste
data in as plane text.

RichTextArea extends FocusWidget, which has a number of handlers for
keyboard events.
This snippet will let you catch a paste, assuming that the users paste
using CTRL+V

RichTextArea area = new RichTextArea();
area.addKeyDownHandler(new KeyDownHandler() {
@Override
public void onKeyDown(KeyDownEvent event) {
if (event.isControlKeyDown() && event.getNativeKeyCode() == 86) {
System.out.println("Paste");
}
}
});

Not sure how you would catch the paste event if it came from a right-
click context menu
or the browser menu though...

Thanks, thats 1/3rd of the problem solved then ;)
Guess I'll need to write a routine that strips all formating except
for bold,italic,underline, links etc.
Probably need to use a regex. grr. I always get muddled with them.
