How to clear the scolling text widget ?

...

Hello !...

I'm working on new projects : addition in column.

As I want the answers to be right aligned, I don't use TEB* but the "scrolling text" widget.

But I realize that the learners could write a very long answer in it, so I want to add a button to clear the answer, and didn't manage to do it on the same screen.

Do you have a solution ?

Thanks !...

(*That's a shame that we haven't more options on the TEB ???...)
