Thanks again, David.
My problem was that I was looking (in the quick reference) only in
widget_control keywords for widget_text. I forgot to see widget_control
keywords for ALL widgets. :(
I saw your suggestion to avoid setting screen size, but the case is that I
want to build a saving tool. And the question here is how to navigate in the
directories. So the number of strings (the files) will be different from
directory to directory and the size of the main window is constant. I'm
assuming that for what I want scrolling the widget_text is inevitable. Is
that it?
This reminds me of another question. Since I have a widget_base realized is
there a way do remove or add components (like buttons)? I think I tried once
to make an event where a button is added and then "realize" the widget_base
again but I guess it didn't work.
Cheers,
Nuno.
