How to create a textarea with dynamic height with App Designer?

Hi

I'm currently creating a GUI using App Designer. With one button, the user is able to select a file he wants to load. The selected filename should be displayed in a textarea. Because the length of the filenames varies, sometimes the textarea has too many lines and is too big, and sometimes, it has too less and a scrollbar is automatically added.

Is there a way, to make the height of the textarea relative to the length of the string, that has to be displayed?

Thanks in advance -Fabian
