Hi.
I am having some troubles to change the thickness of the silders in a QScrollArea. The goal is to use it with a touch screen.

I have already tried some things like:

- scrollArea->verticalScrollBar()->setFixedWidth(50);
- scrollArea->verticalScrollBar()->setMinimumWidth(50);

The result is just that the small arrows are not well displayed but the thickness of the slider remains very small.

Does somebody have an idea to do it?

Thank you very much!
