title: How to resize the scrollbar from a QTextEdit in PyQt?
body: <p>I'm using a QTextEdit widget in my python GUI - designed with PyQt4. The vertical scrollbar appears as soon as the text doesn't fit anymore in the QTextEdit widget. But the scrollbar itself is so small (high dpi screen). How can I enlarge the scrollbar, such that clicking and dragging it gets more user friendly?</p>
