Question

If the view component of a scrollpane is large enough, scrollbar thumb is small and then it is not properly painted on windows L&F.

It is only an aesthetic problem; the scrollbar functions properly and everything seems to be fine with other L&Fs.

Is there a way to fix that? Maybe somehow to set the minimal width of a thumb?

Answer 1

This works for me (Java 1.7.0_09, Windows 7):

UIManager.put("ScrollBar.minimumThumbSize", new Dimension(32, 32));
