How to hide scrollbar in QScrollArea?

Question

How can one hide the scrollbars in a QScrollArea? Currently I use the hide() method on the scrollbars returned by QScrollArea::horizontalScrollBar() and QScrollArea::verticalScrollBar() but the space reserved for scrollbars still remains. Obviously this looks very ugly and is not space efficient. If I remove the scrollbars altogether I can no longer easily scroll to a specific point using QScrollBar::setValue().

Answer 1

You can hide it using a style sheet. Use height:0px; to hide the horizontal scroll bar and width=0px; to hide the vertical scroll bar. Like that:

horizontalScrollBar()->setStyleSheet("QScrollBar {height:0px;}");
verticalScrollBar()->setStyleSheet("QScrollBar {width:0px;}");

And voila!.No scroll bars, and you can still manipulate them using setValue().

Use this code:

QAbstractScrollArea::setHorizontalScrollBarPolicy( Qt::ScrollBarAlwaysOff )
QAbstractScrollArea::setVerticalScrollBarPolicy( Qt::ScrollBarAlwaysOff )
