Questions tagged [qscrollarea]

QScrollArea is a Qt class that provides scrolling functionality to other widgets.

QScrollArea displays the contents of another widget within some frame. If that widget is bigger than the frame and does not fit, scrollbars will be provided so the entire widget can be viewed.

QScrollArea allows changing the scrollbar policies (which determine if the scrollbars are always on, always off, or activated when needed), and to programmatically get and set the scrollbar values.

It also allows customizing the visual appearance of the scrollbars.

Official documentation can be found here.
