Scrollbars are useful while looking at large documents or images that cannot appear in a limited visible area. Scrollbars appear horizontally or vertically, indicating your current position in the document or image and the size of the region that is not visible. Using the slider handle provided with these bars, you can access the hidden part of the document or image.
Sliders are a way of selecting an integer value between two values. That is, a slider can represent a minimum and maximum range of values, and the user can select a value within this range by moving the slider handle to the desired location in the slider.
Scrollbars are used for viewing documents or images that are larger than the view area. To display horizontal or vertical scrollbars, you use the HorizontalScrollBar
and VerticalScrollBar
widgets, which are instances of the QScrollBar
class. These scrollbars have a slider handle that can be moved to view the area that is not visible....
