Class XbpScrollBar() Foundation
Class function of the XbpScrollBar class.
The XbpScrollBar class provides objects that display and manage horizontal and vertical scroll bars. This dialog element is often used when all of the data to be displayed cannot be shown within a window. The scroll bars are used to scroll the drawing area of the window so that hidden data becomes visible in the window area.
A scroll bar consists of four elements that allow interaction: two scroll buttons at each end, a movable scroll box and a scroll bar where the scroll box is moved. Depending on which part of the scroll bar is clicked, different actions are performed. The :scroll callback code block or the :scroll() callback method is used to react to user interaction with the scroll bar and processes the current position of the scroll box.
Scroll bars are passive dialog elements. If the scroll box is operated using the mouse, the scroll bar object does not receive the input focus. Instead, the input focus remains on the Xbase Part that was active before the scroll bar object was manipulated. To explicitly set the input focus to an XbpScrollbar object, the function SetAppFocus() must be used.
The instance variables in this group configure system resources. If changes are made to these values, they must either be made before the :create() method is executed or the :configure() method must be used to activate the changes.
