Tip Tip
This is the only valid way to create a window vertical scroll bar.
A WindowVerticalScrollBar object is a special type of scroll bar that is aligned along the right side of a window's canvas area. It resizes itself according to the size of the window that owns it. After creating a WindowVerticalScrollBar object, it should then be shown and its range set.
Examples
This example enables a WindowVerticalScrollBar object and sets its range to be 1-200, with a block size of 25:
X#
Copy
1METHOD Init() CLASS TopAppWindow
2pwvs := SELF:EnableVerticalScroll()
3pwvs:Show()
4pwvs:Range := Range{1,200}
5pwvs:BlockSize := 25
