Remarks Tip |
---|
This is the only valid way to create a window horizontal scroll bar. |
A WindowHorizontalScrollBar object is a special type of scroll bar that appears aligned along the bottom of a window's canvas area. It resizes itself according to the size of the window that owns it.
After creating a window horizontal scroll bar, it should then be shown and its range set.
Examples
This example enables a WindowHorizontalScrollBar object and sets its range to 1-80, with a block size of 8:
1METHOD Init() CLASS MyAppWindow
2owhs := SELF:EnableHorizontalScroll(TRUE)
3owhs:Show()
4owhs:Range := Range{1,80}
5owhs:BlockSize := 8
