Remarks
There are two types of horizontal scroll bars in X#: regular (created with CLASS HorizontalScrollBar) and window (created with the AppWindow:EnableHorizontalScroll() method). Both types have an owner window and can be manipulated using Window:HorizontalScroll(). However, a window horizontal scroll bar differs in that it automatically appears aligned along the bottom of its owner window's canvas area and also resizes itself according to the size of its owner window.
 Tip |
|---|
| By default, Window:HorizontalScroll() updates the thumb position in the scroll bar; if desired, you can change this by using your own implementation of this handler. |
