Usage
When the user clicks in a horizontal scroll bar, nothing happens
unless you have scripts that change the scroll bar’s Position property.
For the scroll bar arrows, use the LineLeft and LineRight events; for
clicks in the scroll bar background above and below the thumb, use the
PageLeft and Right events; for dragging the thumb itself, use the Moved
event.
Examples
This code in the PageLeft event causes the thumb to move left a
predetermined page size when the user clicks on the left arrow of the
horizontal scroll bar (the page size is stored in the instance variable
ii_pagesize):
|
1 2 3 4 5 6 |
IF This.Position < & This.MinPosition + ii_pagesize THEN This.Position = MinPosition ELSE This.Position = This.Position - ii_pagesize END IF |
