property UseScrollRegion : Boolean
Defines whether the scrolling region is active.
If UseScrollRegion is False, the scrolling region is inactive and writes of text and scrolling apply to the whole screen. If UseScrollRegion is True, the scrolling region is in force and all screen changes are limited to the scrolling region.
Calling SetScrollRegion automatically forces this property to True, the new scrolling is brought into effect immediately.
