Name

VScroller - scroll an interactor vertically

Remarks:

VScroller is used in VScrollBar and may not be useful otherwise.

VScroller is an interactor that manipulates the perspective of another interactor. This interactor is referred to as the associated interactor. The vscroller is composed of a bar whose position and size reflect the current origin and size in the interactor’s perspective, and a trough in which the bar appears to slide. Clicking and dragging in the vscroller modifies the associated interactor’s perspective. See Scroller(3X) for a description of mouse actions.
