public void DoAutoScroll( 
   Point modelPnt
)

Parameters

modelPnt

the current mouse point, in model coordinates

As soon ComputeAutoScrollPosition returns a new DiagramPanel.Position value, this method starts a Timer that waits for AutoScrollDelay milliseconds. After waiting, it repeatedly sets DiagramPanel.Position to the latest ComputeAutoScrollPosition value, until the position does not change (presumably because the Diagram's last mouse point is no longer in the autoscroll margin). Setting this view's DiagramPanel.Position occurs each AutoScrollTime milliseconds.

This method is normally called by those tools that want to support auto-scrolling during a mouse move, such as dragging. The timer is stopped when the mouse leaves this view.
