ComputeEffectiveSelection Method

In This Topic

Produce a new GoSelection that is the real set of objects to be moved by GoView.MoveSelection or copied by GoView.CopySelection.

Syntax

public virtual GoSelection ComputeEffectiveSelection( 
   IGoCollection coll,
   bool move
)

Parameters

coll
move: true for moving, false for copying

Return Value

a GoSelection that is cached as EffectiveSelection

Remarks

This method is used to try to avoid problems with double-moving due to duplicate entries or both a parent and its child being in the argument collection. This also removes objects whose DraggingObject is null or has a false value for CanMove (if is true) or a false value for CanCopy (if is false). Furthermore this adds to the collection all links that have both ports in the selection.
