removeDropTarget

public DropTarget removeDropTarget(DropTarget dropTarget)

Removes the given drop target from anywhere within the tree of CascadedDropTargets. If the given dropTarget is an immediate child of this CascadedDropTarget (CDT), then the other child is returned. Otherwise, a reference to this CDT will be returned with the given dropTarget having been removed from one of this CDT's children. This method effectively removes the given dropTarget from the hierarchy and collapses the tree structure as needed.

Parameters:

dropTarget - The target to remove

Returns:

the new drop target reference
