isDropSite

public boolean isDropSite(SimpleNodeInterface[] dragNodePath,
                          SimpleNodeInterface[] dropNodeParentPath,
                          int index)

Description copied from interface: TreeDnDDelegateInterface

Indicates whether a node is dropable on another node.

Specified by:

isDropSite in interface TreeDnDDelegateInterface

Parameters:

dragNodePath - complete path to and including the node to be dragged

dropNodeParentPath - complete path to and including the node to be dropped on

index - position in the 0-based child list of the node described by dropNodePath in which to insert the node described by dragNodePath. The value -1 can be specified to append the node being dragged to the child list of the node being dropped on.

Returns:

true if the node specified by dropNodePath allows the node specified by dragNodePath to be dropped on it, false otherwise

performDrop

public boolean performDrop(SimpleNodeInterface[] dragNodePath,
                           SimpleNodeInterface[] dropNodeParentPath,
                           int position)

Description copied from interface: TreeDnDDelegateInterface

Drops one node on another at position. A position of -1 can be specified to append the node being dragged to the child list of the node being dropped on.

Specified by:

performDrop in interface TreeDnDDelegateInterface

Parameters:

dragNodePath - complete path to and including the node being dragged

position - The position in the 0-based child list of the node described by dropNodePath in which to insert the node described by dragNodePath. The value -1 can be specified to append the node being dragged to the child list of the node being dropped on

Returns:

true if the drop operation was successfully performed, false otherwise
