Constructor Detail

MoveChildrenOperation | () | Constructor

`public function MoveChildrenOperation(operationState:SelectionState, source:FlowGroupElement, sourceIndex:int, numChildren:int, destination:FlowGroupElement, destinationIndex:int)`

Language Version : | ActionScript 3.0

Runtime Versions : | Flash Player 10, AIR 1.5

Creates a MoveChildrenOperation object.

This operation moves a consecutive number of children of source into the destination context. Also, if moving the children leaves the source element with no children, then source will be removed. The removal is done recursively such that if source's parent becomes empty from the removal of source, it too will be deleted, and on up the parent chain.

Parameters

| `operationState:SelectionState` — Specifies the SelectionState of this operation
| `source:FlowGroupElement` — Specifies the parent of the item(s) to move.
| `sourceIndex:int` — Specifies the index of the first item to move.
| `numChildren:int` — Specifies the number of children to move.
| `destination:FlowGroupElement` — Specifies the new parent of the items.
| `destinationIndex:int` — Specifies the new child index of the first element.
