Property Detail

allowMerge

property
allowMerge:Boolean

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Indicates whether this operation can be merged with operations executed before or after it.

Some delete operations, for example, a sequence of backspace keystrokes, can be fruitfully merged into one operation so that undoing the operation reverses the entire sequence.



Implementation
    public function get allowMerge():Boolean
    public function set allowMerge(value:Boolean):void

deleteSelectionState

property 
deleteSelectionState:SelectionState

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

deleteSelectionState The range of text to delete



Implementation
    public function get deleteSelectionState():SelectionState
    public function set deleteSelectionState(value:SelectionState):void
Constructor Detail

DeleteTextOperation

()Constructor
public function DeleteTextOperation(operationState:SelectionState, deleteSelectionState:SelectionState = null, allowMerge:Boolean = false)

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Creates a DeleteTextOperation operation.

Parameters
operationState:SelectionState — The original range of text.
 
deleteSelectionState:SelectionState (default = null) — The range of text to delete, if different from the range described by operationState. (Set to null to delete the range described by operationState.)
 
allowMerge:Boolean (default = false) — Set to true if this operation can be merged with the next or previous operation.
