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`
