TextOperationEvent

Package | spark.events
Class | public class TextOperationEvent
Inheritance | TextOperationEvent flash.events.Event

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | Flash Player 10, AIR 1.5

The TextOperationEvent class represents events that are dispatched when text content changes due to user operations such as inserting characters, backspacing, pasting, or changing text attributes.

This event is dispatched by subclasses of the SkinnableTextBase class. This includes RichEditableText and classes that use RichEditableText such as ComboBox and TextInput, as well as TextArea. Text controls that have no user interaction, such as RichText and Label, do not dispatch events of this type.

Constant Detail

CHANGE | Constant

`public static const CHANGE:String = change`

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | Flash Player 10, AIR 1.5

The `TextOperationEvent.CHANGE` constant defines the value of the `type` property of the event object for a `change` event.

The properties of the event object have the following values:

Property | Value
--- | ---
`bubbles` | false
`cancelable` | false
`currentTarget` | The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`operation` | The FlowOperation object describing the editing operation being performed on the text by the user.
`target` | The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

CHANGING | Constant |

`public static const CHANGING:String = changing`

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | Flash Player 10, AIR 1.5

The `TextOperationEvent.CHANGING` constant defines the value of the `type` property of the event object for a `changing` event.

The properties of the event object have the following values:

Property | Value
--- | ---
`bubbles` | false
`cancelable` | true
`currentTarget` | The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`operation` | The FlowOperation object describing the editing operation being performed on the text by the user.
`target` | The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
