| Language version: | ActionScript 3.0 |
Interface for IME (input method editor) clients. Components based on the flash.text.engine package must implement
this interface to support editing text inline using an IME. This interface is not used with TextField objects.
TextLayoutFramework (TLF) uses this interface to support inline IME, so clients using TLF do not need to implement this
interface.
To support inline IME, set the imeClient property of an ImeEvent.IME_START_COMPOSITION event to
an object which implements this interface.
The following terms are often used in the IME related API:
- A conversation is the interchange between the IME and the application. During a conversation, a composition is
updated one or more times and then confirmed by the user.
- A composition identifies the text entered by the user through the IME; including associated input state information
such as the selected range and the extent of any clauses.
- A clause is a range of the composition possibly sharing semantic information, such as indicating whether the input is
in a selected or converted state. A composition contains zero or more clauses.
compositionEndIndex:int [read-only]
| Language version: | ActionScript 3.0 |
The zero-based character index value of the end of the current edit session text (such as
all text in the inline session that is not confirmed to the document).
Implementation
public function get compositionEndIndex():int
compositionStartIndex:int [read-only]
| Language version: | ActionScript 3.0 |
The zero-based character index value of the start of the current edit session text (such as
all text in the inline session that is not confirmed to the document).
Implementation
public function get compositionStartIndex():int
selectionActiveIndex:int [read-only]
| Language version: | ActionScript 3.0 |
The zero-based character index value of the last character in the current selection.
Implementation
public function get selectionActiveIndex():int
selectionAnchorIndex:int [read-only]
| Language version: | ActionScript 3.0 |
The zero-based character index value of the first character in the current selection.
Implementation
public function get selectionAnchorIndex():int
verticalTextLayout:Boolean [read-only]
| Language version: | ActionScript 3.0 |
Indicates whether the text in the component is vertical or not. This property directs the positioning
of the candidate window (such as beside vertical text or below horizontal text).
Implementation
public function get verticalTextLayout():Boolean
public function confirmComposition(text:String = null, preserveSelection:Boolean = false):void
| Language version: | ActionScript 3.0
|
Use this callback to end the inline editing session and confirm the text.
Parameters
| text:String (default = null) |
| |
| preserveSelection:Boolean (default = false) |
public function getTextBounds(startIndex:int, endIndex:int):Rectangle
| Language version: | ActionScript 3.0
|
The IME uses this method to query the bounding box of the text currently edited with the IME client.
Use this method to place the candidate window and set the mouse cursor in the IME client when the mouse is over the
text field or other component that supports IME.
Parameters
| startIndex:int — An integer that specifies the starting location of the range of text from the bounding box you are measuring.
|
| |
| endIndex:int — Optional; an integer that specifies the ending location of the range of text from the bounding box you are measuring.
|
Returns
| Rectangle —
The bounding box of the specified range of text, or null if one or both of the indexes are invalid.
This method returns the same value if startIndex is greater or less than endIndex. The same value should be returned whether or not startIndex is greater or less than endIndex.
|
public function getTextInRange(startIndex:int, endIndex:int):String
| Language version: | ActionScript 3.0 |
Gets the specified range of text from the component. This method is called during IME reconversion.
Parameters
| startIndex:int — an integer that specifies the starting location of the range of text to be retrieved.
|
| |
| endIndex:int — an integer that specifies the ending location of the range of text to be retrieved.
|
Returns
| String —
The requested text, or null if no text is available in the requested range
or if either or both of the indexes are invalid. The same value should be returned
independant of whether startIndex is greater or less than endIndex.
|
public function selectRange(anchorIndex:int, activeIndex:int):void
| Language version: | ActionScript 3.0 |
Sets the range of selected text in the component.
If either of the arguments is out of bounds the selection should not be changed.
Parameters
| anchorIndex:int — The zero-based index value of the character at the anchor end of the selection
|
| |
| activeIndex:int — The zero-based index value of the character at the active end of the selection.
|
public function updateComposition(text:String, attributes:Vector.<CompositionAttributeRange>, compositionStartIndex:int, compositionEndIndex:int):void
| Language version: | ActionScript 3.0
|
Callback for updating the contents of the inline editing session.
This method is called whenever the text being edited with the IME has changed
and its contents are used by the client to redraw the entire inline editing session.
Parameters
| text:String — Contains the text of the inline edit session from the IME.
|
| |
| attributes:Vector.<CompositionAttributeRange> — Contains an array of composition clauses with adornment info.
|
| |
| compositionStartIndex:int — Start of the inline session relative to the start of the text object.
|
| |
| compositionEndIndex:int — End of the inline session relative to the start of the text object.
|
Event object type: flash.events.IMEEvent
IMEEvent.type property = flash.events.IMEEvent.IME_START_COMPOSITION
| Language version: | ActionScript 3.0 |
Dispatched when the user begins to use an IME (input method editor).
Event object type: flash.events.TextEvent
TextEvent.type property = flash.events.TextEvent.TEXT_INPUT
| Language version: | ActionScript 3.0 |
Dispatched when the user enters text. For IME (input method editor) clients, the receiver should
insert the string contained in the event object's text property at the current insertion point.
Defines the value of the type property of a textInput event object.
Note: This event is not dispatched for the Delete or Backspace keys.
This event has the following properties:
| Property | Value |
|---|
bubbles | true |
cancelable | true; call the preventDefault() method
to cancel default behavior. |
currentTarget | The object that is actively processing the Event
object with an event listener. |
target | The text field into which characters are being entered.
The target is not always the object in the display list
that registered the event listener. Use the currentTarget
property to access the object in the display list that is currently processing the event. |
text | The character or sequence of characters entered by the user. |
