When a Spark RichEditableText is created,
its accessibilityImplementation property
is set to an instance of this class.
The Flash Player then uses this class to allow MSAA clients
such as screen readers to see and manipulate the RichEditableText.
See the mx.accessibility.AccImpl and
flash.accessibility.AccessibilityImplementation classes
for background information about accessibility implementation
classes and MSAA.
Children
A RichEditableText has no MSAA children.
Role
The MSAA Role of a RichEditableText is ROLE_SYSTEM_TEXT.
Name
The MSAA Name of a RichEditableText is, by default, the empty string.
When wrapped in a FormItem element, the Name is the FormItem's label.
To override this behavior,
set the RichEditableText's accessibilityName property.
When the Name changes, a RichEditableText dispatches the MSAA event EVENT_OBJECT_NAMECHANGE.
Description
The MSAA Description of a RichEditableText is, by default,
the empty string, but you can set the RichEditableText's
accessibilityDescription property.
State
The MSAA State of a RichEditableText is a combination of:
- STATE_SYSTEM_UNAVAILABLE (when enabled is false)
- STATE_SYSTEM_FOCUSABLE (when enabled is true)
- STATE_SYSTEM_FOCUSED (when enabled is true and the RichEditableText has focus)
- STATE_SYSTEM_PROTECTED (when displayAsPassword is true)
- STATE_SYSTEM_READONLY (when editable is false)
When the State changes, a RichEditableText dispatches the MSAA event EVENT_OBJECT_STATECHANGE.
Value
The MSAA Value of a RichEditableText is equal to
its text property.
When the Value changes, a RichEditableText dispatches the MSAA event EVENT_OBJECT_VALUECHANGE.
Location
The MSAA Location of a RichEditableText is its bounding rectangle.
Default Action
A RichEditableText does not have an MSAA DefaultAction.
Focus
A RichEditableText accepts focus. When it does so it dispatches the MSAA event EVENT_OBJECT_FOCUS.
Selection
A RichEditableText does not support selection in the MSAA sense,
and text selection is not part of Microsoft's IAccessibility COM interface.
But, in Player 10.1 and later, screen readers can determine
the currently selected text range via the GetSelection() method
in Adobe's ISimpleTextSelection COM interface, which calls the
selectionAnchorIndex and selectionActiveIndex
getters in this class.

selectionActiveIndex | 屬性 |
selectionActiveIndex:int [唯讀] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10.1, AIR 2.0 |
A character position, relative to the beginning of the
text String of the RichEditableText,
specifying the end of the selection
that moves when the selection is extended with the arrow keys.
The active position may be either the start or the end of the selection.
For example, if you drag-select from position 12 to position 8,
then selectionAnchorPosition will be 12
and selectionActivePosition will be 8,
and when you press Left-Arrow selectionActivePosition
will become 7.
A value of -1 indicates "not set".
In Player 10.1 and later, and AIR 2.0 and later,
an AccessibilityImplementation can implement
selectionAnchorIndex and selectionAnchorIndex
in order to make an accessibility client aware of the text selection
in TLF text via Adobe's ISimpleTextSelection COM interface.
預設值為 -1。

Enables accessibility in the RichEditableText class.
This method is called by application startup code
that is autogenerated by the MXML compiler.
Afterwards, when instances of RichEditableText are initialized,
their accessibilityImplementation property
will be set to an instance of this class.
