Lets you pass a value to the component
when you use it in an item renderer or item editor.
You typically use data binding to bind a field of the data
property to a property of this component.
When you use the control as a drop-in item renderer or drop-in
item editor, Flex automatically writes the current value of the item
to the text property of this control.
You cannot set this property in MXML.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the dataChange event.
Implementation
public function get data():Object public function set data(value:Object):voidSee also
domWindow | property |
domWindow:Object [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
The JavaScript window object
for the root frame of the HTML DOM inside this control.
This property is null until the
htmlDOMInitialize event has been dispatched.
The default value is null.
Implementation
public function get domWindow():Object historyLength | property |
historyLength:int [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |

including back and forward entries.
This property has the same value
as the window.history.length
JavaScript property of the the HTML content.
Implementation
public function get historyLength():intSee also
historyPosition | property |
historyPosition:int| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
The current position in the history list.
The history list corresponds to the window.history
object of the HTML content.
Entries less than the current position are the "back" list;
entries greater are "forward."
Attempting to set the position beyond the end sets it to the end.
The default value is 0.
Implementation
public function get historyPosition():int public function set historyPosition(value:int):void htmlHost | property |
htmlHost:flash.html:HTMLHost| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |

to certain user interface elements in the HTML content,
such as the window.document.title property.
To override default behaviors for the HTMLLoader, create a subclass of the HTMLHost class, override its member functions to handle various user interface changes in the HTML content, and set this property to an instance of your subclass.
The default value is null.
Implementation
public function get htmlHost():flash.html:HTMLHost public function set htmlHost(value:flash.html:HTMLHost):void htmlLoader | property |
public var htmlLoader:flash.html:HTMLLoader| Language Version: | ActionScript 3.0 |

| Runtime Versions: | AIR 1.1 |
The IFactory that creates an HTMLLoader-derived instance to use as the htmlLoader.
The default value is an IFactory for HTMLLoader.
This property can be used as the source for data binding. When this property is modified, it dispatches the htmlLoaderFactoryChanged event.
Implementation
public function get htmlLoaderFactory():IFactory public function set htmlLoaderFactory(value:IFactory):void htmlText | property |
htmlText:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
Specifies an HTML-formatted String for display by the control.
Setting this property has the side effect of setting
the location property to null,
and vice versa.
Content added via the htmlText property is put in the
application security sandbox. If an AIR application includes an HTML
control located in the application sandbox, and remote HTML code is
directly added into the control by setting the htmlText
property, any script contained in the HTML text is executed in the
application sandbox.
The default value is "".
This property can be used as the source for data binding. When this property is modified, it dispatches the htmlTextChanged event.
Implementation
public function get htmlText():String public function set htmlText(value:String):voidSee also

of the component with the appropriate data from the List control.
The component can then use the listData property
to initialize the data property of the drop-in
item renderer or drop-in item editor.
You do not set this property in MXML or ActionScript; Flex sets it when the component is used as a drop-in item renderer or drop-in item editor.
The default value is null.

loaded | property |
loaded:Boolean [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
A flag which indicates whether the JavaScript load event
corresponding to the previous loading operation
has been delivered to the HTML DOM in this control.
This property is true
before the complete event is dispatched.
It is possible that this property
never becomes true.
This happens in the same cases
in which the complete event is never dispatched.
The default value is false.
Implementation
public function get loaded():Boolean location | property |
location:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
The URL of an HTML page to be displayed by this control.
Setting this property has the side effect of setting
the htmlText property to null,
and vice versa.
The default value is "".
This property can be used as the source for data binding. When this property is modified, it dispatches the locationChange event.

paintsDefaultBackground | property |
paintsDefaultBackground:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
Whether this control's HTML content has a default opaque white background or not.
If this property is false,
then the background specified for this Flex control, if any,
appears behind the HTML content.
However, if any HTML element has its own opaque background color (specified by style="background-color:gray", for instance), then that background appears behind that element.
The default value is false;.
Implementation
public function get paintsDefaultBackground():Boolean public function set paintsDefaultBackground(value:Boolean):void pdfCapability | property |
pdfCapability:int [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
The type of PDF support on the user's system, defined as an integer code value.
An HTML object can display PDF content only if this property
evaluates to PDFCapability.STATUS_OK.
The PDFCapability class defines constants for possible values
of the pdfCapability property, as follows:
| PDFCapability constant | Meaning |
|---|---|
STATUS_OK | A sufficient version (8.1 or later) of Acrobat Reader
is detected and PDF content can be loaded in an HTML object.
Note: On Windows, if a Acrobat Acrobat
or Acrobat Reader version 7.x or above
is currently running on the user's system,
that version is used even if a later version
that supports loading PDF loaded in an HTML object is installed.
In this case, if the the value of the
|
ERROR_INSTALLED_READER_NOT_FOUND | No version of Acrobat Reader is detected. An HTML object cannot display PDF content. |
ERROR_INSTALLED_READER_TOO_OLD | Acrobat Reader has been detected, but the version is too old. An HTML object cannot display PDF content. |
ERROR_PREFERED_READER_TOO_OLD | A sufficient version (8.1 or later) of Acrobat Reader is detected, but the the version of Acrobat Reader that is setup to handle PDF content is older than Reader 8.1. An HTML object cannot display PDF content. |
Implementation
public static function get pdfCapability():int runtimeApplicationDomain | property |
runtimeApplicationDomain:ApplicationDomain| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
The ApplicationDomain to use for HTML's window.runtime
scripting.
If this property is null, or if it specifies
an ApplicationDomain from a different security domain
than the HTML content, the HTML page uses a default
ApplicationDomain for the page's domain.
The default value is null.
Implementation
public function get runtimeApplicationDomain():ApplicationDomain public function set runtimeApplicationDomain(value:ApplicationDomain):void userAgent | property |
userAgent:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
The user agent string to be used in content requests from this control.
You can set the default user agent string used by all
HTML controls in an application domain by setting the
static URLRequestDefaults.userAgent property.
If no value is set for the userAgent property
(or if the value is set to null),
the user agent string is set to the value of
URLRequestDefaults.userAgent.
If neither the userAgent property
of this control nor for URLRequestDefaults.userAgent,
has a value set, a default value is used as the user agent string.
This default value varies depending on the runtime
operating system (such as Mac OS or Windows),
the runtime language, and the runtime version,
as in the following two examples:
"Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) AdobeAIR/1.0"
"Mozilla/5.0 (Windows; U; en) AppleWebKit/420+ (KHTML, like Gecko) AdobeAIR/1.0"
The default value is null.

Event Object Type:
property Event.type =
flash.events.Eventproperty Event.type =
flash.events.Event.COMPLETE| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
Dispatched after the last loading operation caused by
setting the location or htmlText
property has completed.
This event is always dispatched asynchronously,
after the JavaScript load event
has been dispatched in the HTML DOM.
An event handler for this event may call any method
or access any property of this control
or its internal htmlLoader.
Event.COMPLETE constant defines the value of the type property of a complete event object.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The network object that has completed loading. |

flash.events.Eventproperty Event.type =
flash.events.Event.HTML_DOM_INITIALIZE| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | AIR 1.1 |
Dispatched after the HTML DOM has been initialized
in response to a loading operation caused by
setting the location or htmlText property.
When this event is dispatched,
no JavaScript methods have yet executed.
The domWindowand domWindow.document
objects exist, but other DOM objects may not.
You can use this event to set properties
onto the domWindow and domWindow.document
objects for JavaScript methods to later access.
A handler for this event should not set any properties or call any methods which start another loading operation or which affect the URL for the current loading operation; doing so causes either an ActionScript or a JavaScript exception.
TheEvent.HTML_DOM_INITIALIZE constant defines the value of the type property
of an htmlDOMInitialize event object.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false; there is no default behavior to cancel. |
currentTarget | The HTMLLoader object. |
target | The HTMLLoader object. |

Because an HTML control can dispatch many of these events,
you should avoid significant processing in a render
handler that might negatively impact performance.
Event.HTML_RENDER constant defines the value of the type property of an htmlRender event object.
This event has the following properties:
