FlexHTMLLoader

Package | mx.core
Class | public class FlexHTMLLoader
Inheritance | FlexHTMLLoader flash.html.HTMLLoader
Implements | IFocusManagerComplexComponent, IIMESupport

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

FlexHTMLLoader is a subclass of the Player's HTMLLoader class used by the Flex HTML control. It overrides the `toString()` method to return a string indicating the location of the object within the hierarchy of DisplayObjects in the application.

Public Properties

| Property | Defined By
--- | --- | ---
|  | enableIME : Boolean [read-only] A flag that indicates whether the IME should be enabled when the component receives focus. | FlexHTMLLoader
|  | focusEnabled : Boolean A flag that indicates whether the component can receive focus when selected. | FlexHTMLLoader
|  | hasFocusableChildren : Boolean A flag that indicates whether child objects can receive focus. | FlexHTMLLoader
|  | imeMode : String This is just a stub to support the interface. | FlexHTMLLoader
|  | mouseFocusEnabled : Boolean Whether the component can receive focus when clicked on. | FlexHTMLLoader
|  | tabFocusEnabled : Boolean A flag that indicates whether child objects can receive focus This is similar to the tabEnabled property used by the Flash Player. This is usually true for components that handle keyboard input, but some components in controlbars have them set to false because they should not steal focus from another component like an editor. | FlexHTMLLoader

Property Detail

enableIME | property

`enableIME:Boolean` [read-only]

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | Flash Player 10, AIR 1.5

A flag that indicates whether the IME should be enabled when the component receives focus.

Implementation
`public function get enableIME():Boolean`

focusEnabled | property |

`focusEnabled:Boolean`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

A flag that indicates whether the component can receive focus when selected.

As an optimization, if a child component in your component implements the IFocusManagerComponent interface, and you never want it to receive focus, you can set `focusEnabled` to `false` before calling `addChild()` on the child component.

This will cause the FocusManager to ignore this component and not monitor it for changes to the `tabFocusEnabled`, `tabChildren`, and `mouseFocusEnabled` properties. This also means you cannot change this value after `addChild()` and expect the FocusManager to notice.

Note: It does not mean that you cannot give this object focus programmatically in your `setFocus()` method; it just tells the FocusManager to ignore this IFocusManagerComponent component in the Tab and mouse searches.

Implementation
`public function get focusEnabled():Boolean`
`public function set focusEnabled(value:Boolean):void`

hasFocusableChildren | property |

`hasFocusableChildren:Boolean`

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | AIR 1.5

A flag that indicates whether child objects can receive focus.

Note: This property is similar to the `tabChildren` property used by Flash Player. Use the `hasFocusableChildren` property with Flex applications. Do not use the `tabChildren` property.

This property is usually `false` because most components either receive focus themselves or delegate focus to a single internal sub-component and appear as if the component has received focus. For example, a TextInput control contains a focusable child RichEditableText control, but while the RichEditableText sub-component actually receives focus, it appears as if the TextInput has focus. TextInput sets `hasFocusableChildren` to `false` because TextInput is considered the component that has focus. Its internal structure is an abstraction.

Usually only navigator components, such as TabNavigator and Accordion, have this flag set to `true` because they receive focus on Tab but focus goes to components in the child containers on further Tabs.

The default value is `false`, except for the spark.components.Scroller component. For that component, the default value is `true`.

The default value is `false`.

This property can be used as the source for data binding.

Implementation
`public function get hasFocusableChildren():Boolean`
`public function set hasFocusableChildren(value:Boolean):void`

imeMode | property |

`imeMode:String`

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | AIR 1.5

This is just a stub to support the interface. The parent mx.controls.HTML contains the conversionMode and applies it.

Implementation
`public function get imeMode():String`
`public function set imeMode(value:String):void`

mouseFocusEnabled | property |

`mouseFocusEnabled:Boolean`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

Whether the component can receive focus when clicked on. If `false`, focus will be transferred to the first parent that is `mouseFocusEnable` set to `true`.

The default value is `true`.

Implementation
`public function get mouseFocusEnabled():Boolean`
`public function set mouseFocusEnabled(value:Boolean):void`

tabFocusEnabled | property |

`tabFocusEnabled:Boolean`

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | AIR 1.5

A flag that indicates whether child objects can receive focus

This is similar to the `tabEnabled` property used by the Flash Player.

This is usually `true` for components that handle keyboard input, but some components in controlbars have them set to `false` because they should not steal focus from another component like an editor.

The default value is `true`.

This property can be used as the source for data binding.

Implementation
`public function get tabFocusEnabled():Boolean`
`public function set tabFocusEnabled(value:Boolean):void`
Constructor Detail

FlexHTMLLoader | () | Constructor

`public function FlexHTMLLoader()`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

Constructor.

Sets the `name` property to a string returned by the `createUniqueName()` method of the mx.utils.NameUtils class.

This string is the name of the object's class concatenated with an integer that is unique within the application, such as `"FlexLoader13"`.

flash.display.DisplayObject.name
mx.utils.NameUtils.createUniqueName()
Method Detail

assignFocus | () | method

`public function assignFocus(direction:String):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

Called by the FocusManager when the component receives focus. The component may in turn set focus to an internal component. The component's `setFocus()` method will still be called when focused by the mouse, but this method will be used when focus changes via the keyboard.

Parameters

| `direction:String` — one of flash.display.FocusDirection

drawFocus | () | method |

`public function drawFocus(isFocused:Boolean):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

Called by the FocusManager when the component receives focus. The component should draw or hide a graphic that indicates that the component has focus.

Parameters

| `isFocused:Boolean` — If `true`, draw the focus indicator, otherwise hide it.

setFocus | () | method |

`public function setFocus():void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

Called by the FocusManager when the component receives focus. The component may in turn set focus to an internal component.

toString | () | method |

`override public function toString():String`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | AIR 1.1

Returns a string indicating the location of this object within the hierarchy of DisplayObjects in the Application. This string, such as `"MyApp0.HBox5.FlexLoader13"`, is built by the `displayObjectToString()` method of the mx.utils.NameUtils class from the `name` property of the object and its ancestors.

Returns

| `String` — A String indicating the location of this object within the DisplayObject hierarchy.
