| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
TextFlow() constructor when you create a new TextFlow
instance. It allows the application to initially control how the Text Layout Framework behaves.
The Configuration class allows you to specify initial, paragraph and container formats for the text flow
through the textFlowInitialFormat property. It also allows you to specify initial format attributes for links, selection,
scrolling, and for handling the Tab and Enter keys.

focusedSelectionFormat | property |
focusedSelectionFormat:SelectionFormat| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The initial selection format (SelectionFormat) for a text flow (TextFlow) when its window has focus.
Text Layout Framework uses focusedSelectionFormat to draw the selection when the window is active and one of
the containers in the TextFlow has focus. You can override this format using
SelectionManager.focusedSelectionFormat, if desired.
The SelectionFormat class specifies the default values, which invert the color of the text and its background.
Implementation
public function get focusedSelectionFormat():SelectionFormat public function set focusedSelectionFormat(value:SelectionFormat):voidRelated API Elements
inactiveSelectionFormat | property |
inactiveSelectionFormat:SelectionFormat| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The initial selection format (SelectionFormat) for a text flow (TextFlow) when its window is inactive. Text Layout Framework uses
inactiveSelectionFormat for drawing the selection when the window is inactive. You can override
this format using SelectionManager.inactiveSelectionFormat, if desired.
If you do not override unfocusedSelectionFormat the SelectionFormat values used are:
color = 0xffffff(white)alpha = 0blendMode = flash.display.BlendMode.DIFFERENCE
The result is no selection is displayed.
Implementation
public function get inactiveSelectionFormat():SelectionFormat public function set inactiveSelectionFormat(value:SelectionFormat):voidRelated API Elements
inlineGraphicResolverFunction | property |
inlineGraphicResolverFunction:Function| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies the callback used for resolving an inline graphic element.
The callback takes a flashx.textLayout.elements.InlineGraphicElement object and returns
the value to be used as the element's flashx.textLayout.elements.InlineGraphicElement#source.
This callback provides the mechanism to delay providing an inline graphic element's source until just before it is composed.
Note: this callback will be invoked only if a placeholder source of String type is already set. Moreover, it may be invoked multiple times.
Implementation
public function get inlineGraphicResolverFunction():Function public function set inlineGraphicResolverFunction(value:Function):voidRelated API Elements

Default value is true.
Implementation
public function get manageEnterKey():Boolean public function set manageEnterKey(value:Boolean):voidmanageTabKey | property |
manageTabKey:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |

Implementation
public function get overflowPolicy():String public function set overflowPolicy(value:String):voidRelated API Elements
releaseLineCreationData | property |
releaseLineCreationData:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |

Configuration | () | Constructor |
public function Configuration(initializeWithDefaults:Boolean = true)| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor - creates a default configuration.
ParametersinitializeWithDefaults:Boolean (default = true)true. If set to false, initializes
without default values, thereby saving some objects. The clone() method sets this
to false and copies the properties from the original object.
