The TextLineFactoryBase class serves as the base class for the Text Layout Framework text line factories.

Note: Application code does not typically need to create or use a TextLineFactoryBase object directly. Use one of the derived text factory classes instead.

Property Detail

compositionBounds

property
compositionBounds:Rectangle

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The rectangle within which text lines are created.



Implementation
    public function get compositionBounds():Rectangle
    public function set compositionBounds(value:Rectangle):void

horizontalScrollPolicy

property 
horizontalScrollPolicy:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies how lines are created when the composition bounds are not large enough.

If set to ScrollPolicy.ON or ScrollPolicy.AUTO, all lines are created. It is the your responsibility to scroll lines in the viewable area (and to mask lines outside this area, if necessary). If set to ScrollPolicy.OFF, then only lines that fit within the composition bounds are created.

If the truncationOptions property is set, the scroll policy is ignored (and treated as ScrollPolicy.OFF).



Implementation
    public function get horizontalScrollPolicy():String
    public function set horizontalScrollPolicy(value:String):void

isTruncated

property 
isTruncated:Boolean  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Indicates whether text was truncated when lines were last created.



Implementation
    public function get isTruncated():Boolean

swfContext

property 
swfContext:ISWFContext

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The ISWFContext instance used to make FTE calls as needed.

By default, the ISWFContext implementation is this FlowComposerBase object. Applications can provide a custom implementation to use fonts embedded in a different SWF file or to cache and reuse text lines.



Implementation
    public function get swfContext():ISWFContext
    public function set swfContext(value:ISWFContext):void

See also

truncationOptions

property 
truncationOptions:flashx.textLayout.factory:TruncationOptions

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies the options for truncating the text if it doesn't fit in the composition bounds.



Implementation
    public function get truncationOptions():flashx.textLayout.factory:TruncationOptions
    public function set truncationOptions(value:flashx.textLayout.factory:TruncationOptions):void

verticalScrollPolicy

property 
verticalScrollPolicy:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Specifies how lines are created when the composition bounds are not large enough.

If set to ScrollPolicy.ON or ScrollPolicy.AUTO, all lines are created. It is the your responsibility to scroll lines in the viewable area (and to mask lines outside this area, if necessary). If set to ScrollPolicy.OFF, then only lines that fit within the composition bounds are created.

If the truncationOptions property is set, the scroll policy is ignored (and treated as ScrollPolicy.OFF).
