| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The text lines are static and are created using a single format and a single paragraph. The lines are created to fit in the specified bounding rectangle.
The StringTextLineFactory provides an efficient way to create TextLines, since it reuses single TextFlow, ParagraphElement, SpanElement, and ContainerController objects across many repeated invocations. You can create a single factory, and use it again and again. You can also reuse all the parts that are the same each time you call it; for instance, you can reuse the various formats and the bounds.
Note: To create static lines that use multiple formats or paragraphs, or that include inline graphics, use a TextFlowTextLineFactory and a TextFlow object.
Note: The StringTextLineFactory ignores the truncationIndicatorFormat property set in the truncationOptions when truncating text.

createTextLines | () | method |
public function createTextLines(callback:Function):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Creates TextLine objects using the text currently assigned to this factory object.
The text lines are created using the currently assigned text and formats and
are composed to fit the bounds assigned to the compositionBounds property.
As each line is created, the factory calls the function specified in the
callback parameter. This function is passed the TextLine object and
is responsible for displaying the line.
To create a different set of lines, change any properties desired and call
createTextLines() again.
Note that the scroll policies of the factory will control how many lines are generated.
Parameters
callback:Function — The callback function called for each TextLine object created.
|
createTextLines() is called twice using the same phrase. The factory properties are adjusted between calls
to create a "drop shadow" effect.
