Language Version: ActionScript 3.0

The SpaceJustifier class represents properties that control the justification options for text lines in a text block.

Use the constructor new SpaceJustifier() to create a SpaceJustifier object before setting its properties. Setting the properties of a SpaceJustifier object after you apply it to a TextBlock does not invalidate the TextBlock.
