public class TextLayout
extends TextLines
implements Visualizable
```
The TextLayout class implements the layout of the RichText. The text layout composes the RichText object into multiple paragraphs that are separated by the line end character (RichTextStyle.getLineEndChar()). Each paragraph has its own paragraph style, if the RichTextStyle.multipleParagraphStylesAllowed() is true. The RichText object in the paragraph is composed into multiple lines that are broken at the layout width.
