> Incubating a new feature - rich text control, **RichTextArea**, intended to bridge the functional gap with Swing and its StyledEditorKit/JEditorPane. The main design goal is to provide a control that is complete enough to be useful out-of-the box, as well as open to extension by the application developers.
> 
> This is a complex feature with a large API surface that would be nearly impossible to get right the first time, even after an extensive review. We are, therefore, introducing this in an incubating module, **jfx.incubator.richtext**. This will allow us to evolve the API in future releases without the strict compatibility constraints that other JavaFX modules have.
> 
> Please check out two manual test applications - one for RichTextArea (**RichTextAreaDemoApp**) and one for the CodeArea (**CodeAreaDemoApp**). Also, a small example provides a standalone rich text editor, see **RichEditorDemoApp**.
> 
> Because it's an incubating module, please focus on the public APIs rather than implementation.  There **will be** changes to the implementation once/if the module is promoted to the core by popular demand.  The goal of the incubator is to let the app developers try the new feature out.
