MaterialFX VS rich-text-area

You can have a look at the VirtualizedFX which is a virtual flow that is written from scratch and inspired by Flowless. The author Palexdev (I think the person is on reddit), took inspiration from Flowless, and has documented the code quite well. You can have a look and also implement a virtual grid with it such as a GridView. Honestly, I tried making my virtual flow, that is simple with a few classes as possible (with adequate success), and the inspiration came from it. The VirtualizedFX has now been incorporated in MaterialFX which is another main project by the same author.

Probably MaterialFX, but I haven't worked with it yet.

Unfortunately I'd like to say I have implemented them in my MaterialFX library but I still haven't done it Definitely on the ROADMAP though

You can check the full change list here: Changelog

You can also check out MaterialFX, the MFXTextField has an inbuilt feature to limit the characters

Currently, I use Flowless in my main project, MaterialFX and I really like its performance, its cells' concept, but it has some serious flaws:

There's a way to calculate the minimum required width so that the text is not truncated. Check this utility in my JavaFX library: MaterialFX, LabelUtils

I could add the control to my project MaterialFX, but I recently did a huge update and currently I'm taking a little pause as usual. If you can wait you gave me a good idea and I can definitely add an auto complete field in the ROADMAP list. I can't give any ETA though

Not bad, well done but... Did you know that there's a successor to JFoenix? Take a look at my library here MaterialFX

Gluon's RichTextArea is GPL 3 (not ideal for my project), bugs abound, and hasn't been touched in a year.

Actually, there is Have you ever wondered why JavaFX controls are made in Java code and not FXML, even custom ones (like this here from Gluon)
