MaterialFX VS RichTextFX

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

RichTextFX isn't great -- documentation is generally unhelpful and not much development lately. I've also found bugs in the component and figuring my way around internals is hard for a new-ish Kotlin dev.

RichTextFX is very much Some Assembly Required and there isn't much documentation. I would definitely say it's not easy to use IMHO. I'm currently working on creating a word processing control with it, but it's still very much a work in progress. If you go the route of using RichTextFX, the repo might help you figure some things out.

RichTextFX provides decent syntax highlighting for JavaFX. The project is barely active but works great nevertheless.

RichTextFX issue

This is a tough one. JavaFX doesn't currently have that capability. This would involve a lot of font metrics and line metrics calculations. The API currently does not have public methods for such. Might be added in future versions of javafx.

RichTextFX - This fits the bill. It uses following subcomponents..

VirtualizedFX and TextFlow will be key to creating stylized text editor if you decide to venture that direction. A game changer. RichtextFX is the most popular but uses Flowless as a virtualised container for TextFlow display, hence has many dependencies.
