Be open minded. This is a cross platform library with several features: - Text drawing engine. - Text layout engine. - BBCode parser. - Two custom views that connect everything: BBCodeView - multiline, scrollable with support for embedded views. BBLabel - lightweight label. - NEW...
I don't know if I understand correctly. But it looks like several custom views of TextView editable with confirmation button.
If I understand correctly you can find several in the forum but it would be easy to create it as a custom view. (see here)
The solutions in the link are just adding a textfield and a button to a pane and adjusting the positions. albeit not in javafx. So a customview would make that straightforward.
That's exactly the solution, how it is implemented depends how you want it to look. Moving it inside or over the textfield makes it look like one control.
