RichParagraph.Builder has public RichParagraph.Builder addWavyUnderline(int start, int length, Color color) method.
However, I can't find a way how to make a wavy underline via CSS. It is very important for me because I want to make all styling via CSS - I don't want to make users use different mechanisms for styling (CSS, code). Fox example, RichTextFX contains the following rules: /* the color of the underline */ -rtfx-underline-color: <paint>; /* the radius used to create waved underline */ -rtfx-underline-wave-radius: <size>; Could anyone say how to do it in JFX RichTextArea?
