Question: Post append Stylespans

Hey there, i have another question. But first: RichTextFX is a awesome Library and its amazing what you can do with it!

Im my Program, i am doing highlighting the same way as the JavaKeyWord Demo: https://github.com/FXMisc/RichTextFX/blob/master/richtextfx-demos/src/main/java/org/fxmisc/richtext/demo/JavaKeywords.java

Now my question, i want afterwards to add a background color to a line. And i only have the line Number. I tried to get the spans with GenericStyleArea#getStyleSpans(int paragraph) and then append it with the StyleSpans#append method, sadly this did not work at all, after i saw that the append method is returning the spans, i tried to re set these spans to the paragraph in the area, sadly also didnt work(infact there was a case where i ran into a stackoverflow Exception).

So my question: What is the proper way to add style to a specific line with style spans. (If i missed the point in the Documentation which explains that, i would be very happy if you could provide me with a link to it).

I’m having some difficulty in understanding what you’re trying to do.

It sounds like, somewhere in the method where you compute the StyleSpans for highlighting, that you would like to overlay another style on top of a section in the StyleSpans object. Is that correct? In other words, you’re not trying to append a style to the end of the StyleSpans object, so that it now is longer than before. You’re trying to do something like the following, which would imply overlay, correct?

text \n text text text text \n text text text
| ----- computed highlighting ---- |
       | background color  | // also add a background color "on top of" the regular styles

Which subclass of GenericStyledArea are you using?

Hmm… I started to update the demo to use that and now I’m getting a recursive update like what you described. I’d guess that #695 has potentially introduced a regression.
