How to add a custom action to a decorated text?

[joehei]

I would like to highlight some text like a hyperlink, but instead of opening the link something different should happen when clicked on it.

How can this be done? Is there an example?

Many thanks

richtextArea.setLinkCallbackFactory(link -> {
    System.out.println("Do your custom action.");
    return null; // No further action is needed
});
