How to I wrap text in a Tooltip with javafx?

Question

I have an ArrayList that I am trying to get into a Tooltip when the mouse hovers over a Node. I have everything set, but I can't figure out how to wrap text in the Tooltip in order to display each item in the ArrayList on a separate line in the Tooltip.

Answer 1

Solution which does not rely on the deprecated TooltipBuilder:

Tooltip tooltip = new Tooltip(str);
tooltip.setPrefWidth(100);
tooltip.setWrapText(true);

Answer 2

You have to define 2 different properties, a prefWidth for your tooltip and set wrapTextProperty property to true.

Your code will somewhat look like this

Tooltip t = TooltipBuilder.create().text(str).prefWidth(100).wrapText(true).build();
