public class HyperlinkLabel
extends javafx.scene.control.Control
implements javafx.event.EventTarget

A UI control that will convert the given text into a series of text labels and hyperlinks, based on the use of delimiter characters to specify where hyperlinks should appear. The delimiter characters are square braces (that is, [ and ]). To create a hyperlink in a string you would therefore do something like hyperlinkLabel.setText("Click [here] for more information!");, with the word 'here' appearing as a hyperlink that a use may click. This approach therefore allows for hyperlinks to be easily embedded within a label.

Once hyperlinks have been declared in a text string, it is necessary to respond to the user interacting with the hyperlink (most commonly via mouse clicks). To do so, you register a single event handler for action events on the HyperlinkLabel instance, and then determine what to do within that callback. For example:

 
 hyperlinkLabel.setOnAction(new EventHandler<ActionEvent>() {
     public void handle(ActionEvent event) {
         Hyperlink link = (Hyperlink)event.getSource();
         final String str = link == null ? "" : link.getText();
         switch(str) {
             case "here": // do 'here' action
                          break;
             case "exit": // do exit action
                          break;
         }
     }
 });

This simple single-handler approach was chosen over any more complex per-hyperlink solution because it is anticipated that most use cases will normally consist of one, or very few hyperlinks, and it was therefore unlikely that the increased API complexity would be warranted.

Screenshot

To demonstrate what a HyperlinkLabel looks like, refer to the screenshot below, when the text "Hello [world]! I [wonder] what hyperlink [you] [will] [click]" was passed in to the HyperlinkLabel instance:
