How do I pick up the Enter Key being pressed in JavaFX2?


I have a TextField to enter a search term, and a button for "Go". But in JavaFX2, how would I make it so pressing the Enter Key in the TextField would perform an action?

Thanks :)

You can use the onAction attribute of the TextField and bind it to a method in your controller.

public void onEnter(ActionEvent ae){
   System.out.println("test") ;

And in your FXML file:

<TextField fx:id="textfield" layoutX="29.0" layoutY="298.0" onAction="#onEnter" prefWidth="121.0" />

I'm assuming you want this to happen when the user presses enter only while the TextField has focus. You'll want use KeyEvent out of javafx.scene.input and do something like this...

textField.setOnKeyPressed(new EventHandler<KeyEvent>()
        public void handle(KeyEvent ke)
            if (ke.getCode().equals(KeyCode.ENTER))

Hope this is helpful!
