So it looks like you want Button.armed.
But who really knows.



import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class HelloWorld extends Application {

   @Override
   public void start(Stage primaryStage) {
     Button btn = new Button();
     btn.setText("Say 'Hello World'");

     btn.pressedProperty().addListener(new ChangeListener<Boolean>() {
       @Override
       public void changed(ObservableValue<? extends Boolean> observable,
           Boolean oldValue, Boolean newValue) {
         System.out.println("Button Pressed");
       }
     });

     btn.armedProperty().addListener(new ChangeListener<Boolean>() {
       @Override
       public void changed(ObservableValue<? extends Boolean> observable,
           Boolean oldValue, Boolean newValue) {
         System.out.println("Button Armed");
       }
     });

     btn.setOnAction(new EventHandler<ActionEvent>() {

       @Override
       public void handle(ActionEvent event) {
         System.out.println("Hello World!");
       }
     });

     StackPane root = new StackPane();
     root.getChildren().add(btn);

     Scene scene = new Scene(root, 300, 250);

     primaryStage.setTitle("Hello World!");
     primaryStage.setScene(scene);
     primaryStage.show();
   }

   public static void main(String[] args) {
     launch(args);
   }
}
