Question

I have 2 buttons, one of them is Play, 2nd is Stop. If i click on Play he should be disabled and Stop should be enabled. I'm using Java FX ScreeBuilder 1.0 Why it doesn't work?

package javafxapplication1;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;
import javafx.scene.paint.Stop;
import javax.swing.JButton;
import javax.swing.plaf.basic.BasicOptionPaneUI;
import javafx.scene.control.Button;

public class FXMLDocumentController implements Initializable {
    @FXML
    private Button start;

        @FXML
    private Button stop;

    @FXML
    private void ButtonStart(ActionEvent event) {
        start.setDisable(true);
        stop.setDisable(false);
    }

    @FXML
    private void ButtonStop(ActionEvent event) {
        start.setDisable(false);
        stop.setDisable(true);
    }

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO
    }    

}

Make sure that you have the Button entry in the corresponding .fxml file linked with the method in your controller.

In your case, these entries should look similar the following:

<Button fx:id="start" onAction="#ButtonStart" />
<Button fx:id="stop" onAction="#ButtonStop" />
