MOUSE Events on FX 2.0 not working correctly

Question

Hi,
I am trying to capture mouse right click in my Java FX application to show the ContextMenu but couldn't do so.
There are methods available in the API i.e. isSecondaryButtonDown() and isPrimaryButtonDown on MouseEvents to capture mouse clicks but not working.
Both of the above mention methods return false irrespective of right or left click.
I will be glad to see resolution for it.
Thanks in Advance.

I have no idea what the context of the code you are writing is, but capturing of MouseEvents works fine for me.
Perhaps you are trying to test mouseEvent.isSecondaryButtonDown() in a MOUSE_CLICKED event handler which will correctly return false after a right mouse click because the click event can't be generated until the button is released (i.e. no longer down).
import javafx.application.Application;
import javafx.event.*;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.input.*;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
public class MouseEventTest extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  public void start(final Stage stage) throws Exception {
    // provide some instructions.
    final Label instructions = new Label("Right click anywhere to choose a fruit");
    instructions.setStyle("-fx-font-size: 20;");
    instructions.setMouseTransparent(true);
    // ready a context menu.
    final ContextMenu fruitChoices = new ContextMenu();
    fruitChoices.getItems().addAll(new MenuItem("Apples"), new MenuItem("Oranges"), new MenuItem("Pears"));
    for (final MenuItem menuItem : fruitChoices.getItems()) {
      menuItem.setOnAction(new EventHandler<ActionEvent>() {
        @Override public void handle(ActionEvent actionEvent) {
          instructions.setText("Enjoy your " + menuItem.getText());
          System.out.println("You like " + menuItem.getText());
    // display the context menu whenever a user clicks inside a node.
    final Rectangle node = new Rectangle(400, 300, Color.LIGHTBLUE);
    node.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>() {
      @Override public void handle(MouseEvent mouseEvent) {
        System.out.println(mouseEvent);
        System.out.println("Secondary button down: " + mouseEvent.isSecondaryButtonDown());
        if (MouseButton.SECONDARY.equals(mouseEvent.getButton())) {
          System.out.println("Choosing fruit");
          fruitChoices.show(instructions, mouseEvent.getScreenX(), mouseEvent.getScreenY());
    // show the scene.
    final StackPane layout = new StackPane();
    layout.getChildren().addAll(node, instructions);
    Scene scene = new Scene(layout); 
    stage.setScene(scene);
    stage.show();
}
