===== Csak dupla kattintás =====

Dupla kattintás figyelése egy ListView elemen. 

<code java ValamiController.java>
import javafx.fxml.FXML;
import javafx.scene.input.MouseButton;
import javafx.scene.input.MouseEvent;

public class UserController {

  @FXML
  private ListView<String> userList;

  @FXML
  private void onListDoubleClick(MouseEvent e)  {    
    if(
        e.getButton().equals(MouseButton.PRIMARY) && 
        e.getClickCount() == 2) {
      System.out.println("Dupla");
    }
  }
}

===== Dupla kattintásra listaelem =====

Dupla kattintás figyelése egy ListView elemen.

===== Egy és dupla kattintás szétválasztva =====

<code java ValamiController.java>
import java.io.IOException;

import javafx.animation.PauseTransition;
import javafx.fxml.FXML;
import javafx.scene.control.ListView;
import javafx.scene.control.TextField;
import javafx.scene.input.MouseButton;

import javafx.util.Duration;

public class UserController {
  PauseTransition pause = new PauseTransition(Duration.millis(500));

  @FXML
  private ListView<String> userList;

  @FXML
  private TextField editField;

  public UserController() {
    pause.setOnFinished(e -> {
      System.out.println("kattintott");
    });
  }

  @FXML
  private void onListDoubleClick(MouseEvent e)  {
    if (e.isPrimaryButtonDown() && e.getClickCount() == 1) {
       pause.play();
    }
    if (e.isPrimaryButtonDown() && e.getClickCount() == 2) {
      pause.stop();
      System.out.println("dupla");
    }
  }
