仅在Swing应用程序中使用JavaFX触摸事件

本文介绍了仅在Swing应用程序中使用JavaFX触摸事件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 有没有办法在swing应用程序中使用JavaFX触摸事件？目前我正在使用JFXPanel捕获JavaFX事件，但是当我尝试获取事件时，我不会接收任何触摸事件而只接收鼠标事件。这是在Windows 8.1 Dell触摸屏上测试的。Is there a way to use the JavaFX touch events in a swing application? Currently I am using a JFXPanel to capture the JavaFX events, however when I try to get the events I am not receving any touch events and only mouse events instead. This is tested on a Windows 8.1 Dell Touch Screen. 更新：以下代码是我用来获取事件的框架。此JFXPanel用作Swing应用程序中的glasspane。这为glasspane创建了一个JFXPanel，它能够捕获所有事件。Updated: The code below is the skeleton of what I am using to get the events. This JFXPanel is used as a glasspane in the Swing application. This creates a JFXPanel for the glasspane, which is able to capture all the events.public class MouseEventRouter extends JFXPanel { ... public ZeusMouseEventRouter(JMenuBar menuBar, Container contentPane) { ... this._contentPane = contentPane; this._contentPane.add(_JFXpanel); this._contentPane.setVisible(true); init(); } private void init() { pane = new VBox(); pane.setAlignment(Pos.CENTER); Platform.runLater(this::createScene); } private void createScene() { Scene scene = new Scene(pane); ... scene.setOnTouchPressed(new EventHandler<javafx.scene.input.TouchEvent>() { @Override public void handle(javafx.scene.input.TouchEvent event) { System.out.println("tap down detected"); } }); ... setScene(scene); }}推荐答案 FX邮件列表上的这个问题表明它是不可能使用你采用的方法，而是你需要创建一个JavaFX阶段并使用SwingNode（Swing in FX）而不是JFXPanel（Swing中的FX）嵌入你的Swing应用程序。This question on the FX mailing list suggests it is not possible using the approach you've taken, instead you'll need to create a JavaFX stage and embed your Swing application using SwingNode (Swing in FX) instead of JFXPanel (FX in Swing).我没有任何支持触控的硬件来测试这个，但我希望以下工作能够正常运行......I've not got any touch enabled hardware to test this, but I expect the following to work...public class TouchApp extends Application { public static void main(String[] args) { launch(args); } @Override public void start(Stage primaryStage) throws Exception { JPanel swingContent = new JPanel(); swingContent.add(new JButton("Hello world")); swingContent.add(new JScrollBar()); BorderPane content = new BorderPane(); SwingNode swingNode = new SwingNode(); swingNode.setContent(swingContent); content.setCenter(swingNode); Scene scene = new Scene(content); scene.setOnTouchPressed((e) -> { System.out.println(e); }); primaryStage.setScene(scene); primaryStage.show(); }} 这篇关于仅在Swing应用程序中使用JavaFX触摸事件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
