JavaJavaFX在MouseOver上闪烁(最近重新绘制)并带有集成Swing

我尝试将javaFX应用程序集成到Swing应用程序中,并成功地完成了

但问题是,我无法解决鼠标悬停在按钮上时javaFX相关面板闪烁(重新绘制速度太慢)的问题

有没有解决方案,或者我会尝试将Swing集成到javaFX中?这会很烦人

private void initFX(JFXPanel fxPanel) throws IOException {
    // This method is invoked on the JavaFX thread
    scene = createScene();
    fxPanel.setScene(scene);
}

public MainFrame()  {

    Panel container = new Panel();
    container.setLayout(null);
    try {
        final JFXPanel panel = new JFXPanel();
        Insets insets = container.getInsets();
        container.add(panel);

        JApplet mapApplet = (JApplet)Class.forName("samples.mainApp.MainApplet").newInstance();
        container.add(mapApplet); //Display Applet
        add(container);

        mapApplet.setBounds(800, 0, 566, 720);
        panel.setBounds(0, 0, 800, 720);

        mapApplet.init();
        mapApplet.start();  

        Platform.runLater(new Runnable() {
            @Override
            public void run() {
                try {
                    initFX(panel);
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
       });
    } catch (InstantiationException | IllegalAccessException
            | ClassNotFoundException e) {
        e.printStackTrace();
    }
    //button.setVisible(false);
    catch (Exception e) {
        e.printStackTrace();
    }
}
private Scene createScene() throws IOException {
            root = new  Group();
            scene  =  new  Scene(root, Color.ALICEBLUE);
            Button btn1 = new Button("Connect");
            root.getChildren().addAll(btn1);

    But the problem is, I cannot resolve the problem that javaFX related panel is flashing(repainting so slow) when mouseover a button.

    Is there any solution, or will I try to integrate Swing into javaFX? Which will be annoying

    • 从未见过这种情况,也从未出现过闪烁(不知道如何运行,从您发布的代码中模拟)

    • 为了获得更好的帮助,请尽快发布一个SSCCE/MCVE,简短、可运行、可编译、由a.m.引起并描述了问题(请注意测试并查看SwingUtilities.invokeLaterPlatform.runLater的用法)
