Question

好的，所以我试图熟悉将侦听器添加到对象中，并且我会尝试修改我的一个应用程序，让它在调整窗格大小后重新定位图像，就像它在示例中显示的那样....工作....只有在这个项目中，当我尝试执行同样的事情时，我得到了这个例外：

Exception in Application constructor
Exception in thread "main" java.lang.NoSuchMethodException: MouseEvent.MouseEventDemo.main([Ljava.lang.String;)
    at java.lang.Class.getMethod(Class.java:1773)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:119)

我使用的代码在这里：

// Add a listener to relocate object upon pane resize
        pane.widthProperty().addListener(ov -> {
            circularText.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
            imageView2.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
        });

        pane.heightProperty().addListener(ov -> {
            circularText.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
            imageView2.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
        });

好吧，我是一个白痴，显然这不是因为我添加了听众，这是因为我创建了一个新项目来放置我的文件而我选择了错误的类型XD

此外，我最后一个问题是打开我的上一个项目，因为安装了avast！并运行我的第一个quickscan病毒扫描程序锁定我的计算机导致我强制关闭并导致.idea中的workspace.xml文件损坏...删除它并重新打开项目并重新运行该程序似乎解决它

Javafx并在窗口调整大小时重新定位图像？
