IntelliJ IDEA Windowbuilder 创建的 Java Swing 错误/错误

Question

我使用 IntelliJ IDEA 15 并创建了这个窗口。 它是一个 Java swing 应用程序。

1. 我的 GUI 显示了这个错误。我不知道为什么。我尝试重新绘制/重新验证/验证，但没有任何帮助。

如果我改变鼠标位置，错误就会跟随

2. 为什么我的背景是黑色的？在这里你可以看到错误。

请帮帮我

主要的启动方法

public class Launch {
    public static void main(String[] args) throws URISyntaxException {
        WebLookAndFeel.install();
        Main main = new Main();
        main.setUndecorated(true);
        main.setVisible(true);
        main.pack();
    }
}

这是我的构造函数

public Main() throws URISyntaxException {
    setRealFeel();
    setContentPane(mainPanel);
    setMinimumSize(new Dimension(400, 300));
    setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
    Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
    setLocation(((dim.width / 2) - 200), ((dim.height / 2) - 150));
    ComponentResizer cr = new ComponentResizer();
    cr.registerComponent(this);
    cr.setSnapSize(new Dimension(10, 10));
    cr.setMinimumSize(new Dimension(400, 300));
    mainMenu.setVisible(false);
    loadingPanel.setVisible(false);
    this.mainFrame = this;
