java 如何将 Swing 应用程序转换为 Applet？

How to convert a Swing Application to an Applet?

提问by fromvega

I created a desktop application with Swing Application Framework, now how can I convert it to an applet? The main class extends SingleFrameApplication.

我使用 Swing 应用程序框架创建了一个桌面应用程序，现在如何将其转换为小程序？主类扩展了 SingleFrameApplication。

EDITED: This is the starting class, used NetBeans GUI builder:

编辑：这是起始类，使用 NetBeans GUI 构建器：

public class PhotoApp extends SingleFrameApplication {

    /**
     * At startup create and show the main frame of the application.
     */
    @Override protected void startup() {
        show(new PhotoView(this));
    }

    /**
     * This method is to initialize the specified window by injecting resources.
     * Windows shown in our application come fully initialized from the GUI
     * builder, so this additional configuration is not needed.
     */
    @Override protected void configureWindow(java.awt.Window root) {
    }

    /**
     * A convenient static getter for the application instance.
     * @return the instance of PhotoUploaderApp
     */
    public static PhotoApp getApplication() {
        return Application.getInstance(PhotoApp.class);
    }

    /**
     * Main method launching the application.
     */
    public static void main(String[] args) {
        launch(PhotoApp.class, args);
    }
}

The quick and dirty way:

快速而肮脏的方式：

Drop extends SingleFrameApplication. Add extends JApplet.

Drop 扩展了 SingleFrameApplication。添加扩展 JApplet。

replace the constructor with public void init() leaving the body as is.

用 public void init() 替换构造函数，使主体保持原样。

Create an HTML page to hold it. and give it a whirl.

创建一个 HTML 页面来保存它。试一试。

There will likely be some scoping issues, but you should be able to fix those fairly easily.

可能会有一些范围界定问题，但您应该能够很容易地解决这些问题。

Simplest thing is just to make a new outer class inheriting from JApplet, and instantiate the actual frame inside it.

最简单的事情就是创建一个新的从 JApplet 继承的外部类，并在其中实例化实际的框架。
