How to create a JFrame within a Java applet or vice versa
提问by Roland Sams
I am trying to create a Java applet with JInternalFrames. For this I believe you need a JFrame in one form or another. I heard you could wrap your applet in a JFrame, is that best? If you could tell me what I should do I would appreciate it. TYIA -Roland
我正在尝试使用 JInternalFrames 创建一个 Java 小程序。为此，我相信您需要一种或另一种形式的 JFrame。我听说您可以将小程序包装在 JFrame 中，这样最好吗？如果你能告诉我该怎么做，我将不胜感激。TYIA-罗兰

You can create JFrame in the applet code same way you do in a stand alone Swing application:
您可以在小程序代码中创建 JFrame，方法与在独立 Swing 应用程序中相同：
JFrame frame = new JFrame("Hello");
....
frame.show();
The frame will leave the browser window, showing up as a separate window, just it will contain some warning tags that this is a Java applet running. Such frame can be resized or moved around.
该框架将离开浏览器窗口，显示为一个单独的窗口，只是它会包含一些警告标记，表明这是一个 Java 小程序正在运行。这样的框架可以调整大小或四处移动。
Actually, some "applets" do not show much more than a single button to launch the frame in they main view.
实际上，一些“小程序”在它们的主视图中只显示一个按钮来启动框架。
See http://baba.sourceforge.net/for an example of the applet that shows four buttons to launch four different visualizations (source code is available).
请参阅http://baba.sourceforge.net/以获取显示四个按钮以启动四种不同可视化效果的小程序示例（源代码可用）。
If, very differently, you actually want frames that could not leave your applet area, use InternalFrame. It is a LayeredPane so you can also put your main component as a background layer.
如果非常不同，您确实想要无法离开您的小程序区域的框架，请使用InternalFrame。它是一个 LayeredPane，因此您还可以将主要组件作为背景层。
