我如何安排此appletform？我试图在我的小程序中添加menuitems但没有运气！如果单击关闭menuitem，如何关闭窗口？我试过dispose（）;但它也没有用！

public class AppletForm extends Applet implements
    DragGestureListener, // For recognizing the start of drags
    DragSourceListener, // For processing drag source events
    DropTargetListener, // For processing drop target events
    MouseListener, // For processing mouse clicks
    MouseMotionListener // For processing mouse drags
{
    private MenuBar menuBar = new MenuBar(); // first, create a MenuBar item
    private Menu file = new Menu(); // our File menu
    // what's going in File? let's see...
    private MenuItem openFile = new MenuItem();  // an open option
    private MenuItem saveFile = new MenuItem(); // a save option
    private MenuItem close = new MenuItem(); // and a close option!

    StringBuffer strBuffer;

    public void init() {
        setSize(500, 300);
    addMouseListener(this);
    strBuffer = new StringBuffer();
        addItem("initializing the apple ");

    }
}

如何设置applet的标题？

类似的东西：

<head> <title>The Applet Title</title> </head>

我正在尝试在我的applet中添加menuitems而没有运气！

试一试：

MenuBar mbar = new MenuBar();
Menu m = new Menu("File");
m.add(new MenuItem("New"));
m.add(new MenuItem("Open"));
m.addSeparator();
m.add(new MenuItem("Save"));
m.add(new MenuItem("Save As"));
m.addSeparator();
m.add(new MenuItem("Print"));
m.addSeparator();
m.add(new MenuItem("Quit"));
mbar.add(m);

Menu m = new Menu("Edit");
m.add(new MenuItem("Undo"));
m.add(new MenuItem("Redo"));
m.addSeparator();
m.add(new MenuItem("Cut"));
m.add(new MenuItem("Copy"));
m.add(new MenuItem("Delete"));
m.add(new MenuItem("Paste"));
m.addSeparator();

Menu f = new Menu("Options");
f.add(new CheckboxMenuItem("Insert"));
f.add(new CheckboxMenuItem("Auto indent"));
m.add(f);
mbar.add(m);

Menu m = new Menu("Help");
m.add(new MenuItem("Index"));
m.add(new MenuItem("About"));
mbar.add(m);

setMenuBar(mbar);

如果单击关闭menuitem，如何关闭窗口？

试一试：

public void exit() {     
    setVisible(false);
    dispose();
    System.exit(0);
}
