Layering Objects (That extend JComponet) on JApplet

问题

I currently have a JApplet within which I add two objects that both extend JComponet. Object A is basically a large square and object B is a small square, I need Object B to always be in front of Object A, however I cant work out how to set layering within the JApplet to do this. Current I am using the follow code, which adds both the items and displays them how I want however sometimes Object A is front of Object B.

public void init() {
    add(myapplet, BorderLayout.CENTER);
    resize(200, 400);
    B = new Block(Color.green, 10, 10);
    myapplet.add(B);
    A = new Block(Color.red, 100, 100);
    myapplet.add(A);
    myapplet.addMouseListener(this);
    startTimer();
}

回答1:

You might look at JLayeredPane, seen here, or OverlayLayout, seen here. Either should work in an applet, but this hybrid approach may offer additional flexibility.

You may want to look at this method: Container.setComponentZOrder(Component comp, int index)
