在JApplet上分层对象(扩展JComponet) [英] Layering Objects (That extend JComponet) on JApplet

问题描述

我目前有一个JApplet，其中添加了两个都扩展JComponet的对象. 对象A基本上是一个大正方形，而对象B是一个小正方形，我需要对象B始终位于对象A的前面，但是我无法解决如何在JApplet中设置分层的方法. 当前，我正在使用以下代码，该代码将两个项目都添加并显示它们，但是有时对象A位于对象B的前面.

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();
}

推荐答案

您可能会看到 JLayeredPane ，见此处，或OverlayLayout，见混合方法可能会提供更多的灵活性.

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.
