首先，看看这个用 d3.js 编写的不可思议的例子：http: //mbostock.github.io/d3/talk/20111018/partition.html
我正在尝试在 Java 中模拟类似的东西。我不是很成功。我已经能够创建 GUI，但动画被证明是困难的。在玩了一些非常不成功的事情之后，我想我需要一些指导。
编辑：我不确定如何描述问题，但我会尝试。单击嵌套的 JPanel 时，我想聚焦此面板并展开其中的内容以填充整个窗口。就像您在示例中看到的一样，如果您可以查看的话。例如，当您单击标有“vis”的蓝色块时，该块将聚焦于其下方的所有内容。它非常像一棵树，但有生气。
我想我只是被困在如何以一种能够如所描述的方式设计系统上。我正在寻找解决问题的策略。如果我需要更具体，请告诉我。
package animation;
import java.awt.BorderLayout;
public class TestAnimation extends JFrame {
private boolean buttonActive = false;
private boolean boxActive = false;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
TestAnimation frame = new TestAnimation();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public TestAnimation() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//this.setExtendedState(JFrame.MAXIMIZED_BOTH);
setBounds(100, 100, 450, 300);
getContentPane().setLayout(new BorderLayout());
ParentObj one = new ParentObj("Vblock", this);
}
}
这是实例化的父对象的类：

public class ParentObj extends JComponent{
public boolean isActive = false;
public final JFrame frame;
public Obj1 compute;
public Obj1 storage;
public String name;
public Obj1 test;
public ParentObj(String n, JFrame f){
this.frame = f;
this.name = n;
final JPanel panelL = new JPanel();
panelL.setBackground(Color.blue);
panelL.setLayout(new BorderLayout());
panelL.addMouseListener(new MouseListener(){
public void mouseClicked(MouseEvent e){
System.out.println(name);
//startAnimations(box);
}

}
});
JLabel title = new JLabel(name);
title.setForeground(Color.white);
title.setHorizontalAlignment(SwingConstants.CENTER);
panelL.add(title, BorderLayout.CENTER);
final JPanel panelR = new JPanel();
panelR.setLayout(new GridLayout(0, 1, 0, 0));
panelR.addMouseListener(new MouseListener(){
public void mouseClicked(MouseEvent e){
System.out.println(name);
//startAnimations(box);
}
@Override

}
@Override

}
@Override

// TODO Auto-generated method stub
}
@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
}
});
final JSplitPane panel = new JSplitPane(1, true, panelL, panelR);
panel.setDividerSize(0);
panel.setResizeWeight(0.3);
panel.setBorder(null);
panel.setBorder(new LineBorder(new Color(0, 0, 0)));
frame.add(panel, BorderLayout.CENTER);
compute = new Obj1("Compute", frame ,panelR);
storage = new Obj1("Storage", frame, panelR);
test = new Obj1("Network", frame, panelR);
}
}
最后，个人作品的小班：

}
如果您对如何产生正确的结果有任何建议，或者是否有解决此问题的另一种方法，请告诉我。非常感谢！
