我必须在下面的 GUI 中添加一些要点。以下是我到目前为止所做的代码

import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.File;

JButton bplus, bminus;
double factor = 0.5;
JPanel titlePanel;
JLabel redLabel;
PoiS(){
p = new DrawingPanel();
/*

buttonPlus = new JButton(" Zoom Out ");
buttonMinus.addActionListener(this);
buttonPlus.addActionListener(this);
Box box = Box.createHorizontalBox();
box.add(Box.createHorizontalGlue());
box.add(buttonMinus);
box.add(Box.createHorizontalStrut(20));
box.add(buttonPlus);
box.add(Box.createHorizontalGlue());
add(box, BorderLayout.SOUTH);

and another class
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import javax.swing.BorderFactory;
import javax.swing.JPanel;
/**

*/
class DrawingPanel extends JPanel {
double squareSize[] = {100.0, 50.0};
double factor = 0.5;
DrawingPanel() {
super(null);
setBorder(BorderFactory.createLineBorder(Color.RED));
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
Dimension dim = this.getSize();
int width = dim.width - 10;
int height = dim.height - 10;
for(int i = 0; i < squareSize.length; ++i) {
int squareWidth = (int) (squareSize[i] * factor);
int x = (width - squareWidth) / 2;
int y = (height - squareWidth) / 2;
g.drawRect(x, y, squareWidth, squareWidth);
}
}
}
只是忽略那些评论部分作为我的 Netbeans 的复制粘贴
我不想删除，因为我认为我将来可能需要它。我只是想让你帮我在这个框架中绘制另一个 JPanel。任何帮助将不胜感激
