如何在 Java Swing 中使用 EmptyBorder 留出空间

首先，我们创建一个 JPanel 并设置带标题的边框:
JPanel panel = new JPanel();
panel.setBorder(BorderFactory.createTitledBorder("Demo Panel"));
现在创建空边框:
JPanel panel2 = new JPanel(new BorderLayout()); panel2.add(panel, BorderLayout.CENTER); panel2.setBorder(BorderFactory.createEmptyBorder(100, 100, 100, 100));
以下是在 Java Swing 中使用 EmptyBorder 留出空间的示例:
示例
import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class SwingDemo {
public static void main(String[] args) {
JPanel panel = new JPanel();
panel.setBorder(BorderFactory.createTitledBorder("Demo Panel"));
JPanel panel2 = new JPanel(new BorderLayout());
panel2.add(panel, BorderLayout.CENTER);
panel2.setBorder(BorderFactory.createEmptyBorder(100, 100, 100, 100));
panel2.setPreferredSize(new Dimension(700, 350));
JFrame frame = new JFrame("Set Space");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(panel2);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
}
