哑光边框具有"哑光"外观。假设以下是我们的组件减号
JLabel label;
label = new JLabel("This has matte border!");
让我们使用 BorderFactory 类创建哑光边框。在这里，我们使用 Color 类赋予颜色黄色 −
label.setBorder(BorderFactory.createMatteBorder(3, 5, 10, 5, Color.YELLOW));
以下是创建哑光边框的示例 −
示例
package my;
import javax.swing.BorderFactory;
import java.awt.Color;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class SwingDemo {
public static void main(String[] args) throws Exception {
JFrame frame = new JFrame("Demo");
JLabel label;
label = new JLabel("This has matte border!");
label.setFont(new Font("Arial", Font.BOLD, 18));
label.setVerticalAlignment(JLabel.CENTER);
label.setBorder(BorderFactory.createMatteBorder(3, 5, 10, 5, Color.YELLOW));
frame.add(label);
frame.setSize(550,350);
frame.setVisible(true);
}
}
输出
