java 8object oriented programmingprogramming
对于按钮边框，请使用 Java 中的 createLineBorder() 方法，该方法还允许您设置边框的颜色:
JButton button = new JButton("Demo Button!");
Border border = BorderFactory.createLineBorder(Color.BLUE);
以下是在 Java 中更改按钮边框的示例:
示例
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.border.Border;
public class SwingDemo {
public static void main(String args[]) {
JFrame frame = new JFrame("Button Border");
Container container = frame.getContentPane();
JButton button = new JButton("Demo Button!");
Border border = BorderFactory.createLineBorder(Color.BLUE);
button.setBorder(border);
container.add(button, BorderLayout.CENTER);
frame.setSize(550, 300);
frame.setVisible(true);
}
}
输出
