在java中如何设置 JTextField 输入框的凹凸

设置成3D的效果

Answer 1

text.setBorder(BorderFactory.createLoweredBevelBorder()); // 凹边框
text.setBorder(BorderFactory.create...); // 还有很多效果，你可以再多尝试一些。
text.setBorder(BorderFactory.createRaisedBevelBorder()); // 凸边框
其它的Swing组件大多可以使用此方法设置边框样式。

例：
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class TestMain extends JFrame {

public TestMain() {
JTextField text = new JTextField(10);
JPanel pane = new JPanel();
// text.setBorder(BorderFactory.createLoweredBevelBorder());
text.setBorder(BorderFactory.createRaisedBevelBorder());
getContentPane().add(pane);
pane.add(text);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(300, 200);
setLocationRelativeTo(null);
setVisible(true);
}

public static void main(String[] args) {
new TestMain();
}

}
