如何将 BorderFactory 类中的 EtchedBorder 设置为 Java 中的组件?
从 BorderFactory 类设置 EtchedBorder −
EtchedBorder etchedBorder = (EtchedBorder)BorderFactory.createEtchedBorder();
现在,为组件设置 -
JButton button = new JButton("Etched Border"); button.setBorder(etchedBorder);
以下是一个示例,从 BorderFactory 类中设置组件的 EtchedBorder -
示例
package my; import java.awt.BorderLayout; import java.awt.Container; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.border.Border; import javax.swing.border.EtchedBorder; public class SwingDemo { public static void main(String args[]) { JFrame frame = new JFrame("Demo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Border raisedBorder = new EtchedBorder(EtchedBorder.RAISED); EtchedBorder etchedBorder = (EtchedBorder)BorderFactory.createEtchedBorder(); JButton raisedButton = new JButton("Raised Border"); raisedButton.setBorder(raisedBorder); JButton button = new JButton("Etched Border"); button.setBorder(etchedBorder); Container contentPane = frame.getContentPane(); contentPane.add(raisedButton,BorderLayout.NORTH); contentPane.add(button,BorderLayout.EAST); frame.setSize(600, 300); frame.setVisible(true); } }
