標題:
JPanel 類別與 setBorder() 方法
試使用 setBorder() 方法,為容器加上邊框。
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JPanel;
import java.awt.GridLayout;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;
public class Ch117 {
JPanel pn1,pn2,pn3;
JButton btn[]=new JButton[4];
JFrame fm;
Ch117()
{
for(int i=0; i<4; i++)
btn[i]=new JButton("按鈕"+(i+1));
pn1=new JPanel();
pn1.setBorder(new EtchedBorder());
pn2=new JPanel();
pn2.setBorder(new TitledBorder("第二區"));
pn3=new JPanel();
pn3.setBorder(new TitledBorder(null,"第三區",TitledBorder.CENTER,TitledBorder.BOTTOM));
pn3.setLayout(new GridLayout(4,1,5,5));
for(int i=0; i<4; i++)
pn3.add(btn[i]);
fm=new JFrame("JPanel & setBorder()");
fm.setBounds(100, 100, 450, 300);
fm.setVisible(true);
fm.setResizable(true);
fm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
fm.setLayout(new GridLayout());
fm.add(pn1);
fm.add(pn2);
fm.add(pn3);
}
public static void main(String[] args) {
new Ch117();
}
}
