要在框架中设置箭头按钮，我们首先创建一个框架 −
JFrame frame = new JFrame();
现在，设置框架的布局，所有箭头按钮都将显示 −
frame.setLayout(new GridLayout(0,5));
设置所有位置的箭头按钮 −
frame.add(new BasicArrowButton(BasicArrowButton.EAST)); frame.add(new BasicArrowButton(BasicArrowButton.NORTH)); frame.add(new BasicArrowButton(BasicArrowButton.SOUTH)); frame.add(new BasicArrowButton(BasicArrowButton.WEST));
以下示例设置了框架中的所有箭头按钮 −
示例
package my;
import java.awt.GridLayout;
import javax.swing.Box;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.plaf.basic.BasicArrowButton;
public class SwingDemo {
public static void main(String[] args) {
JButton button1 = new JButton("One");
JButton button2 = new JButton("Two");
JButton button3 = new JButton("Three");
JButton button4 = new JButton("Four");
JButton button5 = new JButton("Five");
JButton button6 = new JButton("Six");
Icon icon = new ImageIcon("E:\editicon.PNG");
JButton button7 = new JButton(icon);
Box box = Box.createVerticalBox();
box.add(button1);
box.add(button2);
box.add(button3);
box.add(button4);
box.add(button5);
box.add(button6);
box.add(button7);
JFrame frame = new JFrame();
frame.add(box);
frame.setLayout(new GridLayout(0,5));
frame.add(new BasicArrowButton(BasicArrowButton.EAST));
frame.add(new BasicArrowButton(BasicArrowButton.NORTH));
frame.add(new BasicArrowButton(BasicArrowButton.SOUTH));
frame.add(new BasicArrowButton(BasicArrowButton.WEST));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationByPlatform(true);
frame.setSize(500, 300);
frame.setVisible(true);
}
}
