如何在 Java 中设置框架中的所有箭头按钮？

要为框架设置箭头按钮，我们首先创建一个框架 -

JFrame frame = new JFrame();

现在，设置框架的布局，其中将显示所有箭头按钮 -

frame.setLayout(new GridLayout(0,5));

为所有位置设置箭头按钮 -

frame.add(new BasicArrowButton(BasicArrowButton.EAST));
frame.add(new BasicArrowButton(BasicArrowButton.NORTH));
frame.add(new BasicArrowButton(BasicArrowButton.SOUTH));
frame.add(new BasicArrowButton(BasicArrowButton.WEST));

以下是在框架中设置所有箭头按钮的一个例子 -

例子

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);
   }
}
