下面的示例演示了如何在Java Swing应用程序中创建带有Icon和Text的按钮。
使用以下API -
JButton()- 创建标准按钮。ImageIcon()- 创建图像图标。JButton(ImageIcon)- 使用Icon创建一个Button。JButton.setText()- 在按钮中设置文本。
示例
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.LayoutManager;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import javax.swing.AbstractButton;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class SwingTester {
public static void main(String[] args) {
createWindow();
}
private static void createWindow() {
JFrame frame = new JFrame("Swing Tester");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
createUI(frame);
frame.setSize(560, 200);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
private static void createUI(final JFrame frame){
JPanel panel = new JPanel();
LayoutManager layout = new FlowLayout();
panel.setLayout(layout);
ImageIcon arrowIcon = null;
java.net.URL imgURL = SwingTester.class.getResource("arrow.jpg");
if (imgURL != null) {
arrowIcon = new ImageIcon(imgURL);
} else {
JOptionPane.showMessageDialog(frame, "Icon image not found.");
}
JButton iconButton = new JButton(arrowIcon);
iconButton.setText("Next");
iconButton.setToolTipText("Move Ahead");
iconButton.setVerticalTextPosition(AbstractButton.CENTER);
iconButton.setHorizontalTextPosition(AbstractButton.LEADING);
iconButton.setMnemonic(KeyEvent.VK_I);
iconButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(frame, "Icon Button clicked.");
}
});
panel.add(iconButton);
frame.getContentPane().add(panel, BorderLayout.CENTER);
}
}
执行上面示例代码，得到以下结果：
