我正在尝试弄清楚如何在收到新消息时向我的停靠图标添加数字通知(我有一个小型聊天应用程序)
这就是我的意思:
任何想法如何做到这一点?
最佳答案
尝试看一下com.apple.eawt.Application
(我很难找到JavaDocs)
import com.apple.eawt.Application;
import java.awt.EventQueue;
import java.awt.GridBagLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.Timer;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestBadge {
public static void main(String[] args) {
new TestBadge();
}
public TestBadge() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
ex.printStackTrace();
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JLabel label;
private int count;
public TestPane() {
setLayout(new GridBagLayout());
add((label = new JLabel("0")));
Timer timer = new Timer(250, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
count++;
label.setText(Integer.toString(count));
Application.getApplication().setDockIconBadge(Integer.toString(count));
}
});
timer.start();
}
}
}
我应该指出,如果您在能够检查已安装类的IDE中运行,则应该能够获得
Application
类提供的功能列表。我使用的是NetBeans,能够找到所有方法的清单,问题是,有些文件已记录在案,有些则不是:P
