我创建了从 JFrame 继承的通知窗口,但它们在 Windows 任务栏中以新图标出现。是否可以在通知出现时突出显示主应用程序图标(例如在 Skype 中,当有新消息时)并且不在通知窗口的任务栏中显示新图标?
这是弹出的代码:
public class NotificationWindow extends JFrame
{
/**
*
*/
private static final long serialVersionUID = 1L;
static private int m_count = 0;
public NotificationWindow(String text)
{
super("NotificationWindow");
setLayout(new GridBagLayout());
setSize(300, 70);
setLocationRelativeTo(null);
setOpacity(0.77f);
setUndecorated(true);
setResizable(false);
add(new JLabel(text));
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent evt)
{
--m_count;
}
});
++m_count;
}
static public int GetWindowCount()
{
return m_count;
}
static public void ShowNotificationWindow(final String text)
{
// Determine if the GraphicsDevice supports translucency.
GraphicsEnvironment graphicsEnvironment = GraphicsEnvironment
.getLocalGraphicsEnvironment();
final GraphicsDevice graphicsDevice = graphicsEnvironment
.getDefaultScreenDevice();
// If translucent windows aren't supported, exit.
if (!graphicsDevice.isWindowTranslucencySupported(TRANSLUCENT))
{
System.err.println("Translucency is not supported");
System.exit(0);
}
JFrame.setDefaultLookAndFeelDecorated(true);
// Create the GUI on the event-dispatching thread
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run()
{
NotificationWindow notificationWindow = new NotificationWindow(
text);
Insets scnMax = Toolkit.getDefaultToolkit().getScreenInsets(
notificationWindow.getGraphicsConfiguration());
int taskBarSize = scnMax.bottom;
Rectangle rect = graphicsDevice.getDefaultConfiguration()
.getBounds();
int x = (int) rect.getMaxX() - notificationWindow.getWidth();
int y = (int) rect.getMaxY() - notificationWindow.getHeight()
- taskBarSize - ((m_count - 1) % 7)
* notificationWindow.getHeight();
notificationWindow.setLocation(x, y);
notificationWindow.setVisible(true);
}
});
}
}
