问题描述
我正在使用Netbeans开发Java应用程序,我想在系统任务栏上创建一个任务栏图标,当我右键单击任务栏图标时将显示一个弹出菜单.
I'm using Netbeans to develop a Java application and I want to create a tray icon at system tray and a popup menu will be display when I right click on tray icon.
我通过拖放创建了一个jframe和弹出菜单.
I have created a jframe and popup menu by drop and drap them.
但是我有一个问题.我的弹出菜单有2个菜单项(退出和显示登录名),但是选中的菜单项没有突出显示,并且在单击菜单后项目,弹出菜单未关闭.
But I have a problem.My popup menu have 2 menu items (Exit and Show Login) but selected menu item is not high-lighted and after I click menu item, popup menu is not closed.
这是我的代码:
声明一些全局变量
SystemTray systemTray = null;
Image image = Toolkit.getDefaultToolkit().getImage("D:/key-16x16.png");
TrayIcon trayIcon = new TrayIcon(image);
创建并显示系统任务栏图标
Create and display system tray icon
systemTray = SystemTray.getSystemTray();
try
{
systemTray.add(trayIcon);
} catch (AWTException ex)
{
Logger.getLogger(mainframe.class.getName()).log(Level.SEVERE, null, ex);
}
创建MouseAdapter并为任务栏图标添加mouseListener
Create MouseAdapter and add mouseListener for tray icon
MouseAdapter trayIconMouseAdapter = new MouseAdapter()
{
// @Override
public void mouseClicked(MouseEvent e) {
trayIconMouseClicked(e);
}
};
trayIcon.addMouseListener(trayIconMouseAdapter);
处理托盘图标上的鼠标单击事件.检查是否右键单击并显示弹出菜单
handle mouse click event on tray icon. Check whether it is a right click and show popupmenu
private void trayIconMouseClicked(java.awt.event.MouseEvent evt) {
if(SwingUtilities.isRightMouseButton(evt))
{
popupMeunu.show(evt.getComponent(), evt.getX(), evt.getY());
}
}
但是如果我将按钮悬挂到jframe并用 popupMeunu.show替换
一切都会好的. popupMeunu.show(evt.getComponent(),evt.getX(),evt.getY());
(jButton1,evt.getX(),evt.getY());
But if i drap a button to jframe and replace popupMeunu.show(evt.getComponent(), evt.getX(), evt.getY());
by popupMeunu.show(jButton1, evt.getX(), evt.getY());
everything will be OK.
我不知道为什么?请帮助我解决问题.
I don't know why?Pls help me to slove my problem.
推荐答案
不要添加自己的MouseListener.
Don't add your own MouseListener.
在...的构造函数中传递您的 popupMeunu
(需要是 java.awt.PopupMenu
,而不是 javax.swing.JPopupMenu
).像这样的 TrayIcon
:
Pass your popupMeunu
(which needs to be a java.awt.PopupMenu
, not javax.swing.JPopupMenu
) in the constructor of TrayIcon
like that:
TrayIcon trayIcon = new TrayIcon(image, "The Tip Text", popup);
我从教程复制了此文件,并且效果很好.
I copied this from this tutorial and it worked fine.
