一、效果
1、点击“闪烁”按钮可以模拟消息闪动，点击后弹出消息详情对话框；
2、托盘右键菜单包括：“显示”和“关闭”。
3、双击托盘显示程序，关闭后隐藏到托盘。
二、源码
主要代码如下：
1 //初始化托盘
2 void Dialog::InitTray()
3 {
4 QMenu *contexMenu = new QMenu(this); //注意右键菜单的父对象，在窗口销毁后要把菜单也销毁掉
5 QAction *shutAction = new QAction("关闭",this);
6 shutAction->setIcon(QIcon(":/image/close.png"));
7 QAction *showAtion = new QAction("显示",this);
8 showAtion->setIcon(QIcon(":/image/show.png"));
9
10 contexMenu->addAction(shutAction);
11 contexMenu->addSeparator();
12 contexMenu->addAction(showAtion);
13
14 connect(shutAction,SIGNAL(triggered()),this,SLOT(programExit())); //点击了这两个菜单
15 connect(showAtion,SIGNAL(triggered()),this,SLOT(ShowNormal()));
16
17 m_systemTray = new QSystemTrayIcon(this);
18 m_systemTray->setToolTip("Qt 托盘"); //放在图表上时候显示
19 m_systemTray->setContextMenu(contexMenu);
20 m_systemTray->setIcon(QIcon(":/image/qicon.png"));
21 m_systemTray->show();
22 connect(m_systemTray,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,SLOT(trayIconActived(QSystemTrayIcon::ActivationReason)));
23 //connect(m_systemTray, &QSystemTrayIcon::messageClicked, this, &Dialog::ShowMessageBox);
24
25 connect(timerT, &QTimer::timeout, this, &Dialog::sltTimerT);
26 connect(timerNoT, &QTimer::timeout, this, &Dialog::sltTimerNoT);
27 }
28
29
30 //托盘消息闪动
31 void Dialog::on_blingButton_clicked()
32 {
33 timerT->start(300);
34 m_bShowingMsg = true;
35 ui->blingButton->setEnabled(false);
36 ui->noblingButton->setEnabled(true);
37 }
38
39 void Dialog::on_noblingButton_clicked()
40 {
41 if (timerT->isActive())
42 {
43 timerT->stop();
44 }
45
46 if (timerNoT->isActive())
47 {
48 timerNoT->stop();
49 }
50
51 m_bShowingMsg = false;
52 ui->blingButton->setEnabled(true);
53 ui->noblingButton->setEnabled(false);
54
55 m_systemTray->setIcon(QIcon(":/image/qicon.png"));
56 m_systemTray->show();
57 }
58
59 //刷新托盘图标
60 void Dialog::sltTimerT()
61 {
62 m_systemTray->setIcon(QIcon(":/image/qicon.png"));
63 timerNoT->start(300);
64 if(timerT->isActive())
65 {
66 timerT->stop();
67 }
68 }
69
70 void Dialog::sltTimerNoT()
71 {
72 m_systemTray->setIcon(QIcon(":/image/qicon_no.png"));
73 timerT->start(300);
74 if(timerNoT->isActive())
75 {
76 timerNoT->stop();
77 }
78 }
