Qt實現個性化系統托盤
今天剛好有點時間,就想着模仿下電腦管家的系統化托盤,看着挺好看的。下邊是電腦管家自帶的系統托盤:
可以看出主要是由三部分組成的,分爲上部,中間和底部,上邊是
2個label,加2個圖標label;中間是6個按鈕,文字顯示在底部,只能是QToolButton了,QPushButton辦不到;底部也是2個圖標label加2個開關按鈕(開關按鈕需要自己實現狀態切換),最底部用3個QPushButton就可以了。
好了,有了上面的分析就可以開始進行設計了。
- 新建一個工程,名字就叫ComputerManager吧,類名和其他不變,Widget吧。本次將系統托盤的實現獨立出來,封裝成一個類。
新建一個C++類,作爲系統托盤的具體實現,叫ComputerManager,繼承自QSystemTrayIcon,源碼中有詳細介紹。

}
4 初始化中間菜單和Action
void ComputerManager::initMidAction()
{
m_midWidget = new QWidget();
m_midWidgetAction = new QWidgetAction(m_trayMenu);
m_speedLabel = new QLabel(tr("Auto backup"));
m_SpeedBtn = new mySwitchButton();
m_SpeedBtn->setFixedSize(60,25);
m_SpeedBtn->setObjectName(QString("TrayButtonAuto"));
m_SpeedBtn->SetCheck(true);
QHBoxLayout *m_midUpLayout = new QHBoxLayout();
m_midUpLayout->addWidget(m_speedLabel);
m_midUpLayout->addWidget(m_SpeedBtn);
m_troubleLabel = new QLabel(tr("Auto Start"));
m_troubleLabel->setToolTip(tr("computer now "));
m_TroubleBtn = new mySwitchButton();
m_TroubleBtn->setFixedSize(60,25);
m_TroubleBtn->setObjectName(QString("TrayButtonAuto"));
m_TroubleBtn->SetCheck(true);
QHBoxLayout *m_midBottomLayout = new QHBoxLayout();
m_midBottomLayout->addWidget(m_troubleLabel);
m_midBottomLayout->addWidget(m_TroubleBtn);
QVBoxLayout *m_midMainLayout = new QVBoxLayout();
m_midMainLayout->addLayout(m_midUpLayout);
m_midMainLayout->addLayout(m_midBottomLayout);
m_midWidget->setLayout(m_midMainLayout);
m_midWidgetAction->setDefaultWidget(m_midWidget);
}
5 初始化底部菜單和Action
void ComputerManager::initBottomAction()
{
m_bottomWidget = new QWidget();
m_bottomWidgetAction = new QWidgetAction(m_trayMenu);
m_ReportBtn = new QPushButton(QIcon(":/image/mainMenu/update.png"), tr("Update"));
m_ReportBtn->setObjectName(QString("TrayButton"));
m_ReportBtn->setFixedSize(60, 25);
m_InformBtn = new QPushButton(QIcon(":/image/mainMenu/about.png"), tr("About"));
m_InformBtn->setObjectName(QString("TrayButton"));
m_InformBtn->setFixedSize(60, 25);
m_exitBtn = new QPushButton(QIcon(":/image/mainMenu/quit.png"), tr("Exit"));
m_exitBtn->setObjectName(QString("TrayButton"));
m_exitBtn->setFixedSize(60, 25);
QHBoxLayout* m_bottomLayout = new QHBoxLayout();
m_bottomLayout->addWidget(m_ReportBtn, 0, Qt::AlignCenter);
m_bottomLayout->addWidget(m_InformBtn, 0, Qt::AlignCenter);
m_bottomLayout->addWidget(m_exitBtn, 0, Qt::AlignCenter);
m_bottomLayout->setSpacing(5);
m_bottomLayout->setContentsMargins(5,5,5,5);
m_bottomWidget->setLayout(m_bottomLayout);
m_bottomWidgetAction->setDefaultWidget(m_bottomWidget);
}
6 **將所創建的Action添加到QMenu中**
void ComputerManager::initAction()
{
this->setToolTip(tr("Computer Manager"));
this->setIcon(QIcon(":/image/system_tray.png"));
m_trayMenu = new QMenu();
this->setContextMenu(m_trayMenu);
}
7 **外部調用**
m_systemTray = new ComputerManager(this);
“`
m_systemTray->show();
Qt利用語言家實現多語言翻譯
軟件開發中可以使用Qt強大的語言家進行翻譯,保證不會出現大家所謂的亂碼問題。
完成後的樣子如下圖所示:
