Qt implements system pallets and qt implements pallets

Most of the software we see usually comes with a system tray, so that the software can run in the background, which is quite good. Today, I checked the demon that comes with Qt. I have a reference in the middle. After implementing this small function, I added this function to my previous project. The effect is quite good. The interface is as follows:

Right-click the system tray to display the menu functions currently set:

How about it? The effect is fine. We are satisfied with the implementation of this small function hall. You can right-click the pop-up menu to set what you need. In addition, you can set the actions triggered when you click, double-click, and press the intermediate key respectively. The main code is as follows:

1. First, add the header file, including the Qsystem/trayIcon class, QMenu class, And QAction class.

<Span style = "font-size: 18px;"> <strong> QSystemTrayIcon * myTrayIcon; // System Tray pointer QMenu * myMenu; // System Tray menu QAction * miniSizeAction; // minimize QAction * maxSizeAction; // maximize QAction * restoreWinAction; // restore QAction * quitAction; // exit QAction * checkUpdate; // check for updates </strong> </span>

Function implementation:

<Span style = "font-size: 18px;"> <strong>/** function: Create a system tray menu * input parameter: none * output parameter: none * description: this function is used to create a system tray menu. Users can click the corresponding menu to perform operations */void MainWindow: CreateTrayMenu () {miniSizeAction = new QAction (tr ("minimal (& N) "), this); miniSizeAction-> setToolTip (tr (" minimal "); miniSizeAction-> setIcon (QIcon (":/images/systemtrayico/minac.png ")); maxSizeAction = new QAction (tr ("maximize (& X)"), this); maxSizeAction-> setToolTip (tr ("maximize"); maxSizeAction-> SetIcon (QIcon (":/images/systemtrayico/maxac.png"); restoreWinAction = new QAction (tr ("Restore (& R)"), this ); restoreWinAction-> setToolTip (tr ("Restore"); restoreWinAction-> setIcon (QIcon (":/images/systemtrayico/restoreac.png ")); quitAction = new QAction (tr ("Quit (& Q)"), this); quitAction-> setToolTip (tr ("quit ")); quitAction-> setIcon (QIcon (":/images/systemtrayico/exitac.png"); checkUpdate = new QAction (tr ("check for updates (& C) "), This); checkUpdate-> setToolTip (tr (" check for updates "); checkUpdate-> setIcon (QIcon (":/images/systemtrayico/updateac.png ")); // connect the menus to the SLOT and trigger the corresponding action connect (miniSizeAction, SIGNAL (triggered (), this, SLOT (hide (); connect (maxSizeAction, SIGNAL (triggered (), this, SLOT (showMaximized (); connect (restoreWinAction, SIGNAL (triggered (), this, SLOT (showNormal ())); connect (quitAction, SIGNAL (triggered (), this, SLOT (logoutWidg Et (); connect (checkUpdate, SIGNAL (triggered (), this, SLOT (checkSysUpdate ())); // Add the created menu object to the menu of the system tray. myMenu = new QMenu (QWidget *) QApplication: desktop (); myMenu-> addAction (miniSizeAction ); myMenu-> addAction (maxSizeAction); myMenu-> addAction (restoreWinAction); myMenu-> addSeparator (); myMenu-> addAction (checkUpdate); myMenu-> addSeparator (); // Add a separator myMenu-> addAction (quitAction);}/** function: System icons and display of some information * Description: determines whether the system supports system graphic disk icon special effects. You can execute corresponding actions */void MainWindow: CreateTrayIcon () {CreateTrayMenu (); // determines whether the system supports the system tray icon if (! QSystemTrayIcon: isSystemTrayAvailable () {return;} myTrayIcon = new QSystemTrayIcon (this); myTrayIcon-> setIcon (QIcon (":/images/main.png ")); myTrayIcon-> setToolTip (tr ("Volkswagen supermarket cash register system V2.0"); myTrayIcon-> showMessage ("Volkswagen software", "the software enters the minimization mode, click "Restore", QSystemTrayIcon: Information, 10000); myTrayIcon-> setContextMenu (myMenu); myTrayIcon-> show (); connect (myTrayIcon, SIGNAL (activated (QSystemTrayIcon :: activationReason), this, SLOT (iconAcitvated (QSystemTrayIcon: ActivationReason); }</strong> </span>

Click Event processing:

<Span style = "font-size: 18px;"> <strong>/** function: Click the corresponding action on the system tray menu. * description: when you click the action * (left and right) triggered by clicking the menu, click, double-click, and intermediate button. You can process the corresponding events */void MainWindow: iconAcitvated (QSystemTrayIcon: ActivationReason reason) {switch (reason) {case QSystemTrayIcon: Trigger: this-> showNormal (); break; case QSystemTrayIcon: DoubleClick: this-> showMaximized (); break; case QSystemTrayIcon: MiddleClick: // break; default: break ;}} </strong> </span>

This is the basic code.
