[SOLVED]QSystemTrayIcon for console applications



  • Hi all,

    Can I use QSystemTrayIcon for console applications?

    PS
    I tried to test it by using the following snippet but I got a runtime error:

    ---main.cpp

    @
    #include <QtCore/QCoreApplication>
    #include <QSystemTrayIcon>

    int main(int argc, char *argv[])
    {
    QCoreApplication a(argc, argv);

    QSystemTrayIcon *iconTray = new QSystemTrayIcon(QIcon(":/pixmap/res/icon.png"));
    iconTray->show();
    
    return a.exec(&#41;;
    

    }
    @

    ---test.pro

    @
    QT += core

    QT += gui

    TARGET = TRAY-APP
    CONFIG += console
    CONFIG += app_bundle

    TEMPLATE = app

    SOURCES += main.cpp

    RESOURCES +=
    res.qrc
    @

    ---runtime error
    @
    QWidget: Cannot create a QWidget when no GUI is being used

    This application has requested the Runtime to terminate it in an unusual way.
    Please contact the application's support team for more information.

  • You can build a console application in the sense that there is no main window or GUI or the like. But as you instantiate a GUI element - the QSystemTrayIcon - your application needs to initialize the graphics system. Therefore your need a QApplication instead of a QCoreApplication. If you change that, the code should work.



  • Thanks a lot... it's working fine
