Pie Menu Simple Example

  • Hi,

    can someone please help me fix this error message:

    Starte C:\Users\Rick\Documents\build-Custom-Desktop_Qt_5_10_0_MSVC2017_64bit-Debug\debug\Custom.exe...

        PieMenu {
            id: pieMenu
            MenuItem {
                text: "Action 1"
                onTriggered: print("Action 1")
            MenuItem {
                text: "Action 2"
                onTriggered: print("Action 2")

    Examle from:

    int main(int argc, char *argv[])
        QGuiApplication app(argc, argv);
        QQmlApplicationEngine engine;
        if (engine.rootObjects().isEmpty())
            return -1;
        return app.exec();

    After 2 hours I still couldn't fix it although it is a simple example.

    System: Windows 10 x64, MSVC2017, Qt 5.10.0

    Thank you all and sorry for this beginner question.



    PS: I also tried QML lists ([MenuItem{...}, MenuItem{...}]) and repeaters. Same error message.

  • The problem is that MenuItem is member of QtQuick.Controls 1.* module and you are importing QtQuick.control 2.2.

    The below code solve your problem:

    import QtQuick 2.9
    //import QtQuick.Controls 2.2
    import QtQuick.Controls 1.4
    import QtQuick.Window 2.2
    import QtQuick.Extras 1.4
