Qt module not installed in QtDesigner

Diracsbracket

@mr.jo
Yes, I agree. These false warnings are annoying and should get fixed.

mr.jo

@Diracsbracket but if u check in QT instalation folder in /qt/version/gcc_64/ there is all module that u installed, maybe qtcreator not using that path so qtcreator got that warning. if u check in /qt/Tools/QtCreator/lib/Qt/qml ,that folder not contain all module maybe just base module.

I have all modules, yet get the warnings, even in Qt Creator after a while in the QML source code. That must be a bug.

mr.jo

@Diracsbracket i tried to compile plugin qtchart again from source and get libqtchartdesigner.so then i put in path gcc_64/plugins/designer, after that i run designer from gcc_64/bin/ (standalone), and i got qt chart chartview widget, but still not have qtchart widget in qt quick designer(qt creator). :D im still tried how this application works perfectly haha. maybe because configuration path in qml emulation layer, but i dont know what it is :D

@mr.jo
To be honest, I've never used Designer for QML. Due to the declarative nature of QML, I find it easier to just work from the code directly.

mr.jo

@Diracsbracket me too bro, but im curious with that warning, im using designer just want to know how my app looks like, without waiting for compilation. :D because the more complex the application is the longer the compilation.

@mr.jo
Sure.

mr.jo

@Diracsbracket thank bro for your infomation. :D

int main(int argc, char *argv[])
{
    // Qt Charts uses Qt Graphics View Framework for drawing, therefore QApplication must be used.
    QApplication app(argc, argv);

    QQuickView viewer;

    // The following are needed to make examples run without having to install the module
    // in desktop environments.
#ifdef Q_OS_WIN
    QString extraImportPath(QStringLiteral("%1/../../../../%2"));
#else
    QString extraImportPath(QStringLiteral("%1/../../../%2"));
#endif
    viewer.engine()->addImportPath(extraImportPath.arg(QGuiApplication::applicationDirPath(),
                                      QString::fromLatin1("qml")));
    //***** [Solve] FORCE THE MODULE TO BE IMPORTED.
    QObject::connect(viewer.engine(), &QQmlEngine::quit, &viewer, &QWindow::close);
    
    qDebug() << viewer.engine()->importPathList();

    viewer.setTitle(QStringLiteral("QML Axes"));
    viewer.setSource(QUrl("qrc:/qml/qmlaxes/main.qml"));
    viewer.setResizeMode(QQuickView::SizeRootObjectToView);
    viewer.show();

    return app.exec();
}

[Output through qDebug()]
("/home/snjee/workspace_qt/maxelecPrjs/build-maxCoffeeTdsMeterApp-Desktop_Qt_5_15_2_GCC_64bit-Debug", "qrc:/qt-project.org/imports", "/opt/Qt/5.15.2/gcc_64/qml")

You can find the answer in the built-in "QML Axes" example source.
