Qt5 QML module is not installed

Question

I\'m confused about modules in Qt QML. I\'ve read all the docs, but it doesn\'t make clear some basic ideas.

I understand that i can put a bunch of QML files into a

Answer 1

In my case (I have all QML files in qrc resources) worked to add qmldir to resources also and call method addImportPath("qrc:/") of QQmlApplicationEngine.

My main.cpp looks like:

QQmlApplicationEngine engine;
engine.addImportPath("qrc:/");
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

Important parts of my .pro file looks like:

RESOURCES += qml.qrc \
    MyModule/mymodule.qrc

QML_IMPORT_PATH += $$PWD

My qmldir:

module MyModule

MyItem          2.0 MyItem20.qml
MyItem          2.1 MyItem21.qml

My qrc:

    
        MyItem20.qml
        MyItem21.qml
        qmldir
    

And finally my main.qml:

import QtQuick 2.5
import QtQuick.Window 2.2

import MyModule 2.0

Window {
    visible: true
    width: 640
    height: 480

    MyItem {
        anchors.fill: parent
    }
}

QtCreator is happy (not underlining components and imports) and module is loaded. Hope this helps.
