    what is the error, what isn't working exactly?

    Note that you can only load dbeug libraries in debug builds and the same respectivly for release.
    Also when place the DLL and the qmldir file in the Qt dir (e.g. C:\Qt\Qt5.7.0-msvc2015\5.7\msvc2015\qml\MyModule) it will be loaded by Qt automatically.



  • @raven-worx i'll tell you what i exactly want to do
    i have created QT quick2 extension plugin library project in this project i have to have one qml file that draws one simple circle
    i have to use the plugin i.e generated by extension plugin into other qt quick application to draw the circle
    How to achieve this task if you give me step by step guidelines it would be helpful.

    did you read the link i've already posted? This actually contains everything to know.
    As i already said, once the plugin is built copy it to your Qt's qml directory and it can be loaded by other applications.

    I wont post a step-by-step guide, when there is everything already in the docs. If you have a specific question ask it.



  • @raven-worx i'm able to load the plugin successfully but i'm facing problem in loading qml component in this link they have used Clock.qml and plugins.qml how should i access that Clock.qml file in my application through plugin if i simply used Clock as component it showing me an erorr.

    in this example the Clock.qml is located in the file system.

    Place your QML files in a qrc file and compile it into the plugin.
    Then in your qmldir file you can also specify a qrc:// url, to make it look like this:

    module MyModule
    plugin mymodule
    MyType 1.0 qrc:///path/to/MyType.qml
    

    or leave out the list of QML files in the qmldir file and register the types in the plugins registerTypes() method:

    void registerTypes(const char *uri)
     {
            Q_ASSERT(uri == QLatin1String("MyModule"));
            qmlRegisterType( QUrl::fromUserIntput("qrc:///path/to/MyType.qml"), uri, 1, 0, "MyType");
     }
    

    Then use import MyModule 1.0 to load your plugin.



  • @raven-worx Thank you it worked nw
