    Tried again using a new project named Main3 as below, copying the image folder into the project folder.
    Here is the content of the files:
    main3.pro
    main.cpp
    images.qrc
    main.qml
    page1.qml
    Page1Form.ui.qml
    qtquickcontrols2.conf

    The program runs:
    Issues window shows nothing.
    Application Output shows this:
    Starting C:\Users\Abbasi\Documents\QML\Main3\Main3\build-Main3-Desktop_Qt_5_9_0_MinGW_32bit-Debug\debug\Main3.exe...
    QML debugging is enabled. Only use this in a safe environment.

    Compile Output shows:
    12:35:55: Elapsed time: 00:00.

    And General Messages shows nothing.

    The app shows nothing as the output.
    What is the problem? Why can't I run this example successfully?
    Why everything with Qt is that complicated and confusing?

    You are still having issues with the paths/syntax
    The path you use is invalid
    Should have the form
    qrc:/images/filename.png

    Use the right click menu to make sure its correct.

            I made a default QML projected
            added image folder in project folder and used
            Image {
            id: root
            source: "qrc:/images/test.png"
            }

            and it loaded image.

            So what ever goes wrong in your project, its minor.

              I made a default QML projected

              Is it different from the "Qt Quick Console 2 Application" project? You yourself told me to create such a project above.

              added image folder in project folder and used
              Image {
              id: root
              source: "qrc:/images/test.png"
              }

              and it loaded image.

              So what ever goes wrong in your project, its minor.

              Do you do the works just like me? And do your files contain the same thing as mine? And yours works well?!
              I tried the example using three projects, Main, Main2 and Main3. None gave me the expected result.

                No it is such project.
                then added image{...} to ApplicationWindow

                      No unfortunately! Didn't you take a look at the website I offered?
                      I fear how I go on reading that book if its next examples are that vague! :-(

                        Yep. seems like a good book.
                        If you read it all, i think it will give lots of insights.
                        When you then know the classes and overall architecture, it should be easier to google
                        for other examples if needed.

                          Honestly I'm reading the official Qt book (in chapter 5 now) and that book too. So I expect to encounter many problems (since I'm teaching myself the both books without any tutor). but since there are useful websites and very helpful forums (like here), I think I can cope with them, although with difficulties.
