    Hi,

    Yes. Change opacity of the Rectangle and "setColor":http://doc.qt.io/qt-5/qquickwindow.html#color-prop of QQuickView to transparent.

      does it depend on version? I mean I have Qt 2.4 max and can't see anything like that or do I need to import something?

          Sure, here you go:

          main.cpp
          @
          QQuickView view;
          view.setColor(Qt::transparent);
          view.setSource(QUrl(QStringLiteral("qrc:///main.qml")));
          view.show();
          @

          main.qml
          @
          import QtQuick 2.4

          Rectangle {
          width: 300
          height: 300
          color: "red"
          opacity: 0.1
          }
          @

          Hope this is what you meant..

              It seems you are using qmlscene to load the QML file, then you need to pass "--transparent" argument to it.

                  Are you using QtCreator to execute that file ?

                      Then Keeping your current project selected, go to
                      QtCreator > Projects (On Left side pane) > Build & Run > Run > Run > Arguments

                      and add "--transparent" as argument there for qmlscene.

                      Note: There are two hypens for transparent, it appears to be combined after posting.

                                Yes exactly. Just remove the double quotes.

                                    So what doesn't work for you ? If you have a Text element in this QML it will displayed as it is. It wont be affected by transparency.

                                        It seems the Window itself has completely disappeared. Since I can't see it running in the task bar.

                                        Here is what it looks like on my machine:
                                        !http://i.imgur.com/8gLea96.jpg(Image3)!

                                        Kept the default Project template like yours and just added color and opacity for rectangle. In my case it is seen running in taskbar.
