A MouseArea is an invisible item that is typically used in conjunction with a visible item in order to provide mouse handling for that item. By effectively acting as a proxy, the logic for mouse handling can be contained within a MouseArea item. For basic key handling, see the Keys attached property. A click is defined as a press followed by a release, both inside the MouseArea (pressing, moving outside the MouseArea, and then moving back inside and releasing is also considered a click). The mouse parameter provides information about the click, including the x and y position of the release of the click, and whether the click was held.

Calling C++ methods from QML In order to feedback data from the user to the business logic, QML must be able to call C++ methods. The basic question is, how to calculate plus continuously update my_qml_item.x and my_qml_item.y. Are there any good examples of Qt/QML for panning or dragging a QML item?

The dynamically created QML object is not accessible through its ID. We need other mechanisms for communication with dynamic objects and these are signals and QML signal objects connect method. By communication we mean exchange of information between the caller (main QML file) and the callee (dynamically created QML file) and in both directions.
