Dear Qt Specialists!

I would like to access, lets say every 10 millisecond, a certain QT-QML variable (I am not even sure if I am speaking the proper wording) from C++ and use that information to run some code in C++ to manipulate some external, not connect through the QML, platform.

For example: imagine, QML provides a particular value from a certain sensor, which is continuously updating. I would like to periodically access this from C++ to move the mouse cursor in linux.

Any suggestions? Thank you all.
