qt - how the QtObject element works in QML

Question

I just want to know what this QtObject elements does, its seems that is reactive, because in the tutorial that I followed, use it for update the color of a button, so, I want to know how I can use it, and how its works, and how I can use in other cases.

while your are working on QML file need to hide some properties from upper layer Item ( some thing's like private variable and methods). best case for get a right way for incapsulation in QML is to using a internal item like QtObject . in your code used a QtObject for block the external direct access to button color and bind the color to the button item state.
