QML and DBus in plasma

[Rohan Garg]

Hi Weng
I've been looking into a solution for this myself as well, and the best way
i could come up was using C++/Python and then using the setContextProperty
to set the property of any QML objects, the code would be something like
this [1][2].
I found these Qt docs [3] to be quite helpful in this case. But yes, i would
absolutely love it if there was a way to access DBus interfaces from within
QML.
