Will do that.

I was thinking of making a custom component in C++ and exposing that one as
a QML component. For example "ToolTipPrivateData" which just holds all the
data and emits signals when something is changing. Right now that's not
really required but would make it nicer :) Not quite sure yet if i'm going
to do that.

Ehh, how do i use that one? I can't give a position with that function (it
returns a position).

It certainly has something.. I will recheck and come back to you about this
one.
