Qt QGraphicsTextItem Set Item To Stick To Dragged Position

I'm trying position a text and I want it to stick to where ever the user has dragged it for example bottom right it will stay there and when the view gets resized the text item stays bottom right, so it dynamically changes position with the view.

I've tried to SetPos but I think due to the maths I'm having a hard time to figure out how to set the correct POS for the text as the view is resizing. I've created a simpler version of the code I have that allows text dragging, if anyone has solved this in their project I would love to hear how, thanks.
