Hi Mikael I assume you use spec with the Morphic underlying graphical library.
In your presenter: - `anEvent position` will give you the event position in the global world coordinate. - `self adapter widget position.` will give you the top left corner underlying Morph position in the global world coordinate. `anEvent position - self adapter widget position` should give you the position you're looking for.
