Hi,
I guess that properly you should do:
(self globalPointToLocal: event position) - self position
which should deal with the case of being embedded in a scroll pane or other
transform

Subject: Re: [Pharo-project] Mouse handler on a morph
Okay, but i didn't find anything with globalToLocal. And i've find another
solution, just use soustraction for this problem :
captureMouse: event
Transcript cr;show: event position - self position.
That's work too :)
Thanks ;)

This is because, under rare circumstances, it is desirable to do
something in/on/to the desktop based on the position in the local
morph.
To get the local coordinates look for a method with the word "global"
in it -- globalToLocal: or something like that. It's in Squeak, not
sure whether this is still in Pharo though.. If anything, you could
always just subtract the upperleft coordinate of your window from the
MouseEvent's position..
