I did a little search and I found Morph >> globalPointToLocal: aPoint ^self point: aPoint from: nil may be
image eventHandler whenMouseDownDo: [ :event | self handleMouseDown: event image globaâ¦..
].

I have a presenter that is a subclass of SpPresenterWithModel and it contains, among other things, an ImagePresenter with an autoscaling image (a Form). I want to capture mouse clicks on the image and get the coordinate of the click relative to the upper left corner of the Form.
My #initializePresenter method looks like this: initializePresenter image := self newImage image: self emptyImage; autoScale: true. image eventHandler whenMouseDownDo: [ :event | self handleMouseDown: event].
This works, and the #handleMouseDown: method is run whenever the mouse is pressed on the ImagePresenter, but the MouseButtonEvent reports global coordinates and I canât find out how to convert these to coordinates relative to the Form that the ImagePresenter holds. I have googled and found answers to similar old questions, but nothing that seems to apply to Spec2.
There must be a very simple solution to this, itâs just that I canât seem to find it.
Kind regards, Mikael
