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 can���t 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, it���s just that I can���t seem to find it.
Kind regards,
Mikael
