[Pharo-project] problem with updating checkBoxes in morph
Hi, Here is what I want to do: - I have checkbox: ChekboxMorph new - A checkbox is made of a label and a button - I want to do a specific action when there is a mouse click on the button For that: - I saw that there is a method #on:send:to: in Morph with wich we can do: checkbox on: #click send: #amessage to: receiver Problem: - when I do checkbox on: #click send: #amessage to: receiver, all is ok. - when I do checkbox buttonMorph on: #click send: #amessage to: receiver, to consider the click on the button, it doesn't work, the event is never handled (whereas #mouseDown for example is handled).
cyrille do you have a piece of code to illustrate your problem? Let me rephrase our discussions: you can get the associated checkbox event (set by on: #click send: #amessage to: receiver) raised only when you click on the label but not on the tick. And that checkbox buttonMorph on: #click send: #amessage to: receiver, is not working on click but checkbox buttonMorph on: #mouseDown send: #amessage to: receiver, is.

I'm a bit wonder, why you sending a #buttonMorph to checkbox morph, trying to intercept a messages? As to me this is a wrong approach, because you as a user of checkbox, should not care about its internals, and speak directly with checkbox public layer , but not with its internal components. 2009/10/6 Cyrille Delaunay <cy.delaunay@gmail.com>:
