Hi, I found some posts about this topic, but they did not clarify things in my head well enough, so I have to start my own... :)
I'm basically craving for multiple inheritance or mixins, at least with my current way of thinking. I haven't really gone deep enough with multimethods or protocols, so I might be a little off track by looking for multiple inheritance. Let's take an example: I want to implement some gui widgets, so there's a main method "render" which draws the widget on the screen. I want to have two types: - Textfield - Datetimepicker Each can be "mixed" with the Label widget, so that we have: - LabelledTextfield - LabelledDatetimepicker So, two challenges occur: 1/ the render method for Label needs to call the render method for it's "mixed" widget (either Textfield or Datetimepicker) - let's assume that labels are rendered "around" the actual widget, so that we have a simple way to mix the implementations of render method 2/ the Label widget comes with its own data (the label text) For the second thing, I think it will work with defrecords, since the label can be a map entry which can be stored in the actual widget, even if it's not mixed with Label. I still want to point this out in case there are other ways of achieving this. How can I achieve 1? Are there alternatives for 2?
