[Cuis-dev] New Feature! - MultiSelect

[Juan Vuletich]

Hi Folks,

I've finally spent a couple of hours reviewing this. I like the idea, 
and it seems to work. Some comments:

- #buildMorphicSingleMessageList uses a PluggableListMorphOfMany and is 
essentially the same as #buildMorphicMultipleMessageList.
- #buildMorphicMultipleMessageList has no senders at all
- It looks like the intention was to allow the user to choose between a 
single-selection and a  multi-selection method list, but no such 
preference is provided
- #turnMouseButton1Into2 is deactivated, but some people may be using it 
with a single-button mouse. I agree that this clashes with the common 
gestures for multiple selection, but removing this needs consensus in 
the community, or an alternative that keeps support for 1-button mice 
working.
- #OnShiftPressedSelectFrom:To: has both keywords starting in uppercase. 
This is not common Smalltalk style.
- The current behavior of PluggableListMorphOfMany is to allow using 
click to select and to deselect elements. This is useful, for instance 
in the MethodSetWindow hierarchy. Is disabling this needed?

I think this code needs some more work, and some consensus on the 
changes that affect existing behavior.

Thanks,
