Okay, went through listener registrations in all behaviors - and they are
indeed inconsistent:
- some listen to control properties like focused (f.i. Button, Combo): adding
strong, often inline listeners
- some listen to control path properties like selection/Model/Indices (f.i.
ListView, TreeView): adding weak (inline or field) wrappers
- cleanup for all guarantees to make those listeners removable (without
touching their type) and actually remove them in dispose
So I tend to follow that approach here as well, opinions?
