What changed?
The new
IDragInfoBuilderandIDropInfoBuilderare great, but there are still some scenarios where it's not possible to override default behavior.This PR further embraces the
IDragInfoandIDropInfointerfaces, enabling more custom implementations.I needed this when implementing drag-n-drop for a custom multi selection tree view.
Breaking changes
IDragInfoBuilder.CreateDragInfonow returnsIDragInfoinstead ofDragInfoIDropInfoBuilder.CreateDropInfonow takes anIDragInfoinstead ofDragInfoRefreshSourceItemsmethod added toIDragInfo. This is not really a breaking change, as up until this PR, it wasn't possible to use a fully custom implementation ofIDragInfoand any existing implementations will be inheriting fromDragInfo.
