Syntax
UCLASS (MinimalAPI)
class ULocalClickDragInputBehavior :
public UClickDragInputBehavior ,
public IClickDragBehaviorTarget
Remarks
ULocalClickDragInputBehavior is an implementation of UClickDragInputBehavior that also implements IClickDragBehaviorTarget directly, via a set of local lambda functions. To use/customize this class the client replaces the lambda functions with their own. This avoids having to create a second IClickDragBehaviorTarget implementation for trivial use-cases.
