Syntax
class UClickDragTool :
public UInteractiveTool,
public IClickDragBehaviorTarget
Remarks
UClickDragTool is a base tool that basically just implements IClickDragBehaviorTarget, and on setup registers a UClickDragInputBehavior. You can subclass this Tool to implement basic click-drag type Tools. If you want to do more advanced things, like handle modifier buttons/keys, you will need to implement IClickDragBehaviorTarget yourself
