Syntax

class UGizmoViewContext : public UObject

Remarks

A context object that is meant to hold the scene information for the hovered viewport on a game thread, to be used by a gizmo later for hit testing. The organization mirrors FSceneView so that functions could be written in a templated way to use either FSceneView or UGizmoViewContext, though UGizmoViewContext only keeps the needed data.
