Module `Wrappers.Gesture_zoom`

type t =
  [ `gesture_zoom | `gesture | `event_controller | `object_ ] Gobject.obj

val new_ : unit -> t

Create a new GestureZoom

val get_scale_delta : t -> float

Gets the scale delta.

If @gesture is active, this function returns the zooming difference since the gesture was recognized (hence the starting point is considered 1:1). If @gesture is not active, 1 is returned.

val on_scale_changed : 
  ?after:bool ->
  t ->
  callback:(scale:float -> unit) ->
  Gobject.Signal.handler_id
