Overrides:

build in class Gesture.Builder<B extends GestureZoom.Builder<B>>

Returns:

a new instance of GestureZoom with the properties that were set in the Builder object.

onScaleChanged

public B onScaleChanged(GestureZoom.ScaleChangedCallback handler)

Emitted whenever the distance between both tracked sequences changes.

Parameters:

handler - the signal handler
