OnPinchDelta Method

 function Leadtools.Controls.InteractiveService.onPinchDelta( 
   e 
)

Parameters

Parameter	Type	Description
e	InteractivePinchDeltaEventArgs	Event data

Raising an event invokes the event handler through a function. The OnPinchDelta method also allows derived classes to handle the event without attaching a function to the event. This is the preferred technique for handling the event in a derived class.
Note to Inheritors: When overriding OnPinchDelta in a derived class, be sure to call the base class's OnPinchDelta method so that registered delegates receive the event.
