NETLINK SYMBOL
AddEventHandler
AddEventHandler[obj@event, func]
assigns the specified Mathematica function func to be called when the given event event fires.
Details
- To use AddEventHandler, you first need to load .NET/Link using Needs["NETLink`"].
- AddEventHandler can be used to wire up Mathematica callbacks for events in .NET user interfaces, such as a button click.
- The following options can be given:
-
SendDelegateArguments All which delegate arguments to send to the Mathematica event handler function CallsUnshare False whether or not your event handler function calls the advanced function 
- The function argument can be a string, a symbol naming a Mathematica function, or a pure function, and it will be called with whatever arguments the event sends.
- AddEventHandler returns a delegate object that can be passed to RemoveEventHandler to remove the callback function.
- Alternatively, use NETNewDelegate to manually create a delegate and pass that as the second argument instead of the function.
