TDelegateInterface

A template parameter that specifies the interface of the delegate to call when an event occurs.

TCallback

A template parameter that specifies the type of an object that represents an object and its callback member function.

TCallbackObject

A template parameter that specifies the object whose member function is the method to call when an event occurs.

TArg1

A template parameter that specifies the type of the first callback method argument.

TArg2

A template parameter that specifies the type of the second callback method argument.

TArg3

A template parameter that specifies the type of the third callback method argument.

TArg4

A template parameter that specifies the type of the fourth callback method argument.

TArg5

A template parameter that specifies the type of the fifth callback method argument.

TArg6

A template parameter that specifies the type of the sixth callback method argument.

TArg7

A template parameter that specifies the type of the seventh callback method argument.

TArg8

A template parameter that specifies the type of the eigth callback method argument.

TArg9

A template parameter that specifies the type of the ninth callback method argument.

callback

An object that represents the callback object and its member function.

object

The object whose member function is called when an event occurs.

method

The member function to call when an event occurs.

An object whose member function is the specified callback method.

The base of a delegate object must be IUnknown, not IInspectable.
