Inserting Delegate Stubs in VS2012 (CS)

Introduction

In Visual Studio 2012, you can automatically insert delegate stubs based on their signature in C#.

Example

Consider the simple example below:

1. class SubscribeToDelegates

2. {

3.     rxCustomUI _customUI;

5.     public SubscribeToDelegates()

6.     {

7.         // Create a new customUI obj

8.         _customUI = rxCustomUI.create("my_test_ctx");

10.         // Create a new button

11.         rxButton myButton = new rxButton();

13.         // Create a new delegate of the correct signature

14.         // NOTE1: We use class rxButtonDelegates to conveniently get the desired delegate type

15.         // NOTE2: The delegate stub hasn't been provided at this point

16.         var myDel = new rxButtonDelegates.onAction(MyOnAction);

18.         // Subscribe to the button's onAction delegate

19.         myButton.onAction = _customUI.make_delegate(myDel);

21.     }

22. }

• Note1: At this point we haven't yet provided the delegate stub, so intellisense marks myOnAction with red squiggles:

  

• Note2: When clicking inside MyOnAction, intellisense provides us with the option to insert the delegate stub automatically:

  

The class now becomes:

1. class SubscribeToDelegates

2. {

3.     rxCustomUI _customUI;

5.     public SubscribeToDelegates()

6.     {

7.         // Create a new customUI obj

8.         _customUI = rxCustomUI.create("my_test_ctx");

10.         // Create a new button

11.         rxButton myButton = new rxButton();

13.         // Create a new delegate of the correct signature

14.         // NOTE1: We use class rxButtonDelegates to conveniently get the desired delegate type

15.         // NOTE2: The delegate stub hasn't been provided at this point

16.         var myDel = new rxButtonDelegates.onAction(MyOnAction);

18.         // Subscribe to the button's onAction delegate

19.         myButton.onAction = _customUI.make_delegate(myDel);

21.     }

23.     private void MyOnAction(IRibbonControl control)

24.     {

25.         throw new NotImplementedException();

26.     }

27. }
