Idea:Add Class Event In GOOP

[jiaweipray]

One class has three parts. Property,method,event.Class event is delegate in C# class and it is function pointer in C++ class.But I can not find it in GOOP.I think it can be implemented in labview used VI Ref and by ref class(See my file) . The class event can decouple 2 class and used frequency in OO.So I think it should be supported in GOOP Class.

Hi,

I saw this post first now. All notifications was gone when NI updated the forum 😞

It's a bit like the observer pattern, does anybody else thing this would be useful?
I normally use interfaces (that OpenGDS supports), to solves notifications like this.
Any more thoughts about this feature?

Mikael,

I think this would be great if were implemented in GDS having it as one more of the design pattern options in there!

thanks

Here is just a simple way to implement Events.

But this quick solution only works for ByRef classes.
