Transfering Events from Classes used as Property inside a Major Collecting Class
f#classes

Dear All,

I would like to "trasfer" the "Property Changed Event" from classes used as properties inside a "major" class (see the example below).

Is this a "Good/Best Style" to perform this pourpose?

Let me know if there is an other most "intelligent" way!

Many thanks in advance!

SCOPE: Create an auto-updating windows form.

Hi,

the code looks reasonable to me. Using the "Add" method is correct.

I don't know of a better way to propagate an event automatically from a nested class, but would also be interested in one.

I'm use to install and remove event handler and therfore I really do not know if the simply method ADD defined inside a class remove the event habdler once the class in which it is defined shall be "destroyed"/"disposed".

Have you an idea how to test the above described scenario?

Thanks

I believe an instance of MainClass will not be garbage-collected as long as its members are accessible through the event handler function. In other words, instances of MainClass will live at least as long as the instance of NestedClass that they are attached to.

When both a MainClass instance and the associated NestedClass instance become unreachable, both should eventually get garbage-collected.

At least that is what I would expect from a reasonable implementation.

See here for some ideas how to test these things:
