I¹m working on my RBScript-based controller code, and it¹s all going well
but I have one more challenge....
I¹ve created a generic ³Controller² class. The code for the controller is
in an RBscript. I want to be able to register a callback, which will call a
callback method on a controller class instance. I think this might be where
I should use delegates?
Historically, I¹ve always had to use global module methods for callbacks.
This has the downside that I don¹t know (from within the callback) which
controller object triggered the callback. Since my different controller
types may need to use the same callback template (e.g. two UInt32 params,
returning a UInt32), I won¹t even know which type of controller caused the
callback, let alone which instance of the controller, in order to pass the
callback event on to the controller for processing.
I¹m rather hoping that delegates give me a way to set up these callbacks
using class-instance methods as the callback target. But I can¹t work out
what the code would be to do this. Do I need to define a delegate in a
module? Do I need a property on the class to represent the callback method?
Where would the callback code go?
Any help much appreciated!
Dave.
