I'm using NetConnection in several places in my application. I'd like to create a class to extend NetConnection that would open a popup window to display feedback to tell the user to wait while communicating with the server. The idea is to put this in the extended NetConnection class so that I don't have to repeat the feedback code every time I contact the remote server in the code.
I had thought I'd be able to extend the "call" function to open the feedback window and detect completion of the data transfer to close it. Unfortunately it looks like the call function is not marked extendable. Has anyone else tried to do this? Any ideas of where I should be looking, or examples? Thanks.
