Using ESP8266WebServer from within a class definition
Posted: Sun May 07, 2017 11:54 pmI'm working on a project and my code was starting to get unmanageable in a single structured INO so I started refactoring some of the task-specific code out into class definitions. I would like to set up one such class to handle a WebServer for changing configuration parameters. The first thing I ran into was that I need to do my 'handleClient' somewhere in my main program loop so I made a method that triggers it within the class. But now I have a problem compiling the class in that the set-up code isn't working right when I'm trying to point the server config to run a class method.
relevant code from my my class header file CfgServer.h:
relevant code from the cpp file CfgServer.cpp:
My cut/paste is not currently working from my vnc window to the machine running the Arduino ID, but the error I am getting back is 'no matching function call to 'ESP8266WebServer::onNotFound()'
I'm assuming this is because it's pointing at the internal class method and I'm doing it wrong. Is there a way to get this to work? Or am I going about it the wrong way?

/*
