I am new to C++, so please take me easy. I want to make a low-level game engine only using C++, OpenGL and GLFW. This is a continuation of Event System using C++ ; I added the suggestions. Here's a diagram of the improved event system:

I know I could implement a FSM for the InputManager, but for the moment, i do not need it -instead of the bool textInputMode. I would appreciate very much some feedback.

Here's the source code for the event system:

Event.h

KeyboardEvent.h

MouseEvent.h

WindowEvent.h

EventQueue.h

EventListenerID.h

EventListener

EventListenerRegister.h

EventBus.h

EventManager.h

Here's the InputManager:

MouseState.h

KeyboardState.h

CharState.h

InputManager.h

InputManager.h
