Detailed Description

Class EventHandler This class will be your command center...

All messages and windows content are created here You will have to create a class that inherits from EventHandler. You have to implement the two followings methods:
void messageTreatment(Element* src,UINT msg);
void initApplication();

Your constructor should have a HINSTANCE parameter.

So, you will have something like that:

 class MyApp:
 public EventHandler
 {
 protected:
 //function to init application (add item to our window, init var, etc.)
 void initApplication();
 public:
 MyApp(HINSTANCE hInstance);
 ~MyApp(void);
 //function which is called when events appends
 void messageTreatment(Element* src,UINT msg);
 };
