EventHandler.md

 With *event handler* here we mean anything that can continuously read from an event queue and process the received events.

-### EventHanler
+## EventHandler
 The **EventHandler** class, in additions to EventHandlerBase, also extends the ActiveObejct interface.  
 In fact an EventHandler is a special ActiveObject that periodically checks a synchronized queue of events. When new events are present they can be removed from the queue and processed.

+### Methods
 EventHadler offers two main methods:
 - **virtual void postEvent(const Event& ev)**: overridden from EventHandlerBase, it enqueues the event passed as a parameters.
-- **virtual void handleEvent(const Event& ev)**: protected method that is periodically called in the active objects thread. In fact in the *run()* method, whenever an event is present in the queue, it gets removed and the *handleEvent* method is called. The *handleEvent* method has to be overridden and implemented by any class that extends EventHandler.

 ### Example
 This example shows how to define a very simple custom EventHandler.
 
-##### MyEventHandler.h
+#### MyEventHandler.h
 The first thing we need to do is to import the required modules and to define a set of events. For more details you can look at the [Events](Events) page.  
 Here we define three possible events: `EV_1`, `EV_2` and `EV_3`.

 In order to test that our class works we can create a MyEventHandler object and start it.  
 We can then post some events and see what the output is.

-##### Output

 Remember to add the `test-myeventhandler.cpp` to `sbs.conf` and to specify all the needed includes.  
 After you run the example you should see the following output:
