    \class Macro::IEventHandler
    \brief The IEventHandler class is a base class for all macro event handlers.

    An event handler is used to handle a specific type of macro events.
    They are used to create and replay macro events, use MacroManager::registerEventHandler
    to add a new event handler.
*/

/*!
    \fn void IEventHandler::startRecording(Macro* macro)

    This method is called when starting to record a macro, it can be used
    to initialize some data.
*/

/*!
    \fn void IEventHandler::endRecordingMacro(Macro* macro)

    This method is called after recording a macro, to cleanup everything.
*/

/*!
    \fn bool IEventHandler::canExecuteEvent(const MacroEvent &macroEvent)

    When replaying a macro, the manager iterate through all macro events
    in the macro and call this method to know which handler to use.
    If the method returns true, executeEvent is called.
*/

/*!
    \fn bool IEventHandler::executeEvent(const MacroEvent &macroEvent)

    This method execute a specific macro event, using the values stored in
    the macro event.
