(

typename MessageMapType::itsBoolFunctionTakingInt

eventHandler

)

Setting the event handler for the "char" event.

If supplied event handler is called when control has the focus and character event occurs
parameter passed is int which is the character of the nonsystem key being pressed. Return value must be of type bool, if event handler returns true event is defined as "handled" meaning the system will not try itself to handle the event.
