/**
 * @brief This class is responsible in creating input text box and it's management,
 * 
 * It reads End User input from UI widget and has public member slots to intract with 
 * with edit requests by Edit button provided by class ChatLabel via editRequestHandler() slot as well as 
 * getText() slot which privides string value of inputed text It also notifies class  \ref serialize 
 * via signal Mainchatbox::editready about edit accomplishment, so serializer class can proceed saving new changes
 * This class as well informs main widget Widget::controller slot via signal Mainchatbox::textready()
 * so the controller method of main widget reponds with creating new instance of class ChatLabel.
 * Additionally this class also monitors whether Return key is pressed as the same way it monitors if addButton::addButtonClicked
 * to know when text input must be considered accomplished.
