HtWidget
========

[](#htwidget)

Overview
--------

[](#overview)

This class can be used to define different types of widgets. But what is a widget? A widget is an interactive field/element which has some sort of state and allows users to communicate with a server or a backend. Notice that not all form fields are interactive. A [hidden field](https://github.com/flsouto/hthidden), for instance, even though it has a state, it does not provide any form of direct interaction. A [button](https://github.com/flsouto/htbutton) is also not a widget, in my opinion, because it doesn't allow any complex interaction other than just clicking on it. An input text field or a checkbox, on the other hand, can be considered to be a widget because they do have a state and require some kind of interaction. In this documentation we are going to see how to implement a simple TextField class which inherits from HtWidget.

**Notice:** A lot of functionality is inherited from a more basic abstract class called HtField. If you find difficulties in understanding some of the features being reused here, please refer to [this documentation](https://github.com/flsouto/hthidden).
