The widget is the base class for all qooxdoo widgets. It contains the core functionality of the whole widget system.

A widget consists of at least three HTML elements. The container element, which is added to the parent widget has two child Element: The "decoration" and the "content" element. The decoration element has a lower z-Index and contains markup to render the widget's background and border using an implementation of qx.ui.decoration.IDecorator.The content element is positioned inside the "container" element to respect paddings and contains the "real" widget element.

There are no explicit widget demos since the widget is typically sub classed.
