All virtual classes.

The virtual.Widget consists of five parts, which are Shape, Text, Image, Style and Feature. In addition, they can be nested within each other.

Where Feature is the function of widgets, Style control the color of the widget, and each widget can be bound to up to one Feature and one Style, but in terms of appearance, there is no limit to the number of Shape, Text, and Image.

Shape, Text, and Image are all appearance elements that inherit from abstract base class Elements.
