Implementing Form Controls

With the help of form controls, the users are enabled to implement data and work with data to provide them interaction capability with the application. Every Form UI control inherits properties from UIComponent class which in turn inherits properties from EventDispatcher and other top level classes.

Flex EventDispatcher Class

The EventDispatcher class is the base class for all classes that can dispatch events. The EventDispatcher class allows any object on the display list to be an event target and as such, to use the methods of the IEventDispatcher interface.

Flex UIComponent

The UIComponent class is the base class for all visual components, both interactive and non-interactive.
