Uicomponent Class - MACROMEDIA FLASH MX 2004-USING COMPONENTS Use Manual

UIComponent class

The UIComponent class does not represent a visual component; it contains methods, properties,
and events that allow Macromedia components to share some common behavior. All version 2
components extend UIComponent. The UIComponent class lets you do the following:
•
Receive focus and keyboard input
•
Enable and disable components
•
Resize by layout
To use the methods and properties of UIComponent, you call them directly from whichever
component you are using. For example, to call
component, you would write the following code:
myRadioButton.setFocus();
You only need to create an instance of UIComponent if you are using version 2 of the
Macromedia Component Architecture to create a new component. Even in that case,
UIComponent is often created implicitly by other subclasses such as Button. If you do need to
create an instance of UIComponent, use the following code:
class MyComponent extends mx.core.UIComponent;
