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

UIObject class

Inheritance MovieClip > UIObject
ActionScript Class Name
UIObject is the base class for all version 2 components; it is not a visual component. The
UIObject class wraps the ActionScript MovieClip object and contains functions and properties
that allow version 2 components to share some common behavior. Wrapping the MovieClip class
allows Macromedia to add new events and extend functionality in the future without breaking
content. Wrapping the MovieClip class also allows users who aren't familiar with the traditional
Flash concepts of "movie" and "frame" to use properties, methods, and events to create
component-based applications without learning those concepts.
The UIObject class implements the following:
•
Styles
•
Events
•
Resize by scaling
To use the methods and properties of the UIObject class, you call them directly from whichever
component you are using. For example, to call the
RadioButton component, you would write the following code:
myRadioButton.setSize(30, 30);
You only need to create an instance of UIObject if you are using version 2 of the Macromedia
Component Architecture to create a new component. Even in that case, UIObject is often created
implicitly by other subclasses like Button. If you do need to create an instance of UIObject, use
the following code:
class MyComponent extends UIObject;
