The IFocusManagerComponent interface defines the interface
that focusable components must implement in order to
receive focus from the FocusManager.
The base implementations of this interface are in the UIComponent class,
but UIComponent does not implement the full IFocusManagerComponent interface
since some UIComponents are not intended to receive focus.
Therefore, to make a UIComponent-derived component be a valid focusable
component, you simply add "implements IFocusManagerComponent" to the class
definition.

A flag that indicates whether the component can receive focus when selected.
<p>As an optimization, if a child component in your component
implements the IFocusManagerComponent interface, and you
never want it to receive focus,
you can set <code>focusEnabled</code>
to <code>false</code> before calling <code>addChild()</code>
on the child component.</p>
<p>This will cause the FocusManager to ignore this component
and not monitor it for changes to the <code>tabFocusEnabled</code>,
<code>hasFocusableChildren</code>, and <code>mouseFocusEnabled</code> properties.
This also means you cannot change this value after
<code>addChild()</code> and expect the FocusManager to notice.</p>
<p>Note: It does not mean that you cannot give this object focus
programmatically in your <code>setFocus()</code> method;
it just tells the FocusManager to ignore this IFocusManagerComponent
component in the Tab and mouse searches.</p>

A flag that indicates whether child objects can receive focus.
<p><b>Note: </b>This property is similar to the <code>tabChildren</code> property
used by Flash Player.
Use the <code>hasFocusableChildren</code> property with Flex applications.
Do not use the <code>tabChildren</code> property.</p>
<p>This property is usually <code>false</code> because most components
either receive focus themselves or delegate focus to a single
internal sub-component and appear as if the component has
received focus.
For example, a TextInput control contains a focusable
child RichEditableText control, but while the RichEditableText
sub-component actually receives focus, it appears as if the
TextInput has focus. TextInput sets <code>hasFocusableChildren</code>
to <code>false</code> because TextInput is considered the
component that has focus. Its internal structure is an
abstraction.</p>
<p>Usually only navigator components, such as TabNavigator and
Accordion, have this flag set to <code>true</code> because they
receive focus on Tab but focus goes to components in the child
containers on further Tabs.</p>
<p>The default value is <code>false</code>, except for the
spark.components.Scroller component.
For that component, the default value is <code>true</code>.</p>
