| TabBarAccImpl is the accessibility implementation class |
| for spark.components.TabBar. |
| <p>When a Spark TabBar is created, |
| its <code>accessibilityImplementation</code> property |
| is set to an instance of this class. |
| The Flash Player then uses this class to allow MSAA clients |
| such as screen readers to see and manipulate the TabBar. |
| See the mx.accessibility.AccImpl and |
| flash.accessibility.AccessibilityImplementation classes |
| for background information about accessibility implementation |
| classes and MSAA.</p> |
| <p> |
| <b>Children</b> |
| </p> |
| <p>The MSAA children of a TabBar are its tabs. |
| As described above, the accessibility of these tabs is managed |
| by the TabBar; their own <code>accessibilityImplementation</code> and |
| <code>accessibilityProperties</code> are ignored by the Flash Player.</p> |
| <p> |
| <b>Role</b> |
| </p> |
| <p>The MSAA Role of a TabBar is ROLE_SYSTEM_PAGETABLIST.</p> |
| <p>The Role of each tab is ROLE_SYSTEM_PAGETAB.</p> |
| <p> |
| <b>Name</b> |
| </p> |
| <p>The MSAA Name of a TabBar is, by default, an empty string. |
| When wrapped in a FormItem element, the Name is the FormItem's label. |
| To override this behavior, set the TabBar's |
| <code>accessibilityName</code> property.</p> |
| <p>The Name of each tab is determined by the TabBar's |
| <code>itemToLabel()</code> method.</p> |
| <p>When the Name of the TabBar or one of its tabs changes, |
| a TabBar dispatches the MSAA event EVENT_OBJECT_NAMECHANGE |
| with the proper childID for the tab or 0 for itself.</p> |
| <p> |
| <b>Description</b> |
| </p> |
| <p>The MSAA Description of a TabBar is, by default, an empty string, |
| but you can set the TabBar's <code>accessibilityDescription</code> |
| property.</p> |
| <p>The Description of each tab is the empty string.</p> |
| <p> |
| <b>State</b> |
| </p> |
| <p>The MSAA State of a TabBar is a combination of: |
| <ul> |
| <li>STATE_SYSTEM_UNAVAILABLE (when enabled is false)</li> |
| <li>STATE_SYSTEM_FOCUSABLE (when enabled is true)</li> |
| <li>STATE_SYSTEM_FOCUSED |
| (when enabled is true and the TabBar has focus)</li> |
| </ul> |
| </p> |
| <p>The State of a tab in a TabBar is a combination of: |
| <ul> |
| <li>STATE_SYSTEM_FOCUSED</li> |
| <li>STATE_SYSTEM_PRESSED</li> |
| </ul> |
| </p> |
| <p>When the State of the TabBar or one of its tabs changes, |
| a TabBar dispatches the MSAA event EVENT_OBJECT_STATECHANGE |
| with the proper childID for the tab or 0 for itself.</p> |
| <p> |
| <b>Value</b> |
| </p> |
| <p>A TabBar, or a tab in a TabBar, does not have an MSAA Value.</p> |
| <p> |
| <b>Location</b> |
| </p> |
| <p>The MSAA Location of a TabBar, or a tab in a TabBar, |
| is its bounding rectangle.</p> |
| <p> |
| <b>Default Action</b> |
| </p> |
| <p>A TabBar does not have an MSAA DefaultAction.</p> |
| <p>The DefaultAction of a tab in a TabBar is "Switch". |
| When it is performed, the given tab is pressed.</p> |
| <p> |
| <b>Focus</b> |
| </p> |
| <p>Both the TabBar and its individual tabs accept focus. |
| When they do so it dispatches the MSAA event EVENT_OBJECT_FOCUS. |
| A tab is not automatically pressed |
| when focused through arrow key navigation. |
| To press a focused tab, the user must press the spacebar.</p> |
| <p> |
| <b>Selection</b> |
| </p> |
| <p>MSAA Selection will press the tab |
| corresponding to the specified childID. |
| Only one tab can be pressed at a time.</p> |
