<p>The Focus Manager Node Plugin makes it easy to manage focus among |
|
|
54 |
a Node's descendants. Primarily intended to help with widget development, |
|
|
55 |
the Focus Manager Node Plugin can be used to improve the keyboard |
|
|
56 |
accessibility of widgets.</p> |
|
|
57 |
<p> |
|
|
58 |
When designing widgets that manage a set of descendant controls (i.e. buttons |
|
|
59 |
in a toolbar, tabs in a tablist, menuitems in a menu, etc.) it is important to |
|
|
60 |
limit the number of descendants in the browser's default tab flow. The fewer |
|
|
61 |
number of descendants in the default tab flow, the easier it is for keyboard |
|
|
62 |
users to navigate between widgets by pressing the tab key. When a widget has |
|
|
63 |
focus it should provide a set of shortcut keys (typically the arrow keys) |
|
|
64 |
to move focus among its descendants. |
|
|
65 |
</p> |
|
|
66 |
<p> |
|
|
67 |
To this end, the Focus Manager Node Plugin makes it easy to define a Node's |
|
|
68 |
focusable descendants, define which descendant should be in the default tab |
|
|
69 |
flow, and define the keys that move focus among each descendant. |
|
|
70 |
Additionally, as the CSS |
|
|
71 |
<a href="http://www.w3.org/TR/CSS21/selector.html#x38"><code>:focus</code></a> |
|
|
72 |
pseudo class is not supported on all elements in all |
|
|
73 |
<a href="http://developer.yahoo.com/yui/articles/gbs/">A-Grade browsers</a>, |
|
|
74 |
the Focus Manager Node Plugin provides an easy, cross-browser means of |
|
|
75 |
styling focus. |
