- * `Polymer.IronA11yKeysBehavior` provides a normalized interface for processing |
- * keyboard commands that pertain to [WAI-ARIA best practices](http://www.w3.org/TR/wai-aria-practices/#kbd_general_binding). |
- * The element takes care of browser differences with respect to Keyboard events |
- * and uses an expressive syntax to filter key presses. |
- * |
- * Use the `keyBindings` prototype property to express what combination of keys |
- * will trigger the callback. A key binding has the format |
- * `"KEY+MODIFIER:EVENT": "callback"` (`"KEY": "callback"` or |
- * `"KEY:EVENT": "callback"` are valid as well). Some examples: |
- * |
- * keyBindings: { |
- * 'space': '_onKeydown', // same as 'space:keydown' |
- * 'shift+tab': '_onKeydown', |
- * 'enter:keypress': '_onKeypress', |
- * 'esc:keyup': '_onKeyup' |
- * } |
- * |
- * The callback will receive with an event containing the following information in `event.detail`: |
- * |
- * _onKeydown: function(event) { |
- * console.log(event.detail.combo); // KEY+MODIFIER, e.g. "shift+tab" |
- * console.log(event.detail.key); // KEY only, e.g. "tab" |
- * console.log(event.detail.event); // EVENT, e.g. "keydown" |
- * console.log(event.detail.keyboardEvent); // the original KeyboardEvent |
- * } |
- * |
- * Use the `keyEventTarget` attribute to set up event handlers on a specific |
- * node. |
- * |
- * See the [demo source code](https://github.com/PolymerElements/iron-a11y-keys-behavior/blob/master/demo/x-key-aware.html) |
- * for an example. |

-/** |
- * The `iron-iconset-svg` element allows users to define their own icon sets |
- * that contain svg icons. The svg icon elements should be children of the |
- * `iron-iconset-svg` element. Multiple icons should be given distinct id's. |
- * |
- * Using svg elements to create icons has a few advantages over traditional |
- * bitmap graphics like jpg or png. Icons that use svg are vector based so |
- * they are resolution independent and should look good on any device. They |
- * are stylable via css. Icons can be themed, colorized, and even animated. |
- * |
- * Example: |
- * |
- * <iron-iconset-svg name="my-svg-icons" size="24"> |
- * <svg> |
- * <defs> |
- * <g id="shape"> |
- * <rect x="12" y="0" width="12" height="24" /> |
- * <circle cx="12" cy="12" r="12" /> |
- * </g> |
- * </defs> |
- * </svg> |
- * </iron-iconset-svg> |
- * |
- * This will automatically register the icon set "my-svg-icons" to the iconset |
- * database. To use these icons from within another element, make a |
- * `iron-iconset` element and call the `byId` method |
- * to retrieve a given iconset. To apply a particular icon inside an |
- * element use the `applyIcon` method. For example: |
- * |
- * iconset.applyIcon(iconNode, 'car'); |
- * |
- * @element iron-iconset-svg |

-/** |
-Use `Polymer.IronOverlayBehavior` to implement an element that can be hidden or shown, and displays |
-on top of other content. It includes an optional backdrop, and can be used to implement a variety |
-of UI controls including dialogs and drop downs. Multiple overlays may be displayed at once. |
- |
-See the [demo source code](https://github.com/PolymerElements/iron-overlay-behavior/blob/master/demo/simple-overlay.html) |
-for an example. |
- |
-### Closing and canceling |
- |
-An overlay may be hidden by closing or canceling. The difference between close and cancel is user |
-intent. Closing generally implies that the user acknowledged the content on the overlay. By default, |
-it will cancel whenever the user taps outside it or presses the escape key. This behavior is |
-configurable with the `no-cancel-on-esc-key` and the `no-cancel-on-outside-click` properties. |
-`close()` should be called explicitly by the implementer when the user interacts with a control |
-in the overlay element. When the dialog is canceled, the overlay fires an 'iron-overlay-canceled' |
-event. Call `preventDefault` on this event to prevent the overlay from closing. |
- |
-### Positioning |
- |
-By default the element is sized and positioned to fit and centered inside the window. You can |
-position and size it manually using CSS. See `Polymer.IronFitBehavior`. |
- |
-### Backdrop |
- |
-Set the `with-backdrop` attribute to display a backdrop behind the overlay. The backdrop is |
-appended to `<body>` and is of type `<iron-overlay-backdrop>`. See its doc page for styling |
-options. |
- |
-In addition, `with-backdrop` will wrap the focus within the content in the light DOM. |
-Override the [`_focusableNodes` getter](#Polymer.IronOverlayBehavior:property-_focusableNodes) |
-to achieve a different behavior. |
- |
-### Limitations |
- |
-The element is styled to appear on top of other content by setting its `z-index` property. You |
-must ensure no element has a stacking context with a higher `z-index` than its parent stacking |
-context. You should place this element as a child of `<body>` whenever possible. |
