2458 |
* The array of context arguments for context-sensitive positioning. |
2459 |
* </p> |
2460 |
* |
2461 |
* <p> |
2462 |
* The format of the array is: <code>[contextElementOrId, overlayCorner, contextCorner, arrayOfTriggerEvents (optional), xyOffset (optional)]</code>, the |
2463 |
* the 5 array elements described in detail below: |
2464 |
* </p> |
2465 |
* |
2466 |
* <dl> |
2467 |
* <dt>contextElementOrId <String|HTMLElement></dt> |
2468 |
* <dd>A reference to the context element to which the overlay should be aligned (or it's id).</dd> |
2469 |
* <dt>overlayCorner <String></dt> |
2470 |
* <dd>The corner of the overlay which is to be used for alignment. This corner will be aligned to the |
2471 |
* corner of the context element defined by the "contextCorner" entry which follows. Supported string values are: |
2472 |
* "tr" (top right), "tl" (top left), "br" (bottom right), or "bl" (bottom left).</dd> |
2473 |
* <dt>contextCorner <String></dt> |
2474 |
* <dd>The corner of the context element which is to be used for alignment. Supported string values are the same ones listed for the "overlayCorner" entry above.</dd> |
2475 |
* <dt>arrayOfTriggerEvents (optional) <Array[String|CustomEvent]></dt> |
2476 |
* <dd> |
2477 |
* <p> |
2478 |
* By default, context alignment is a one time operation, aligning the Overlay to the context element when context configuration property is set, or when the <a href="#method_align">align</a> |
2479 |
* method is invoked. However, you can use the optional "arrayOfTriggerEvents" entry to define the list of events which should force the overlay to re-align itself with the context element. |
2480 |
* This is useful in situations where the layout of the document may change, resulting in the context element's position being modified. |
2481 |
* </p> |
2482 |
* <p> |
2483 |
* The array can contain either event type strings for events the instance publishes (e.g. "beforeShow") or CustomEvent instances. Additionally the following |
2484 |
* 3 static container event types are also currently supported : <code>"windowResize", "windowScroll", "textResize"</code> (defined in <a href="#property__TRIGGER_MAP">_TRIGGER_MAP</a> private property). |
2485 |
* </p> |
2486 |
* </dd> |
2487 |
* <dt>xyOffset <Number[]></dt> |
2488 |
* <dd> |
2489 |
* A 2 element Array specifying the X and Y pixel amounts by which the Overlay should be offset from the aligned corner. e.g. [5,0] offsets the Overlay 5 pixels to the left, <em>after</em> aligning the given context corners. |
2490 |
* NOTE: If using this property and no triggers need to be defined, the arrayOfTriggerEvents property should be set to null to maintain correct array positions for the arguments. |
2491 |
* </dd> |
2492 |
* </dl> |
2493 |
* |
2494 |
* <p> |
2495 |
* For example, setting this property to <code>["img1", "tl", "bl"]</code> will |
2496 |
* align the Overlay's top left corner to the bottom left corner of the |
2497 |
* context element with id "img1". |
2498 |
* </p> |
2499 |
* <p> |
2500 |
* Setting this property to <code>["img1", "tl", "bl", null, [0,5]</code> will |
2501 |
* align the Overlay's top left corner to the bottom left corner of the |
2502 |
* context element with id "img1", and then offset it by 5 pixels on the Y axis (providing a 5 pixel gap between the bottom of the context element and top of the overlay). |
2503 |
* </p> |
2504 |
* <p> |
2505 |
* Adding the optional trigger values: <code>["img1", "tl", "bl", ["beforeShow", "windowResize"], [0,5]]</code>, |
2506 |
* will re-align the overlay position, whenever the "beforeShow" or "windowResize" events are fired. |
