-/**\r
- * @class Ext.Resizable\r
- * @extends Ext.util.Observable\r
- * <p>Applies drag handles to an element to make it resizable. The drag handles are inserted into the element \r
- * and positioned absolute. Some elements, such as a textarea or image, don't support this. To overcome that, you can wrap\r
- * the textarea in a div and set "resizeChild" to true (or to the id of the element), <b>or</b> set wrap:true in your config and\r
- * the element will be wrapped for you automatically.</p>\r
- * <p>Here is the list of valid resize handles:</p>\r
- * <pre>\r
-Value Description\r
------- -------------------\r
- 'n' north\r
- 's' south\r
- 'e' east\r
- 'w' west\r
- 'nw' northwest\r
- 'sw' southwest\r
- 'se' southeast\r
- 'ne' northeast\r
- 'all' all\r
-</pre>\r
- * <p>Here's an example showing the creation of a typical Resizable:</p>\r
- * <pre><code>\r
-var resizer = new Ext.Resizable("element-id", {\r
- handles: 'all',\r
- minWidth: 200,\r
- minHeight: 100,\r
- maxWidth: 500,\r
- maxHeight: 400,\r
- pinned: true\r
-});\r
-resizer.on("resize", myHandler);\r
-</code></pre>\r
- * <p>To hide a particular handle, set its display to none in CSS, or through script:<br>\r
- * resizer.east.setDisplayed(false);</p>\r
- * @cfg {Boolean/String/Element} resizeChild True to resize the first child, or id/element to resize (defaults to false)\r
- * @cfg {Array/String} adjustments String "auto" or an array [width, height] with values to be <b>added</b> to the\r
- * resize operation's new size (defaults to [0, 0])\r
- * @cfg {Number} minWidth The minimum width for the element (defaults to 5)\r
- * @cfg {Number} minHeight The minimum height for the element (defaults to 5)\r
- * @cfg {Number} maxWidth The maximum width for the element (defaults to 10000)\r
- * @cfg {Number} maxHeight The maximum height for the element (defaults to 10000)\r
- * @cfg {Boolean} enabled False to disable resizing (defaults to true)\r
- * @cfg {Boolean} wrap True to wrap an element with a div if needed (required for textareas and images, defaults to false)\r
- * @cfg {Number} width The width of the element in pixels (defaults to null)\r
- * @cfg {Number} height The height of the element in pixels (defaults to null)\r
- * @cfg {Boolean} animate True to animate the resize (not compatible with dynamic sizing, defaults to false)\r
- * @cfg {Number} duration Animation duration if animate = true (defaults to .35)\r
- * @cfg {Boolean} dynamic True to resize the element while dragging instead of using a proxy (defaults to false)\r
- * @cfg {String} handles String consisting of the resize handles to display (defaults to undefined)\r
- * @cfg {Boolean} multiDirectional <b>Deprecated</b>. The old style of adding multi-direction resize handles, deprecated\r
- * in favor of the handles config option (defaults to false)\r
- * @cfg {Boolean} disableTrackOver True to disable mouse tracking. This is only applied at config time. (defaults to false)\r
- * @cfg {String} easing Animation easing if animate = true (defaults to 'easingOutStrong')\r
- * @cfg {Number} widthIncrement The increment to snap the width resize in pixels (dynamic must be true, defaults to 0)\r
- * @cfg {Number} heightIncrement The increment to snap the height resize in pixels (dynamic must be true, defaults to 0)\r
- * @cfg {Boolean} pinned True to ensure that the resize handles are always visible, false to display them only when the\r
- * user mouses over the resizable borders. This is only applied at config time. (defaults to false)\r
- * @cfg {Boolean} preserveRatio True to preserve the original ratio between height and width during resize (defaults to false)\r
- * @cfg {Boolean} transparent True for transparent handles. This is only applied at config time. (defaults to false)\r
- * @cfg {Number} minX The minimum allowed page X for the element (only used for west resizing, defaults to 0)\r
- * @cfg {Number} minY The minimum allowed page Y for the element (only used for north resizing, defaults to 0)\r
- * @cfg {Boolean} draggable Convenience to initialize drag drop (defaults to false)\r
- * @constructor\r
- * Create a new resizable component\r
- * @param {Mixed} el The id or element to resize\r
- * @param {Object} config configuration options\r
