   2 If the container is resized, all anchored items are automatically rerendered according to their\r

   4 <p>This class is intended to be extended or created via the layout:'anchor' <a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">Ext.Container.layout</a>\r
   5 config, and should generally not need to be created directly via the new keyword.</p>\r
   6 <p>AnchorLayout does not have any direct config options (other than inherited ones). By default,\r
   7 AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the\r
   8 container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.\r
   9 If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating\r
  10 anchor measurements based on it instead, allowing the container to be sized independently of the anchoring\r
  11 logic if necessary.  For example:</p>\r

  36 containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').\r
  37 The following types of anchor values are supported:<div class="mdetail-params"><ul>\r
  38 <li><b>Percentage</b> : Any value between 1 and 100, expressed as a percentage.<div class="sub-desc">\r
  39 The first anchor is the percentage width that the item should take up within the container, and the\r
  40 second is the percentage height.  For example:<pre><code><i>// two values specified\r</i>
  41 anchor: <em>'100% 50%'</em> <i>// render item complete width of the container and\r</i>
  42                    <i>// 1/2 height of the container\r</i>
  43 <i>// one value specified\r</i>
  44 anchor: <em>'100%'</em>     <i>// the width value; the height will <b>default</b> to auto</i></code></pre></div></li>\r
  45 <li><b>Offsets</b> : Any positive or negative integer value.<div class="sub-desc">\r
  46 This is a raw adjustment where the first anchor is the offset from the right edge of the container,\r
  47 and the second is the offset from the bottom edge. For example:<pre><code><i>// two values specified\r</i>
  48 anchor: <em>'-50 -100'</em> <i>// render item the complete width of the container\r</i>
  49                    <i>// minus 50 pixels and\r</i>
  50                    <i>// the complete height minus 100 pixels.\r</i>
  51 <i>// one value specified\r</i>
  52 anchor: <em>'-50'</em>      <i>// anchor value is assumed to be the right offset value\r</i>
  53                    <i>// bottom offset will <b>default</b> to 0</i></code></pre></div></li>\r
  54 <li><b>Sides</b> : Valid values are <tt>'right'</tt> (or <tt>'r'</tt>) and <tt>'bottom'</tt>\r
  55 (or <tt>'b'</tt>).<div class="sub-desc">\r
  56 Either the container must have a fixed size or an anchorSize config value defined at render time in\r
  57 order for these to have any effect.</div></li>\r
  58 <li><b>Mixed</b> : <div class="sub-desc">\r
  59 Anchor values can also be mixed as needed.  For example, to render the width offset from the container\r
  60 right edge by 50 pixels and 75% of the container's height use:\r
