   2 If the container is resized, all anchored items are automatically rerendered according to their
   3 <b><tt><a href="output/Ext.layout.AnchorLayout.html#Ext.layout.AnchorLayout-anchor" ext:member="anchor" ext:cls="Ext.layout.AnchorLayout">anchor</a></tt></b> rules.</p>
   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>
   5 config, and should generally not need to be created directly via the new keyword.</p>
   6 <p>AnchorLayout does not have any direct config options (other than inherited ones). By default,
   7 AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
   8 container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.
   9 If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating
  10 anchor measurements based on it instead, allowing the container to be sized independently of the anchoring
  11 logic if necessary.  For example:</p>
  12 <pre><code><b>var</b> viewport = <b>new</b> Ext.Viewport({
  13     layout:<em>'anchor'</em>,
  14     anchorSize: {width:800, height:600},

  16         title:<em>'Item 1'</em>,
  17         html:<em>'Content 1'</em>,
  18         width:800,
  19         anchor:<em>'right 20%'</em>
  20     },{
  21         title:<em>'Item 2'</em>,
  22         html:<em>'Content 2'</em>,
  23         width:300,
  24         anchor:<em>'50% 30%'</em>
  25     },{

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