46 <p><b><u>Notes</u></b>:</p><div class="mdetail-params"><ul>
47 <li>Any container using the BorderLayout <b>must</b> have a child item with <tt>region:'center'</tt>.
48 The child item in the center region will always be resized to fill the remaining space not used by
49 the other regions in the layout.</li>
50 <li>Any child items with a region of <tt>west</tt> or <tt>east</tt> must have <tt>width</tt> defined
51 (an integer representing the number of pixels that the region should take up).</li>
52 <li>Any child items with a region of <tt>north</tt> or <tt>south</tt> must have <tt>height</tt> defined.</li>
53 <li>The regions of a BorderLayout are <b>fixed at render time</b> and thereafter, its child Components may not be removed or added</b>.  To add/remove
54 Components within a BorderLayout, have them wrapped by an additional Container which is directly
55 managed by the BorderLayout.  If the region is to be collapsible, the Container used directly
56 by the BorderLayout manager should be a Panel.  In the following example a Container (an Ext.Panel)
57 is added to the west region:
58 <div style="margin-left:16px"><pre><code>wrc = <a href="output/Ext.html#Ext-getCmp" ext:member="getCmp" ext:cls="Ext">Ext.getCmp</a>(<em>'west-region-container'</em>);
59 wrc.<a href="output/Ext.Panel.html#Ext.Panel-removeAll" ext:member="removeAll" ext:cls="Ext.Panel">removeAll</a>();
60 wrc.<a href="output/Ext.Container.html#Ext.Container-add" ext:member="add" ext:cls="Ext.Container">add</a>({
61     title: <em>'Added Panel'</em>,
62     html: <em>'Some content'</em>
