-/**
- * @class Ext.Container
- * @extends Ext.BoxComponent
- * <p>Base class for any {@link Ext.BoxComponent} that may contain other Components. Containers handle the
- * basic behavior of containing items, namely adding, inserting and removing items.</p>
- *
- * <p>The most commonly used Container classes are {@link Ext.Panel}, {@link Ext.Window} and {@link Ext.TabPanel}.
- * If you do not need the capabilities offered by the aforementioned classes you can create a lightweight
- * Container to be encapsulated by an HTML element to your specifications by using the
- * <tt><b>{@link Ext.Component#autoEl autoEl}</b></tt> config option. This is a useful technique when creating
- * embedded {@link Ext.layout.ColumnLayout column} layouts inside {@link Ext.form.FormPanel FormPanels}
- * for example.</p>
- *
- * <p>The code below illustrates both how to explicitly create a Container, and how to implicitly
- * create one using the <b><tt>'container'</tt></b> xtype:<pre><code>
-// explicitly create a Container
-var embeddedColumns = new Ext.Container({
- autoEl: 'div', // This is the default
- layout: 'column',
- defaults: {
- // implicitly create Container by specifying xtype
- xtype: 'container',
- autoEl: 'div', // This is the default.
- layout: 'form',
- columnWidth: 0.5,
- style: {
- padding: '10px'
- }
- },
-// The two items below will be Ext.Containers, each encapsulated by a <DIV> element.
- items: [{
- items: {
- xtype: 'datefield',
- name: 'startDate',
- fieldLabel: 'Start date'
- }
- }, {
- items: {
- xtype: 'datefield',
- name: 'endDate',
- fieldLabel: 'End date'
- }
- }]
-});</code></pre></p>
- *
- * <p><u><b>Layout</b></u></p>
- * <p>Container classes delegate the rendering of child Components to a layout
- * manager class which must be configured into the Container using the
- * <code><b>{@link #layout}</b></code> configuration property.</p>
- * <p>When either specifying child <code>{@link #items}</code> of a Container,
- * or dynamically {@link #add adding} Components to a Container, remember to
- * consider how you wish the Container to arrange those child elements, and
- * whether those child elements need to be sized using one of Ext's built-in
- * <b><code>{@link #layout}</code></b> schemes. By default, Containers use the
- * {@link Ext.layout.ContainerLayout ContainerLayout} scheme which only
- * renders child components, appending them one after the other inside the
- * Container, and <b>does not apply any sizing</b> at all.</p>
- * <p>A common mistake is when a developer neglects to specify a
- * <b><code>{@link #layout}</code></b> (e.g. widgets like GridPanels or
- * TreePanels are added to Containers for which no <tt><b>{@link #layout}</b></tt>
- * has been specified). If a Container is left to use the default
- * {@link Ext.layout.ContainerLayout ContainerLayout} scheme, none of its
- * child components will be resized, or changed in any way when the Container
- * is resized.</p>
- * <p>Certain layout managers allow dynamic addition of child components.
- * Those that do include {@link Ext.layout.CardLayout},
- * {@link Ext.layout.AnchorLayout}, {@link Ext.layout.FormLayout}, and
- * {@link Ext.layout.TableLayout}. For example:<pre><code>
-// Create the GridPanel.
-var myNewGrid = new Ext.grid.GridPanel({
- store: myStore,
- columns: myColumnModel,
- title: 'Results', // the title becomes the title of the tab
-});
-
-myTabPanel.add(myNewGrid); // {@link Ext.TabPanel} implicitly uses {@link Ext.layout.CardLayout CardLayout}
-myTabPanel.{@link Ext.TabPanel#setActiveTab setActiveTab}(myNewGrid);
- * </code></pre></p>
- * <p>The example above adds a newly created GridPanel to a TabPanel. Note that
- * a TabPanel uses {@link Ext.layout.CardLayout} as its layout manager which
- * means all its child items are sized to {@link Ext.layout.FitLayout fit}
- * exactly into its client area.
- * <p><b><u>Overnesting is a common problem</u></b>.
- * An example of overnesting occurs when a GridPanel is added to a TabPanel
- * by wrapping the GridPanel <i>inside</i> a wrapping Panel (that has no
- * <tt><b>{@link #layout}</b></tt> specified) and then add that wrapping Panel
- * to the TabPanel. The point to realize is that a GridPanel <b>is</b> a
- * Component which can be added directly to a Container. If the wrapping Panel
- * has no <tt><b>{@link #layout}</b></tt> configuration, then the overnested
- * GridPanel will not be sized as expected.<p>
-</code></pre>
- *
- * <p><u><b>Adding via remote configuration</b></u></p>
- *
- * <p>A server side script can be used to add Components which are generated dynamically on the server.
- * An example of adding a GridPanel to a TabPanel where the GridPanel is generated by the server
- * based on certain parameters:
- * </p><pre><code>
-// execute an Ajax request to invoke server side script:
-Ext.Ajax.request({
- url: 'gen-invoice-grid.php',
- // send additional parameters to instruct server script
- params: {
- startDate: Ext.getCmp('start-date').getValue(),
- endDate: Ext.getCmp('end-date').getValue()
- },
- // process the response object to add it to the TabPanel:
- success: function(xhr) {
- var newComponent = eval(xhr.responseText); // see discussion below
- myTabPanel.add(newComponent); // add the component to the TabPanel
- myTabPanel.setActiveTab(newComponent);
- },
- failure: function() {
- Ext.Msg.alert("Grid create failed", "Server communication failure");
- }
-});
-</code></pre>
- * <p>The server script needs to return an executable Javascript statement which, when processed
- * using <tt>eval()</tt>, will return either a config object with an {@link Ext.Component#xtype xtype},
- * or an instantiated Component. The server might return this for example:</p><pre><code>
-(function() {
- function formatDate(value){
- return value ? value.dateFormat('M d, Y') : '';
- };
-
- var store = new Ext.data.Store({
- url: 'get-invoice-data.php',
- baseParams: {
- startDate: '01/01/2008',
- endDate: '01/31/2008'
- },
- reader: new Ext.data.JsonReader({
- record: 'transaction',
- idProperty: 'id',
- totalRecords: 'total'
- }, [
- 'customer',
- 'invNo',
- {name: 'date', type: 'date', dateFormat: 'm/d/Y'},
- {name: 'value', type: 'float'}
- ])
- });
-
- var grid = new Ext.grid.GridPanel({
- title: 'Invoice Report',
- bbar: new Ext.PagingToolbar(store),
- store: store,
- columns: [
- {header: "Customer", width: 250, dataIndex: 'customer', sortable: true},
- {header: "Invoice Number", width: 120, dataIndex: 'invNo', sortable: true},
- {header: "Invoice Date", width: 100, dataIndex: 'date', renderer: formatDate, sortable: true},
- {header: "Value", width: 120, dataIndex: 'value', renderer: 'usMoney', sortable: true}
- ],
- });
- store.load();
- return grid; // return instantiated component
-})();
-</code></pre>
- * <p>When the above code fragment is passed through the <tt>eval</tt> function in the success handler
- * of the Ajax request, the code is executed by the Javascript processor, and the anonymous function
- * runs, and returns the instantiated grid component.</p>
- * <p>Note: since the code above is <i>generated</i> by a server script, the <tt>baseParams</tt> for
- * the Store, the metadata to allow generation of the Record layout, and the ColumnModel
- * can all be generated into the code since these are all known on the server.</p>

+/**\r
+ * @class Ext.Container\r
+ * @extends Ext.BoxComponent\r
+ * <p>Base class for any {@link Ext.BoxComponent} that may contain other Components. Containers handle the\r
+ * basic behavior of containing items, namely adding, inserting and removing items.</p>\r
+ *\r
+ * <p>The most commonly used Container classes are {@link Ext.Panel}, {@link Ext.Window} and {@link Ext.TabPanel}.\r
+ * If you do not need the capabilities offered by the aforementioned classes you can create a lightweight\r
+ * Container to be encapsulated by an HTML element to your specifications by using the\r
+ * <tt><b>{@link Ext.Component#autoEl autoEl}</b></tt> config option. This is a useful technique when creating\r
+ * embedded {@link Ext.layout.ColumnLayout column} layouts inside {@link Ext.form.FormPanel FormPanels}\r
+ * for example.</p>\r
+ *\r
+ * <p>The code below illustrates both how to explicitly create a Container, and how to implicitly\r
+ * create one using the <b><tt>'container'</tt></b> xtype:<pre><code>\r
+// explicitly create a Container\r
+var embeddedColumns = new Ext.Container({\r
+ autoEl: 'div', // This is the default\r
+ layout: 'column',\r
+ defaults: {\r
+ // implicitly create Container by specifying xtype\r
+ xtype: 'container',\r
+ autoEl: 'div', // This is the default.\r
+ layout: 'form',\r
+ columnWidth: 0.5,\r
+ style: {\r
+ padding: '10px'\r
+ }\r
+ },\r
+// The two items below will be Ext.Containers, each encapsulated by a <DIV> element.\r
+ items: [{\r
+ items: {\r
+ xtype: 'datefield',\r
+ name: 'startDate',\r
+ fieldLabel: 'Start date'\r
+ }\r
+ }, {\r
+ items: {\r
+ xtype: 'datefield',\r
+ name: 'endDate',\r
+ fieldLabel: 'End date'\r
+ }\r
+ }]\r
+});</code></pre></p>\r
+ *\r
+ * <p><u><b>Layout</b></u></p>\r
+ * <p>Container classes delegate the rendering of child Components to a layout\r
+ * manager class which must be configured into the Container using the\r
+ * <code><b>{@link #layout}</b></code> configuration property.</p>\r
+ * <p>When either specifying child <code>{@link #items}</code> of a Container,\r
+ * or dynamically {@link #add adding} Components to a Container, remember to\r
+ * consider how you wish the Container to arrange those child elements, and\r
+ * whether those child elements need to be sized using one of Ext's built-in\r
+ * <b><code>{@link #layout}</code></b> schemes. By default, Containers use the\r
+ * {@link Ext.layout.ContainerLayout ContainerLayout} scheme which only\r
+ * renders child components, appending them one after the other inside the\r
+ * Container, and <b>does not apply any sizing</b> at all.</p>\r
+ * <p>A common mistake is when a developer neglects to specify a\r
+ * <b><code>{@link #layout}</code></b> (e.g. widgets like GridPanels or\r
+ * TreePanels are added to Containers for which no <tt><b>{@link #layout}</b></tt>\r
+ * has been specified). If a Container is left to use the default\r
+ * {@link Ext.layout.ContainerLayout ContainerLayout} scheme, none of its\r
+ * child components will be resized, or changed in any way when the Container\r
+ * is resized.</p>\r
+ * <p>Certain layout managers allow dynamic addition of child components.\r
+ * Those that do include {@link Ext.layout.CardLayout},\r
+ * {@link Ext.layout.AnchorLayout}, {@link Ext.layout.FormLayout}, and\r
+ * {@link Ext.layout.TableLayout}. For example:<pre><code>\r
+// Create the GridPanel.\r
+var myNewGrid = new Ext.grid.GridPanel({\r
+ store: myStore,\r
+ columns: myColumnModel,\r
+ title: 'Results', // the title becomes the title of the tab\r
+});\r
+\r
+myTabPanel.add(myNewGrid); // {@link Ext.TabPanel} implicitly uses {@link Ext.layout.CardLayout CardLayout}\r
+myTabPanel.{@link Ext.TabPanel#setActiveTab setActiveTab}(myNewGrid);\r
+ * </code></pre></p>\r
+ * <p>The example above adds a newly created GridPanel to a TabPanel. Note that\r
+ * a TabPanel uses {@link Ext.layout.CardLayout} as its layout manager which\r
+ * means all its child items are sized to {@link Ext.layout.FitLayout fit}\r
+ * exactly into its client area.\r
+ * <p><b><u>Overnesting is a common problem</u></b>.\r
+ * An example of overnesting occurs when a GridPanel is added to a TabPanel\r
+ * by wrapping the GridPanel <i>inside</i> a wrapping Panel (that has no\r
+ * <tt><b>{@link #layout}</b></tt> specified) and then add that wrapping Panel\r
+ * to the TabPanel. The point to realize is that a GridPanel <b>is</b> a\r
+ * Component which can be added directly to a Container. If the wrapping Panel\r
+ * has no <tt><b>{@link #layout}</b></tt> configuration, then the overnested\r
+ * GridPanel will not be sized as expected.<p>\r
+ *\r
+ * <p><u><b>Adding via remote configuration</b></u></p>\r
+ *\r
+ * <p>A server side script can be used to add Components which are generated dynamically on the server.\r
+ * An example of adding a GridPanel to a TabPanel where the GridPanel is generated by the server\r
+ * based on certain parameters:\r
+ * </p><pre><code>\r
+// execute an Ajax request to invoke server side script:\r
+Ext.Ajax.request({\r
+ url: 'gen-invoice-grid.php',\r
+ // send additional parameters to instruct server script\r
+ params: {\r
+ startDate: Ext.getCmp('start-date').getValue(),\r
+ endDate: Ext.getCmp('end-date').getValue()\r
+ },\r
+ // process the response object to add it to the TabPanel:\r
+ success: function(xhr) {\r
+ var newComponent = eval(xhr.responseText); // see discussion below\r
+ myTabPanel.add(newComponent); // add the component to the TabPanel\r
+ myTabPanel.setActiveTab(newComponent);\r
+ },\r
+ failure: function() {\r
+ Ext.Msg.alert("Grid create failed", "Server communication failure");\r
+ }\r
+});\r
+</code></pre>\r
+ * <p>The server script needs to return an executable Javascript statement which, when processed\r
+ * using <tt>eval()</tt>, will return either a config object with an {@link Ext.Component#xtype xtype},\r
+ * or an instantiated Component. The server might return this for example:</p><pre><code>\r

+ function formatDate(value){\r
+ return value ? value.dateFormat('M d, Y') : '';\r
+ };\r
+\r
+ var store = new Ext.data.Store({\r

+\r
