-<div id="cls-Ext.Container"></div>/**\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() {\r
- function formatDate(value){\r
- return value ? value.dateFormat('M d, Y') : '';\r
- };\r
-\r
- var store = new Ext.data.Store({\r
- url: 'get-invoice-data.php',\r
- baseParams: {\r
- startDate: '01/01/2008',\r
- endDate: '01/31/2008'\r
- },\r
- reader: new Ext.data.JsonReader({\r
- record: 'transaction',\r
- idProperty: 'id',\r
- totalRecords: 'total'\r
- }, [\r
- 'customer',\r
- 'invNo',\r
- {name: 'date', type: 'date', dateFormat: 'm/d/Y'},\r
- {name: 'value', type: 'float'}\r
- ])\r
- });\r
-\r
- var grid = new Ext.grid.GridPanel({\r
- title: 'Invoice Report',\r
- bbar: new Ext.PagingToolbar(store),\r
- store: store,\r
- columns: [\r
- {header: "Customer", width: 250, dataIndex: 'customer', sortable: true},\r
- {header: "Invoice Number", width: 120, dataIndex: 'invNo', sortable: true},\r
- {header: "Invoice Date", width: 100, dataIndex: 'date', renderer: formatDate, sortable: true},\r
- {header: "Value", width: 120, dataIndex: 'value', renderer: 'usMoney', sortable: true}\r
- ],\r
- });\r
- store.load();\r
- return grid; // return instantiated component\r
-})();\r
-</code></pre>\r
- * <p>When the above code fragment is passed through the <tt>eval</tt> function in the success handler\r
- * of the Ajax request, the code is executed by the Javascript processor, and the anonymous function\r
- * runs, and returns the instantiated grid component.</p>\r
- * <p>Note: since the code above is <i>generated</i> by a server script, the <tt>baseParams</tt> for\r
- * the Store, the metadata to allow generation of the Record layout, and the ColumnModel\r
- * can all be generated into the code since these are all known on the server.</p>\r

- * <p><b>*Important</b>: In order for child items to be correctly sized and\r

- * <br><p>The sizing and positioning of child {@link items} is the responsibility of\r
- * the Container's layout manager which creates and manages the type of layout\r
- * you have in mind. For example:</p><pre><code>\r

- * {@link Ext.layout.ContainerLayout default layout manager} will be used\r
- * which does nothing but render child components sequentially into the\r
- * Container (no sizing or positioning will be performed in this situation).\r
- * Some container classes implicitly specify a default layout\r
- * (e.g. FormPanel specifies <code>layout:'form'</code>). Other specific\r

+<div id="cls-Ext.Container"></div>/**
+ * @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
+ * <code><b>{@link Ext.Component#autoEl autoEl}</b></code> 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><code>'container'</code></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 <code><b>{@link #layout}</b></code>
+ * 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
+ * <code><b>{@link #layout}</b></code> 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 <code><b>{@link #layout}</b></code> configuration, then the overnested
+ * GridPanel will not be sized as expected.<p>
+ *
+ * <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 <code>eval()</code>, 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 <code>eval</code> 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 <code>baseParams</code> 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>
