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.
- * - *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
- * {@link Ext.Component#autoEl autoEl}
config option. This is a useful technique when creating
- * embedded {@link Ext.layout.ColumnLayout column} layouts inside {@link Ext.form.FormPanel FormPanels}
- * for example.
The code below illustrates both how to explicitly create a Container, and how to implicitly
- * create one using the 'container'
xtype:
-// 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'
- }
- }]
-});
- *
- * Layout
- *Container classes delegate the rendering of child Components to a layout
- * manager class which must be configured into the Container using the
- * {@link #layout}
configuration property.
When either specifying child {@link #items}
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
- * {@link #layout}
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 does not apply any sizing at all.
A common mistake is when a developer neglects to specify a
- * {@link #layout}
(e.g. widgets like GridPanels or
- * TreePanels are added to Containers for which no {@link #layout}
- * 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.
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:
-// 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);
- *
- * 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. - *
Overnesting is a common problem.
- * An example of overnesting occurs when a GridPanel is added to a TabPanel
- * by wrapping the GridPanel inside a wrapping Panel (that has no
- * {@link #layout}
specified) and then add that wrapping Panel
- * to the TabPanel. The point to realize is that a GridPanel is a
- * Component which can be added directly to a Container. If the wrapping Panel
- * has no {@link #layout}
configuration, then the overnested
- * GridPanel will not be sized as expected.
- * - *
Adding via remote configuration
- * - *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: - *
-// 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");
- }
-});
-
- * The server script needs to return an executable Javascript statement which, when processed
- * using eval()
, will return either a config object with an {@link Ext.Component#xtype xtype},
- * or an instantiated Component. The server might return this for example:
-(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
-})();
-
- * When the above code fragment is passed through the eval
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.
Note: since the code above is generated by a server script, the baseParams
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.
{@link #layout}
and should not need
- * to be set manually.

- /**
- * @cfg {String/Object} layout
- * *Important: In order for child items to be correctly sized and
- * positioned, typically a layout manager must be specified through
- * the layout
configuration option.
The sizing and positioning of child {@link items} is the responsibility of - * the Container's layout manager which creates and manages the type of layout - * you have in mind. For example:
-new Ext.Window({
- width:300, height: 300,
- layout: 'fit', // explicitly set layout manager: override the default (layout:'auto')
- items: [{
- title: 'Panel inside a Window'
- }]
-}).show();
- *
- * If the {@link #layout} configuration is not explicitly specified for
- * a general purpose container (e.g. Container or Panel) the
- * {@link Ext.layout.ContainerLayout default layout manager} will be used
- * which does nothing but render child components sequentially into the
- * Container (no sizing or positioning will be performed in this situation).
- * Some container classes implicitly specify a default layout
- * (e.g. FormPanel specifies layout:'form'
). Other specific
- * purpose classes internally specify/manage their internal layout (e.g.
- * GridPanel, TabPanel, TreePanel, Toolbar, Menu, etc.).
layout
may be specified as either as an Object or
- * as a String:
-layout: {
- type: 'vbox',
- padding: '5',
- align: 'left'
-}
-
- *
- * type
The layout type to be used for this container. If not specified, - * a default {@link Ext.layout.ContainerLayout} will be created and used.
- *Valid layout type
values are:
{@link Ext.layout.AbsoluteLayout absolute}
{@link Ext.layout.AccordionLayout accordion}
{@link Ext.layout.AnchorLayout anchor}
{@link Ext.layout.ContainerLayout auto}
Default{@link Ext.layout.BorderLayout border}
{@link Ext.layout.CardLayout card}
{@link Ext.layout.ColumnLayout column}

{@link Ext.layout.TableLayout table}
{@link Ext.layout.ToolbarLayout toolbar}

- *If an added item is a config object, and not an instantiated Component, then the default properties are - * unconditionally applied. If the added item is an instantiated Component, then the default properties are - * applied conditionally so as not to override existing properties in the item.
- *If the defaults option is specified as a function, then the function will be called using this Container as the
- * scope (this
reference) and passing the added item as the first parameter. Any resulting object
- * from that call is then applied to the item as default properties.
For example, to automatically apply padding to the body of each of a set of
