Ext.Container

Hierarchy

Subclasses

Files

Base class for any 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 Ext.Panel, Ext.Window and 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 autoEl config option. This is a useful technique when creating embedded column layouts inside 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 layout configuration property.

When either specifying child items of a Container, or dynamically 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 layout schemes. By default, Containers use the 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 layout (e.g. widgets like GridPanels or TreePanels are added to Containers for which no layout has been specified). If a Container is left to use the default 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 Ext.layout.CardLayout, Ext.layout.AnchorLayout, Ext.layout.FormLayout, and 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); // Ext.TabPanel implicitly uses CardLayout
myTabPanel.setActiveTab(myNewGrid);

The example above adds a newly created GridPanel to a TabPanel. Note that a TabPanel uses Ext.layout.CardLayout as its layout manager which means all its child items are sized to 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 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 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 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.

A string component id or the numeric index of the component that should be initially activated within the container's layout on render. For example, activeItem: 'item-1' or activeItem: 0 (index 0 = the first item in the container's collection). activeItem only applies to layout styles that can display items one at a time (like Ext.layout.AccordionLayout, Ext.layout.CardLayout and Ext.layout.FitLayout).

A tag name or DomHelper spec used to create the Element which will encapsulate this Component.

You do not normally need to specify this. For the base classes Ext.Component, Ext.BoxComponent, and Ext.Container, this defaults to 'div'. The more complex Ext classes use a more complex DOM structure created by their own onRender methods.

This is intended to allow the developer to create application-specific utility Components encapsulated by different DOM elements. Example usage:

{
    xtype: 'box',
    autoEl: {
        tag: 'img',
        src: 'http://www.example.com/example.jpg'
    }

True to use height:'auto', false to use fixed height (or allow it to be managed by its parent Container's layout manager. Defaults to false.

Note: Although many components inherit this config option, not all will function as expected with a height of 'auto'. Setting autoHeight:true means that the browser will manage height based on the element's contents, and that Ext will not manage it at all.

If the browser is managing the height, be aware that resizes performed by the browser in response to changes within the structure of the Component cannot be detected. Therefore changes to the height might result in elements needing to be synchronized with the new height. Example:

var w = new Ext.Window({
    title: 'Window',
    width: 600,
    autoHeight: true,
    items: {
        title: 'Collapse Me',
        height: 400,
        collapsible: true,
        border: false,

True to use width:'auto', false to use fixed width (or allow it to be managed by its parent Container's layout manager. Defaults to false.

Note: Although many components inherit this config option, not all will function as expected with a width of 'auto'. Setting autoWidth:true means that the browser will manage width based on the element's contents, and that Ext will not manage it at all.

If the browser is managing the width, be aware that resizes performed by the browser in response to changes within the structure of the Component cannot be detected. Therefore changes to the width might result in elements needing to be synchronized with the new width. For example, where the target element is:

<div id='grid-container' style='margin-left:25%;width:50%'></div>

A Panel rendered into that target element must listen for browser window resize in order to relay its child items when the browser changes its width:

var myPanel = new Ext.Panel({
    renderTo: 'grid-container',
    monitorResize: true, // relay on browser resize
    title: 'Panel',
    height: 400,
    autoWidth: true,

This option is a means of applying default settings to all added items whether added through the items config or via the add or insert methods.

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 contained Ext.Panel items, you could pass: defaults: {bodyStyle:'padding:15px'}.

Usage:

defaults: {               // defaults are applied to items, not the container
    autoScroll:true
},
items: [
    {
        xtype: 'panel',   // defaults do not have precedence over
        id: 'panel1',     // options in config objects, so the defaults
        autoScroll: false // will not be applied here, panel1 will be autoScroll:false
    },
    new Ext.Panel({       // defaults do have precedence over options
        id: 'panel2',     // options in components, so the defaults

** IMPORTANT: be sure to specify a <code>layout</code> if needed ! **

A single item, or an array of child Components to be added to this container, for example:

// specifying a single item
items: {...},
layout: 'fit',    // specify a layout!

// specifying multiple items
items: [{...}, {...}],
layout: 'anchor', // specify a layout!

Each item may be:

  • any type of object based on Ext.Component
  • a fully instanciated object or
  • an object literal that:
    • has a specified xtype
    • the Ext.Component.xtype specified is associated with the Component desired and should be chosen from one of the available xtypes as listed in Ext.Component.
    • If an xtype is not explicitly specified, the defaultType for that Container is used.
    • will be "lazily instanciated", avoiding the overhead of constructing a fully instanciated Component object

Notes:

  • Ext uses lazy rendering. Child Components will only be rendered should it become necessary. Items are automatically laid out when they are first shown (no sizing is done while hidden), or in response to a doLayout call.
  • Do not specify contentEl/ html with items.

*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 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 layout configuration is not explicitly specified for a general purpose container (e.g. Container or Panel) the 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:

  • Specify as an Object
    • Example usage:
    • layout: {
          type: 'vbox',
          padding: '5',
          align: 'left'
      }
      
    • type

    • The layout type to be used for this container. If not specified, a default Ext.layout.ContainerLayout will be created and used.


      Valid layout type values are:

    • Layout specific configuration properties

    • Additional layout specific configuration properties may also be specified. For complete details regarding the valid config options for each layout type, see the layout class corresponding to the type specified.

  • Specify as a String
    • Example usage:
    • layout: 'vbox',
      layoutConfig: {
          padding: '5',
          align: 'left'
      }

    (optional)

    A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.


    DOM events from ExtJs Components


    While some ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this

    is usually only done when extra value can be added. For example the DataView's click event passing the node clicked on. To access DOM events directly from a Component's HTMLElement, listeners must be added to the Element after the Component has been rendered. A plugin can simplify this step:

    // Plugin is configured with a listeners config object.
    // The Component is appended to the argument list of all handler functions.
    Ext.DomObserver = Ext.extend(Object, {
        constructor: function(config) {
            this.listeners = config.listeners ? config.listeners : config;
        },
    
        // Component passes itself into plugin's init method
        init: function(c) {
            var p, l = this.listeners;
            for (p in l) {
                if (Ext.isFunction(l[p])) {
                    l[p] = this.createHandler(l[p], c);
                } else {
                    l[p].fn = this.createHandler(l[p].fn, c);
                }
            }
    
            // Add the listeners to the Element immediately following the render call
            c.render = c.render.createSequence(function() {
                var e = c.getEl();
                if (e) {
                    e.on(l);
                }
            });
        },
    
        createHandler: function(fn, c) {
            return function(e) {
                fn.call(this, e, c);
            };
        }
    });

    Note: this config is only used when this BoxComponent is rendered by a Container which has been configured to use the BorderLayout or one of the two BoxLayout subclasses.

    An object containing margins to apply to this BoxComponent in the format:

    {
        top: (top margin),
        right: (right margin),
        bottom: (bottom margin),
        left: (left margin)
    }

    May also be a string containing space-separated, numeric margin values. The order of the sides associated with each value matches the way CSS processes margin values:

    • If there is only one value, it applies to all sides.
    • If there are two values, the top and bottom borders are set to the first value and the right and left are set to the second.
    • If there are three values, the top is set to the first value, the left and right are set to the second, and the bottom is set to the third.
    • If there are four values, they apply to the top, right, bottom, and left, respectively.

    Defaults to:

    {top:0, right:0, bottom:0, left:0}

    An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component. When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.

    A path specification, relative to the Component's ownerCt specifying into which ancestor Container to place a named reference to this Component.

    The ancestor axis can be traversed by using '/' characters in the path. For example, to put a reference to a Toolbar Button into the Panel which owns the Toolbar:

    var myGrid = new Ext.grid.EditorGridPanel({
        title: 'My EditorGridPanel',
        store: myStore,
        colModel: myColModel,
        tbar: [{
            text: 'Save',
            handler: saveChanges,
            disabled: true,
            ref: '../saveButton'
        }],
        listeners: {
            afteredit: function() {
    //          The button reference is in the GridPanel
                myGrid.saveButton.enable();
            }
        }
    });
    

    In the code above, if the ref had been 'saveButton' the reference would have been placed into the Toolbar. Each '/' in the ref moves up one level from the Component's ownerCt.

    A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. ...

    A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. The component must have either a stateId or id assigned for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a component.

    For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available.

    To set the state provider for the current page:

    Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
        expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
    }));
    

    A stateful Component attempts to save state when one of the events listed in the stateEvents configuration fires.

    To save state, a stateful Component first serializes its state by calling getState. By default, this function does nothing. The developer must provide an implementation which returns an object hash which represents the Component's restorable state.

    The value yielded by getState is passed to Ext.state.Manager.set which uses the configured Ext.state.Provider to save the object keyed by the Component's stateId, or, if that is not specified, its id.

    During construction, a stateful Component attempts to restore its state by calling Ext.state.Manager.get passing the stateId, or, if that is not specified, the id.

    The resulting object is passed to applyState. The default implementation of applyState simply copies properties into the object, but a developer may override this to support more behaviour.

    You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events.

    Description :


    Notes :

    • If the Container is already rendered when add is called, you may need to call doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once. For example:
      var tb = new Ext.Toolbar();
      tb.render(document.body);  // toolbar is rendered
      tb.add({text:'Button 1'}); // add multiple items (defaultType for Toolbar is 'button')
      tb.add({text:'Button 2'});
      tb.doLayout();             // refresh the layout

        Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.
      • target : Observable
        Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

      Combining Options
      Using the options argument, it is possible to combine different types of listeners:

      A delayed, one-time listener.

      myDataView.on('click', this.onClick, this, {
      single: true,
      delay: 100
      });

      Attaching multiple handlers in 1 call
      The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers.

      myGridPanel.on({
      'click' : {
          fn: this.onClick,
          scope: this,
          delay: 100
      },
      'mouseover' : {
          fn: this.onMouseOver,
          scope: this
      },
      'mouseout' : {
          fn: this.onMouseOut,
          scope: this
      }
      });

      Or a shorthand syntax:

      myGridPanel.on({
      'click' : this.onClick,
      'mouseover' : this.onMouseOver,
      'mouseout' : this.onMouseOut,
       scope: this
      });

            Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

            Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

            This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

            Example:

            Ext.override(Ext.form.Field, {
                //  Add functionality to Field's initComponent to enable the change event to bubble
                initComponent : Ext.form.Field.prototype.initComponent.createSequence(function() {
                    this.enableBubble('change');
                }),
            
                //  We know that we want Field's events to bubble directly to the FormPanel.
                getBubbleTarget : function() {
                    if (!this.formPanel) {
                        this.formPanel = this.findParentByType('form');
                    }
                    return this.formPanel;
                }
            });
            
            var myForm = new Ext.formPanel({
                title: 'User Details',
                items: [{
                    ...
                }],
                listeners: {
                    change: function() {
                        // Title goes red if form has been modified.
                        myForm.header.setStyle('color', 'red');
                    }

                            Returns the Ext.Element which encapsulates this Component.

                            This will usually be a <DIV> element created by the class's onRender method, but that may be overridden using the autoEl config.


                            Note: this element will not be available until this Component has been rendered.


                            To add listeners for DOM events to this Component (as opposed to listeners for this Component's own Observable events), see the listeners config for a suggestion, or use a render listener directly:

                            new Ext.Panel({
                                title: 'The Clickable Panel',
                                listeners: {
                                    render: function(p) {
                                        // Append the Panel to the click handler's argument list.
                                        p.getEl().on('click', handlePanelClick.createDelegate(null, [p], true));
                                    },
                                    single: true  // Remove the listener after first invocation
                                }

                                      Returns the outermost Element of this Component which defines the Components overall size.

                                      Usually this will return the same Element as getEl, but in some cases, a Component may have some more wrapping Elements around its main active Element.

                                      An example is a ComboBox. It is encased in a wrapping Element which contains both the <input> Element (which is what would be returned by its getEl method, and the trigger button Element. This Element is returned as the resizeEl.

                                          If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

                                              The child Component to insert.

                                              Ext uses lazy rendering, and will only render the inserted Component should it become necessary.

                                              A Component config object may be passed in order to avoid the overhead of constructing a real Component object if lazy rendering might mean that the inserted Component will not be rendered immediately. To take advantage of this 'lazy instantiation', set the Ext.Component.xtype config property to the registered type of the Component wanted.

                                              For a list of all available xtypes, see Ext.Component.

                                              Tests whether or not this Component is of a specific xtype. ...

                                              Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended from the xtype (default) or whether it is directly of the xtype specified (shallow = true).

                                              If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

                                              For a list of all available xtypes, see the Ext.Component header.

                                              Example usage:

                                              var t = new Ext.form.TextField();
                                              var isText = t.isXType('textfield');        // true
                                              var isBoxSubclass = t.isXType('box');       // true, descended from BoxComponent
                                              var isBoxInstance = t.isXType('box', true); // false, not a direct BoxComponent instance

                                              • shallow : Boolean (optional)

                                                False to check whether this Component is descended from the xtype (this is the default), or true to check whether this Component is directly of the specified xtype.

                                                      • eventName : String

                                                        The type of event the handler was associated with.

                                                      • handler : Function

                                                        The handler to remove. This must be a reference to the function passed into the addListener call.

                                                      • scope : Object (optional)

                                                        The scope originally specified for the handler.

                                                      ( [container], [position] ) : Ext.Componentchainable
                                                      Render this Component into the passed HTML element. ...

                                                      Render this Component into the passed HTML element.

                                                      If you are using a Container object to house this Component, then do not use the render method.

                                                      A Container's child Components are rendered by that Container's layout manager when the Container is first rendered.

                                                      Certain layout managers allow dynamic addition of child components. Those that do include Ext.layout.CardLayout, Ext.layout.AnchorLayout, Ext.layout.FormLayout, Ext.layout.TableLayout.

                                                      If the Container is already rendered when a new child Component is added, you may need to call the Container's doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once.

                                                      When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must configure the Container with a layout manager which creates and manages the type of layout you have in mind.

                                                      Omitting the Container's layout config means that a basic layout manager is used which does nothing but render child components sequentially into the Container. No sizing or positioning will be performed in this situation.
