*

This object also provides a registry of available Component classes * indexed by a mnemonic code known as the Component's {@link Ext.Component#xtype xtype}. * The {@link Ext.Component#xtype xtype} provides a way to avoid instantiating child Components * when creating a full, nested config object for a complete Ext page.

*

A child Component may be specified simply as a config object * as long as the correct {@link Ext.Component#xtype xtype} is specified so that if and when the Component * needs rendering, the correct type can be looked up for lazy instantiation.

Base class for all Ext components. All subclasses of Component may participate in the automated * Ext component lifecycle of creation, rendering and destruction which is provided by the {@link Ext.Container Container} class. * Components may be added to a Container through the {@link Ext.Container#items items} config option at the time the Container is created, * or they may be added dynamically via the {@link Ext.Container#add add} method.

*

The Component base class has built-in support for basic hide/show and enable/disable behavior.

*

All Components are registered with the {@link Ext.ComponentMgr} on construction so that they can be referenced at any time via * {@link Ext#getCmp}, passing the {@link #id}.

*

All user-developed visual widgets that are required to participate in automated lifecycle and size management should subclass Component (or * {@link Ext.BoxComponent} if managed box model handling is required, ie height and width management).

*

See the Creating new UI controls tutorial for details on how * and to either extend or augment ExtJs base classes to create custom Components.

*

Every component has a specific xtype, which is its Ext-specific type name, along with methods for checking the * xtype like {@link #getXType} and {@link #isXType}. This is the list of all valid xtypes:

For state saving to work, the state manager's provider must have been * set to an implementation of {@link Ext.state.Provider} which overrides the * {@link Ext.state.Provider#set set} and {@link Ext.state.Provider#get get} * methods to save and recall name/value pairs. A built-in implementation, * {@link 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 {@link #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 {@link Ext.state.Manager#set} * which uses the configured {@link Ext.state.Provider} to save the object * keyed by the Component's {@link stateId}, or, if that is not * specified, its {@link #id}.

*

During construction, a stateful Component attempts to restore * its state by calling {@link Ext.state.Manager#get} passing the * {@link #stateId}, or, if that is not specified, the * {@link #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 {@link #beforestaterestore}, {@link #staterestore}, * {@link #beforestatesave} and {@link #statesave} events.

*/ /** * @cfg {String} stateId * The unique id for this component to use for state management purposes * (defaults to the component id if one was set, otherwise null if the * component is using a generated id). *

See {@link #stateful} for an explanation of saving and * restoring Component state.

*/ /** * @cfg {Array} stateEvents *

An array of events that, when fired, should trigger this component to * save its state (defaults to none). stateEvents may be any type * of event supported by this component, including browser or custom events * (e.g., ['click', 'customerchange']).

*

See {@link #stateful} for an explanation of saving and * restoring Component state.

*/ /** * @cfg {Mixed} autoEl *

A tag name or {@link Ext.DomHelper DomHelper} spec used to create the {@link #getEl Element} which will * encapsulate this Component.

*

You do not normally need to specify this. For the base classes {@link Ext.Component}, {@link Ext.BoxComponent}, * and {@link 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'

    cls: 'ux-unordered-list',
    items: {
        xtype: 'box',
        autoEl: 'li',
        html: 'First list item'
    }

How this component should be hidden. Supported values are 'visibility' * (css visibility), 'offsets' (negative offset position) and 'display' * (css display).

*

*/ hideMode : 'display', /** * @cfg {Boolean} hideParent * True to hide and show the component's container when hide/show is called on the component, false to hide * and show the component itself (defaults to false).

Render this Component into the passed HTML element.

*

If you are using a {@link Ext.Container Container} object to house this Component, then * do not use the render method.

*

A Container's child Components are rendered by that Container's * {@link Ext.Container#layout layout} manager when the Container is first rendered.

*

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}, {@link Ext.layout.TableLayout}.

*

If the Container is already rendered when a new child Component is added, you may need to call * the Container's {@link Ext.Container#doLayout 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 {@link Ext.Container#layout 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.

*

Base class for any {@link Ext.Component Component} that is to be sized as a box, using width and height.

*

BoxComponent provides automatic box model adjustments for sizing and positioning and will work correctly * within the Component rendering model.

*

A BoxComponent may be created as a custom Component which encapsulates any HTML element, either a pre-existing * element, or one that is created to your specifications at render time. Usually, to participate in layouts, * a Component will need to be a BoxComponent in order to have its width and height managed.

*

To use a pre-existing element as a BoxComponent, configure it so that you preset the el property to the * element to reference:


var pageHeader = new Ext.BoxComponent({
    el: 'my-header-div'
});
* This may then be {@link Ext.Container#add added} to a {@link Ext.Container Container} as a child item.

*

To create a BoxComponent based around a HTML element to be created at render time, use the * {@link Ext.Component#autoEl autoEl} config option which takes the form of a * {@link Ext.DomHelper DomHelper} specification:


var myImage = new Ext.BoxComponent({
    autoEl: {
        tag: 'img',
        src: '/images/my-image.jpg'
    }
});

* @constructor * @param {Ext.Element/String/Object} config The configuration options. * @xtype box */ Ext.BoxComponent = Ext.extend(Ext.Component, { // Configs below are used for all Components when rendered by BorderLayout. /** * @cfg {String} region

Note: this config is only used when this BoxComponent is rendered * by a Container which has been configured to use the {@link Ext.layout.BorderLayout BorderLayout} * layout manager (e.g. specifying layout:'border').


*

See {@link Ext.layout.BorderLayout} also.

*/ // margins config is used when a BoxComponent is rendered by BorderLayout or BoxLayout. /** * @cfg {Object} margins

Note: this config is only used when this BoxComponent is rendered * by a Container which has been configured to use the {@link Ext.layout.BorderLayout BorderLayout} * or one of the two {@link Ext.layout.BoxLayout 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:

*

*

Defaults to:


     * {top:0, right:0, bottom:0, left:0}
     *
*/ /** * @cfg {Number} x * The local x (left) coordinate for this component if contained within a positioning container. */ /** * @cfg {Number} y * The local y (top) coordinate for this component if contained within a positioning container. */ /** * @cfg {Number} pageX * The page level x coordinate for this component if contained within a positioning container. */ /** * @cfg {Number} pageY * The page level y coordinate for this component if contained within a positioning container. */ /** * @cfg {Number} height * The height of this component in pixels (defaults to auto). * Note to express this dimension as a percentage or offset see {@link Ext.Component#anchor}. */ /** * @cfg {Number} width * The width of this component in pixels (defaults to auto). * Note to express this dimension as a percentage or offset see {@link Ext.Component#anchor}. */ /** * @cfg {Boolean} autoHeight *

True to use height:'auto', false to use fixed height (or allow it to be managed by its parent * Container's {@link Ext.Container#layout 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,
        listeners: {
            beforecollapse: function() {
                w.el.shadow.hide();
            },
            beforeexpand: function() {
                w.el.shadow.hide();
            },
            collapse: function() {
                w.syncShadow();
            },
            expand: function() {
                w.syncShadow();
            }
        }
    }
}).show();
*/ /** * @cfg {Boolean} autoWidth *

True to use width:'auto', false to use fixed width (or allow it to be managed by its parent * Container's {@link Ext.Container#layout 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,
    layout: 'hbox',
    layoutConfig: {
        align: 'stretch'
    },
    defaults: {
        flex: 1
    },
    items: [{
        title: 'Box 1',
    }, {
        title: 'Box 2'
    }, {
        title: 'Box 3'

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.

* * @xtype container */ Ext.Container = Ext.extend(Ext.BoxComponent, { /** * @cfg {Boolean} monitorResize * True to automatically monitor window resize events to handle anything that is sensitive to the current size * of the viewport. This value is typically managed by the chosen {@link #layout} and should not need * to be set manually. */ /** * @cfg {String/Object} layout * 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 specify a 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();
     *
*

Omitting the {@link #layout} config means that 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).

*

The layout manager class for this container may be specified as either as an * Object or as a String:

*
*/ /** * @cfg {Object} layoutConfig * This is a config object containing properties specific to the chosen * {@link #layout} if {@link #layout} * has been specified as a string.

This layout manages multiple child Components, each fitted to the Container, where only a single child Component can be * visible at any given time. This layout style is most commonly used for wizards, tab implementations, etc. * This class is intended to be extended or created via the layout:'card' {@link Ext.Container#layout} config, * and should generally not need to be created directly via the new keyword.

*

The CardLayout's focal method is {@link #setActiveItem}. Since only one panel is displayed at a time, * the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of * the next panel to display. The layout itself does not provide a user interface for handling this navigation, * so that functionality must be provided by the developer.

*

In the following example, a simplistic wizard setup is demonstrated. A button bar is added * to the footer of the containing panel to provide navigation buttons. The buttons will be handled by a * common navigation routine -- for this example, the implementation of that routine has been ommitted since * it can be any type of custom logic. Note that other uses of a CardLayout (like a tab control) would require a * completely different implementation. For serious implementations, a better approach would be to extend * CardLayout to provide the custom functionality needed. Example usage:

* 

var navHandler = function(direction){
    // This routine could contain business logic required to manage the navigation steps.
    // It would call setActiveItem as needed, manage navigation button state, handle any
    // branching logic that might be required, handle alternate actions like cancellation
    // or finalization, etc.  A complete wizard implementation could get pretty
    // sophisticated depending on the complexity required, and should probably be
    // done as a subclass of CardLayout in a real-world implementation.

AnchorLayout does not have any direct config options (other than inherited ones). By default, * AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the * container using the AnchorLayout can supply an anchoring-specific config property of anchorSize. * If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating * anchor measurements based on it instead, allowing the container to be sized independently of the anchoring * logic if necessary. For example:

* 

var viewport = new Ext.Viewport({
    layout:'anchor',
    anchorSize: {width:800, height:600},
    items:[{
        title:'Item 1',
        html:'Content 1',
        width:800,
        anchor:'right 20%'
    },{
        title:'Item 2',
        html:'Content 2',
        width:300,
        anchor:'50% 30%'
    },{
        title:'Item 3',
        html:'Content 3',
        width:600,
        anchor:'-100 50%'
    }]
});
 *
*/ Ext.layout.AnchorLayout = Ext.extend(Ext.layout.ContainerLayout, { /** * @cfg {String} anchor *

This configuation option is to be applied to child items of a container managed by * this layout (ie. configured with layout:'anchor').


* *

This value is what tells the layout how an item should be anchored to the container. items * added to an AnchorLayout accept an anchoring-specific config property of anchor which is a string * containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%'). * The following types of anchor values are supported:

This is the layout style of choice for creating structural layouts in a multi-column format where the width of * each column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content. * This class is intended to be extended or created via the layout:'column' {@link Ext.Container#layout} config, * and should generally not need to be created directly via the new keyword.

*

ColumnLayout does not have any direct config options (other than inherited ones), but it does support a * specific config property of columnWidth that can be included in the config of any panel added to it. The * layout will use the columnWidth (if present) or width of each panel during layout to determine how to size each panel. * If width or columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).

*

The width property is always evaluated as pixels, and must be a number greater than or equal to 1. * The columnWidth property is always evaluated as a percentage, and must be a decimal value greater than 0 and * less than 1 (e.g., .25).

*

The basic rules for specifying column widths are pretty simple. The logic makes two passes through the * set of contained panels. During the first layout pass, all panels that either have a fixed width or none * specified (auto) are skipped, but their widths are subtracted from the overall container width. During the second * pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages based on * the total remaining container width. In other words, percentage width panels are designed to fill the space * left over by all the fixed-width and/or auto-width panels. Because of this, while you can specify any number of columns * with different percentages, the columnWidths must always add up to 1 (or 100%) when added together, otherwise your * layout may not render as expected. Example usage:

* 

// All columns are percentages -- they must add up to 1
var p = new Ext.Panel({
    title: 'Column Layout - Percentage Only',
    layout:'column',
    items: [{
        title: 'Column 1',
        columnWidth: .25 
    },{
        title: 'Column 2',
        columnWidth: .6
    },{
        title: 'Column 3',
        columnWidth: .15
    }]
});

// Mix of width and columnWidth -- all columnWidth values must add up
// to 1. The first column will take up exactly 120px, and the last two
// columns will fill the remaining container width.
var p = new Ext.Panel({
    title: 'Column Layout - Mixed',
    layout:'column',
    items: [{
        title: 'Column 1',
        width: 120
    },{
        title: 'Column 2',
        columnWidth: .8
    },{
        title: 'Column 3',
        columnWidth: .2
    }]

This layout manager is specifically designed for rendering and managing child Components of * {@link Ext.form.FormPanel forms}. It is responsible for rendering the labels of * {@link Ext.form.Field Field}s.

* *

This layout manager is used when a Container is configured with the layout:'form' * {@link Ext.Container#layout layout} config option, and should generally not need to be created directly * via the new keyword. See {@link Ext.Container#layout} for additional details.

* *

In an application, it will usually be preferrable to use a {@link Ext.form.FormPanel FormPanel} * (which is configured with FormLayout as its layout class by default) since it also provides built-in * functionality for {@link Ext.form.BasicForm#doAction loading, validating and submitting} the form.

* *

A {@link Ext.Container Container} using the FormLayout layout manager (e.g. * {@link Ext.form.FormPanel} or specifying layout:'form') can also accept the following * layout-specific config properties:

* *

Any Component (including Fields) managed by FormLayout accepts the following as a config option: *

* *

Any Component managed by FormLayout may be rendered as a form field (with an associated label) by * configuring it with a non-null {@link Ext.Component#fieldLabel fieldLabel}. Components configured * in this way may be configured with the following options which affect the way the FormLayout renders them: *

* *

Example usage:

This layout allows you to easily render content into an HTML table. The total number of columns can be * specified, and rowspan and colspan can be used to create complex layouts within the table. * This class is intended to be extended or created via the layout:'table' {@link Ext.Container#layout} config, * and should generally not need to be created directly via the new keyword.

*

Note that when creating a layout via config, the layout-specific config properties must be passed in via * the {@link Ext.Container#layoutConfig} object which will then be applied internally to the layout. In the * case of TableLayout, the only valid layout config property is {@link #columns}. However, the items added to a * TableLayout can supply the following table-specific config properties:

* *

The basic concept of building up a TableLayout is conceptually very similar to building up a standard * HTML table. You simply add each panel (or "cell") that you want to include along with any span attributes * specified as the special config properties of rowspan and colspan which work exactly like their HTML counterparts. * Rather than explicitly creating and nesting rows and columns as you would in HTML, you simply specify the * total column count in the layoutConfig and start adding panels in their natural order from left to right, * top to bottom. The layout will automatically figure out, based on the column count, rowspans and colspans, * how to position each panel within the table. Just like with HTML tables, your rowspans and colspans must add * up correctly in your overall layout or you'll end up with missing and/or extra cells! Example usage:

* 

// This code will generate a layout table that is 3 columns by 2 rows
// with some spanning included.  The basic layout will be:
// +--------+-----------------+
// |   A    |   B             |
// |        |--------+--------|
// |        |   C    |   D    |
