Class Ext.grid.PropertyGrid

Note: this config is only used when this Component is rendered by a Container which has been configured to use an AnchorLayout (or subclass thereof). based layout manager, for example:

See Ext.layout.AnchorLayout.anchor also.

The id of a column in this grid that should expand to fill unused space. This value specified here can not be 0.

Note: If the Grid's view is configured with forceFit=true the autoExpandColumn is ignored. See Ext.grid.Column.width for additional details.

See autoExpandMax and autoExpandMin also.

Another option available by default is to specify 'x-plain' which strips all styling except for required attributes for Ext layouts to function (e.g. overflow:hidden). See unstyled also.

The bottom toolbar of the panel. This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button configs to be added to the toolbar. Note that this is not available as a property after render. To access the bottom toolbar after render, use getBottomToolbar.

Note: Although a Toolbar may contain Field components, these will not be updated by a load of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and so are not scanned to collect form items. However, the values will be submitted because form submission parameters are collected from the DOM tree.

A DomHelper element specification object specifying the element structure of this Panel's bbar Element. See bodyCfg also.

A DomHelper element specification object may be specified for any Panel Element.

By default, the Default element in the table below will be used for the html markup to create a child element with the commensurate Default class name (baseCls will be replaced by baseCls):

Panel      Default  Default             Custom      Additional       Additional
Element    element  class               element     class            style
========   ==========================   =========   ==============   ===========
header     div      baseCls+'-header'   headerCfg   headerCssClass   headerStyle
bwrap      div      baseCls+'-bwrap'     bwrapCfg    bwrapCssClass    bwrapStyle
+ tbar     div      baseCls+'-tbar'       tbarCfg     tbarCssClass     tbarStyle
+ body     div      baseCls+'-body'       bodyCfg     bodyCssClass     bodyStyle
+ bbar     div      baseCls+'-bbar'       bbarCfg     bbarCssClass     bbarStyle
+ footer   div      baseCls+'-footer'   footerCfg   footerCssClass   footerStyle

Configuring a Custom element may be used, for example, to force the body Element to use a different form of markup than is created by default. An example of this might be to create a child Panel containing a custom content, such as a header, or forcing centering of all Panel content by having the body be a <center> element:

new Ext.Panel({
    title: 'Message Title',
    renderTo: Ext.getBody(),
    width: 200, height: 130,
    bodyCfg: {
        tag: 'center',
        cls: 'x-panel-body',  // Default class not applied if Custom element specified
        html: 'Message'
    },
    footerCfg: {
        tag: 'h2',
        cls: 'x-panel-footer'        // same as the Default class
        html: 'footer html'
    },
    footerCssClass: 'custom-footer', // additional css class, see addClass
    footerStyle:    'background-color:red' // see bodyStyle
});

The example above also explicitly creates a footer with custom markup and styling applied.

The maximum value in pixels which this BoxComponent will set its height to.

Warning: This will override any size management applied by layout managers.

The maximum value in pixels which this BoxComponent will set its width to.

Warning: This will override any size management applied by layout managers.

The minimum value in pixels which this BoxComponent will set its height to.

Warning: This will override any size management applied by layout managers.

The minimum value in pixels which this BoxComponent will set its width to.

Warning: This will override any size management applied by layout managers.

An array of events that, when fired, should be bubbled to any parent container. See Ext.util.Observable.enableBubble. Defaults to [].

A DomHelper element specification object specifying the element structure of this Panel's bwrap Element. See bodyCfg also.

The CSS class used to to apply to the special clearing div rendered directly after each form field wrapper to provide field clearing (defaults to 'x-form-clear-left').

Note: this config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager (e.g. Ext.form.FormPanel or specifying layout:'form') and either a fieldLabel is specified or isFormField=true is specified.

See Ext.layout.FormLayout.fieldTpl also.

The number of clicks on a cell required to display the cell's editor (defaults to 2).

Setting this option to 'auto' means that mousedown on the selected cell starts editing that cell.

An optional extra CSS class that will be added to this component's container. This can be useful for adding customized styles to the container or any of its children using standard CSS rules. See Ext.layout.ContainerLayout.extraCls also.

Note: ctCls defaults to '' except for the following class which assigns a value by default:

ctCls: 'x-box-layout-ct custom-class'

ddText : '{0} selected row{1}'

Defaults to true to enable deferred row rendering.

This allows the GridPanel to be initially rendered empty, with the expensive update of the row structure deferred so that layouts with GridPanels appear more quickly.

new Ext.Panel({
    ...
    listeners: {
        'afterlayout': {
            fn: function(p){
                p.disable();
            },
            single: true // important, as many layouts can occur
        }
    }
});

true to enable dragging of this Panel (defaults to false).

For custom drag/drop implementations, an Ext.Panel.DD config could also be passed in this config instead of true. Ext.Panel.DD is an internal, undocumented class which moves a proxy Element around in place of the Panel's element, but provides no other behaviour during dragging or on drop. It is a subclass of Ext.dd.DragSource, so behaviour may be added by implementing the interface methods of Ext.dd.DragDrop e.g.:

new Ext.Panel({
    title: 'Drag me',
    x: 100,
    y: 100,
    renderTo: Ext.getBody(),
    floating: true,
    frame: true,
    width: 400,
    height: 200,
    draggable: {
//      Config option of Ext.Panel.DD class.
//      It's a floating Panel, so do not show a placeholder proxy in the original position.
        insertProxy: false,

//      Called for each mousemove event while dragging the DD object.
        onDrag : function(e){
//          Record the x,y position of the drag proxy so that we can
//          position the Panel at end of drag.
            var pel = this.proxy.getEl();
            this.x = pel.getLeft(true);
            this.y = pel.getTop(true);

//          Keep the Shadow aligned if there is one.
            var s = this.panel.getEl().shadow;
            if (s) {
                s.realign(this.x, this.y, pel.getWidth(), pel.getHeight());
            }
        },

//      Called on the mouseup event.
        endDrag : function(e){
            this.panel.setPosition(this.x, this.y);
        }
    }
}).show();

Enables dragging of the selected rows of the GridPanel. Defaults to false.

Setting this to true causes this GridPanel's GridView to create an instance of Ext.grid.GridDragZone. Note: this is available only after the Grid has been rendered as the GridView's dragZone property.

A cooperating DropZone must be created who's implementations of onNodeEnter, onNodeOver, onNodeOut and onNodeDrop are able to process the data which is provided.

A Toolbar object, a Toolbar config, or an array of Buttons/Button configs, describing a Toolbar to be rendered into this Panel's footer element.

After render, the fbar property will be an Toolbar instance.

If buttons are specified, they will supersede the fbar configuration property.

var w = new Ext.Window({
    height: 250,
    width: 500,
    bbar: new Ext.Toolbar({
        items: [{
            text: 'bbar Left'
        },'->',{
            text: 'bbar Right'
        }]
    }),
    buttonAlign: 'left', // anything but 'center' or 'right' and you can use '-', and '->'
                                  // to control the alignment of fbar items
    fbar: [{
        text: 'fbar Left'
    },'->',{
        text: 'fbar Right'
    }]
}).show();

Note: Although a Toolbar may contain Field components, these will not be updated by a load of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and so are not scanned to collect form items. However, the values will be submitted because form submission parameters are collected from the DOM tree.

The label text to display next to this Component (defaults to '').

Note: this config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager (e.g. Ext.form.FormPanel or specifying layout:'form').

Also see hideLabel and Ext.layout.FormLayout.fieldTpl.

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Name'
    }]
});

Note: this config is only used when this Component is rendered by a Container which has been configured to use a BoxLayout. Each child Component with a flex property will be flexed either vertically (by a VBoxLayout) or horizontally (by an HBoxLayout) according to the item's relative flex value compared to the sum of all Components with flex value specified. Any child items that have either a flex = 0 or flex = undefined will not be 'flexed' (the initial size will not be changed).

This property is used to configure the underlying Ext.Layer. Acceptable values for this configuration property are:

A DomHelper element specification object specifying the element structure of this Panel's footer Element. See bodyCfg also.

The template generated for each condition is depicted below:

// frame = false
<div id="developer-specified-id-goes-here" class="x-panel">

    <div class="x-panel-header"><span class="x-panel-header-text">Title: (frame:false)</span></div>

    <div class="x-panel-bwrap">
        <div class="x-panel-body"><p>html value goes here</p></div>
    </div>
</div>

// frame = true (create 9 elements)
<div id="developer-specified-id-goes-here" class="x-panel">
    <div class="x-panel-tl"><div class="x-panel-tr"><div class="x-panel-tc">
        <div class="x-panel-header"><span class="x-panel-header-text">Title: (frame:true)</span></div>
    </div></div></div>

    <div class="x-panel-bwrap">
        <div class="x-panel-ml"><div class="x-panel-mr"><div class="x-panel-mc">
            <div class="x-panel-body"><p>html value goes here</p></div>
        </div></div></div>

        <div class="x-panel-bl"><div class="x-panel-br"><div class="x-panel-bc"/>
        </div></div></div>
</div>

A DomHelper element specification object specifying the element structure of this Panel's header Element. See bodyCfg also.

true to completely hide the label element (label and separator). Defaults to false. By default, even if you do not specify a fieldLabel the space will still be reserved so that the field will line up with other fields that do have labels. Setting this to true will cause the field to not reserve that space.

Note: see the note for clearCls.

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield'
        hideLabel: true
    }]
});

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

Note: the default of 'display' is generally preferred since items are automatically laid out when they are first shown (no sizing is done while hidden).

An example of specifying a custom icon class would be something like:

// specify the property in the config for the class:
     ...
     iconCls: 'my-icon'

// css class that specifies background image to be used as the icon image:
.my-icon { background-image: url(../images/my-icon.gif) 0 6px no-repeat !important; }

The unique id of this component (defaults to an auto-assigned id). You should assign an id if you need to be able to access the component later and you do not have an object reference available (e.g., using Ext.getCmp).

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Note: to avoid complications imposed by a unique id also see itemId and ref.

Note: to access the container of an item see ownerCt.

Note: this config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager (e.g. Ext.form.FormPanel or specifying layout:'form').

An additional CSS class to apply to the div wrapping the form item element of this field. If supplied, itemCls at the field level will override the default itemCls supplied at the container level. The value specified for itemCls will be added to the default class ('x-form-item').

Since it is applied to the item wrapper (see Ext.layout.FormLayout.fieldTpl), it allows you to write standard CSS rules that can apply to the field, the label (if specified), or any other element within the markup for the field.

Note: see the note for fieldLabel.

// Apply a style to the field's label:
<style>
    .required .x-form-item-label {font-weight:bold;color:red;}
</style>

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Name',
        itemCls: 'required' //this label will be styled
    },{
        xtype: 'textfield',
        fieldLabel: 'Favorite Color'
    }]
});

An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with Ext.getCmp, use itemId with Ext.Container.getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container -- avoiding potential conflicts with Ext.ComponentMgr which requires a unique id.

var c = new Ext.Panel({ //
    height: 300,
    renderTo: document.body,
    layout: 'auto',
    items: [
        {
            itemId: 'p1',
            title: 'Panel 1',
            height: 150
        },
        {
            itemId: 'p2',
            title: 'Panel 2',
            height: 150
        }
    ]
})
p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling

Also see id and ref.

Note: to access the container of an item see ownerCt.

The separator to display after the text of each fieldLabel. This property may be configured at various levels. The order of precedence is:

Note: see the note for clearCls.

Also see hideLabel and Ext.layout.FormLayout.fieldTpl.

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    layoutConfig: {
        labelSeparator: '~'   // layout config has lowest priority (defaults to ':')
    },
    labelSeparator: '>>',     // config at container level
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Field 1',
        labelSeparator: '...' // field/component level config supersedes others
    },{
        xtype: 'textfield',
        fieldLabel: 'Field 2' // labelSeparator will be '='
    }]
});

A CSS style specification string to apply directly to this field's label. Defaults to the container's labelStyle value if set (e.g., Ext.layout.FormLayout.labelStyle , or '').

Note: see the note for clearCls.

Also see hideLabel and Ext.layout.FormLayout.fieldTpl.

new Ext.FormPanel({
    height: 100,
    renderTo: Ext.getBody(),
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Name',
        labelStyle: 'font-weight:bold;'
    }]
});

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);
        };
    }
});

var combo = new Ext.form.ComboBox({

    // Collapse combo when its element is clicked on
    plugins: [ new Ext.DomObserver({
        click: function(evt, comp) {
            comp.collapse();
        }
    })],
    store: myStore,
    typeAhead: true,
    mode: 'local',
    triggerAction: 'all'
});

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:

Defaults to:

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

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.

Also see the added and removed events.

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

See Ext.layout.BorderLayout also.

Specify the id of the element, a DOM element or an existing Element that this component will be rendered into.

See render also.

stateEvents: ['columnmove', 'columnresize', 'sortchange', 'groupchange']

These can be any types of events supported by this component, including browser or custom events (e.g., ['click', 'customerchange']).

See Ext.Component.stateful for an explanation of saving and restoring Component state.

See stateful for an explanation of saving and restoring Component state.

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.

This causes the CSS class x-grid3-row-alt to be added to alternate rows of the grid. A default CSS rule is provided which sets a background colour, but you can override this with a rule which either overrides the background-color style using the '!important' modifier, or which uses a CSS selector of higher specificity.

new Ext.Panel({
    title: 'Some Title',
    renderTo: Ext.getBody(),
    width: 400, height: 300,
    layout: 'form',
    items: [{
        xtype: 'textarea',
        style: {
            width: '95%',
            marginBottom: '10px'
        }
    },
        new Ext.Button({
            text: 'Send',
            minWidth: '100',
            style: {
                marginBottom: '10px'
            }
        })
    ]
});

Note: this config is only used when this BoxComponent is a child item of a TabPanel.

The top toolbar of the panel. This can be a Ext.Toolbar object, a toolbar config, or an array of buttons/button configs to be added to the toolbar. Note that this is not available as a property after render. To access the top toolbar after render, use getTopToolbar.

Note: Although a Toolbar may contain Field components, these will not be updated by a load of an ancestor FormPanel. A Panel's toolbars are not part of the standard Container->Component hierarchy, and so are not scanned to collect form items. However, the values will be submitted because form submission parameters are collected from the DOM tree.

A DomHelper element specification object specifying the element structure of this Panel's tbar Element. See bodyCfg also.

A Template used to create tools in the header Element. Defaults to:

new Ext.Template('<div class="x-tool x-tool-{id}">&#160;</div>')

This may may be overridden to provide a custom DOM structure for tools based upon a more complex XTemplate. The template's data is a single tool configuration object (Not the entire Array) as specified in tools. In the following example an <a> tag is used to provide a visual indication when hovering over the tool:

var win = new Ext.Window({
    tools: [{
        id: 'download',
        href: '/MyPdfDoc.pdf'
    }],
    toolTemplate: new Ext.XTemplate(
        '<tpl if="id==\'download\'">',
            '<a class="x-tool x-tool-pdf" href="{href}"></a>',
        '</tpl>',
        '<tpl if="id!=\'download\'">',
            '<div class="x-tool x-tool-{id}">&#160;</div>',
        '</tpl>'
    ),
    width:500,
    height:300,
    closeAction:'hide'
});

Note that the CSS class 'x-tool-pdf' should have an associated style rule which provides an appropriate background image, something like:

a.x-tool-pdf {background-image: url(../shared/extjs/images/pdf.gif)!important;}

Each tool config may contain the following properties:

Note that, apart from the toggle tool which is provided when a panel is collapsible, these tools only provide the visual button. Any required functionality must be provided by adding handlers that implement the necessary behavior.

Example usage:

tools:[{
    id:'refresh',
    qtip: 'Refresh form Data',
    // hidden:true,
    handler: function(event, toolEl, panel){
        // refresh logic
    }
},
{
    id:'help',
    qtip: 'Get Help',
    handler: function(event, toolEl, panel){
        // whatever
    }
}]

For the custom id of 'help' define two relevant css classes with a link to a 15x15 image:

.x-tool-help {background-image: url(images/help.png);}
.x-tool-help-over {background-image: url(images/help_over.png);}
// if using an image sprite:
.x-tool-help {background-image: url(images/help.png) no-repeat 0 0;}
.x-tool-help-over {background-position:-15px 0;}
