ColumnModel.js

After the data has been read into the client side cache (Store),\nthe ColumnModel is used to configure how and what parts of that data will be displayed in the\nvertical slices (columns) of the grid. The Ext.grid.ColumnModel Class is the default implementation\nof a ColumnModel used by implentations of GridPanel.

\n\n\n

Data is mapped into the store's records and then indexed into the ColumnModel using the\ndataIndex:

\n\n\n

{data source} == mapping ==> {data store} == dataIndex ==> {ColumnModel}\n

\n\n\n

Each Column in the grid's ColumnModel is configured with a\ndataIndex to specify how the data within\neach record in the store is indexed into the ColumnModel.

\n\n\n

There are two ways to initialize the ColumnModel class:

\n\n\n

Initialization Method 1: an Array

\n\n\n

 var colModel = new Ext.grid.ColumnModel([\n    { header: \"Ticker\", width: 60, sortable: true},\n    { header: \"Company Name\", width: 150, sortable: true, id: 'company'},\n    { header: \"Market Cap.\", width: 100, sortable: true},\n    { header: \"$ Sales\", width: 100, sortable: true, renderer: money},\n    { header: \"Employees\", width: 100, sortable: true, resizable: false}\n ]);\n

\n\n\n

The ColumnModel may be initialized with an Array of Ext.grid.Column column configuration\nobjects to define the initial layout / display of the columns in the Grid. The order of each\nExt.grid.Column column configuration object within the specified Array defines the initial\norder of the column display. A Column's display may be initially hidden using the\nhidden config property (and then shown using the column\nheader menu). Fields that are not included in the ColumnModel will not be displayable at all.

\n\n\n

How each column in the grid correlates (maps) to the Ext.data.Record field in the\nStore the column draws its data from is configured through the\ndataIndex. If the\ndataIndex is not explicitly defined (as shown in the\nexample above) it will use the column configuration's index in the Array as the index.

\n\n\n

See Ext.grid.Column for additional configuration options for each column.

\n\n\n

Initialization Method 2: an Object

\n\n\n

In order to use configuration options from Ext.grid.ColumnModel, an Object may be used to\ninitialize the ColumnModel. The column configuration Array will be specified in the columns\nconfig property. The defaults config property can be used to apply defaults\nfor all columns, e.g.:

\n\n\n

 var colModel = new Ext.grid.ColumnModel({\n    columns: [\n        { header: \"Ticker\", width: 60, menuDisabled: false},\n        { header: \"Company Name\", width: 150, id: 'company'},\n        { header: \"Market Cap.\"},\n        { header: \"$ Sales\", renderer: money},\n        { header: \"Employees\", resizable: false}\n    ],\n    defaults: {\n        sortable: true,\n        menuDisabled: true,\n        width: 100\n    },\n    listeners: {\n        hiddenchange: function(cm, colIndex, hidden) {\n            saveConfig(colIndex, hidden);\n        }\n    }\n});\n

\n\n\n

In both examples above, the ability to apply a CSS class to all cells in a column (including the\nheader) is demonstrated through the use of the id config\noption. This column could be styled by including the following css:

\n\n\n

 //add this css *after* the core css is loaded\n.x-grid3-td-company {\n    color: red; // entire column will have red font\n}\n// modify the header row only, adding an icon to the column header\n.x-grid3-hd-company {\n    background: transparent\n        url(../../resources/images/icons/silk/building.png)\n        no-repeat 3px 3px ! important;\n        padding-left:20px;\n}\n

\n\n\n

Note that the \"Company Name\" column could be specified as the\nExt.grid.GridPanel.autoExpandColumn.

DOM events from ExtJs Components

\n\n\n

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

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

\n\n

// Plugin is configured with a listeners config object.\n// The Component is appended to the argument list of all handler functions.\nExt.DomObserver = Ext.extend(Object, {\n    constructor: function(config) {\n        this.listeners = config.listeners ? config.listeners : config;\n    },\n\n    // Component passes itself into plugin's init method\n    init: function(c) {\n        var p, l = this.listeners;\n        for (p in l) {\n            if (Ext.isFunction(l[p])) {\n                l[p] = this.createHandler(l[p], c);\n            } else {\n                l[p].fn = this.createHandler(l[p].fn, c);\n            }\n        }\n\n        // Add the listeners to the Element immediately following the render call\n        c.render = c.render.createSequence(function() {\n            var e = c.getEl();\n            if (e) {\n                e.on(l);\n            }\n        });\n    },\n\n    createHandler: function(fn, c) {\n        return function(e) {\n            fn.call(this, e, c);\n        };\n    }\n});\n\nvar combo = new Ext.form.ComboBox({\n\n    // Collapse combo when its element is clicked on\n    plugins: [ new Ext.DomObserver({\n        click: function(evt, comp) {\n            comp.collapse();\n        }\n    })],\n    store: myStore,\n    typeAhead: true,\n    mode: 'local',\n    triggerAction: 'all'\n});\n

Parameters

eventName : String

\n
handler : Function
The method the event invokes.
\n
scope : Object (optional)
The scope (this reference) in which the handler function is executed.\nIf omitted, defaults to the object which fired the event.
\n
options : Object (optional)
An object containing handler configuration.\nproperties. This may contain any of the following properties:
- scope : Object
  The scope (this reference) in which the handler function is executed.\nIf omitted, defaults to the object which fired the event.
- delay : Number
  The number of milliseconds to delay the invocation of the handler after the event fires.
- single : Boolean
  True to add a handler to handle just the next firing of the event, and then remove itself.
- buffer : Number
  Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed\nby the specified number of milliseconds. If the event fires again within that time, the original\nhandler 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\nif the event was bubbled up from a child Observable.
\n\n
\nCombining Options
\nUsing the options argument, it is possible to combine different types of listeners:
\n
\nA delayed, one-time listener.\n
```
myDataView.on('click', this.onClick, this, {\nsingle: true,\ndelay: 100\n});
```
\n
\nAttaching multiple handlers in 1 call
\nThe method also allows for a single argument to be passed which is a config object containing properties\nwhich specify multiple handlers.\n
\n
```
myGridPanel.on({\n'click' : {\n    fn: this.onClick,\n    scope: this,\n    delay: 100\n},\n'mouseover' : {\n    fn: this.onMouseOver,\n    scope: this\n},\n'mouseout' : {\n    fn: this.onMouseOut,\n    scope: this\n}\n});

enableBubble( events )

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

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

\n\n\n

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

\n\n\n

Example:

\n\n\n

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