Ext.grid.plugin.EditingExt.grid.plugin.RowEditingMixins
The Ext.grid.plugin.RowEditing plugin injects editing at a row level for a Grid. When editing begins, -a small floating dialog will be shown for the appropriate row. Each editable column will show a field -for editing. There is a button to save or cancel all changes for the edit.
- -The field that will be used for the editor is defined at the -field. The editor can be a field instance or a field configuration. -If an editor is not specified for a particular column then that column won't be editable and the value of -the column will be displayed.
- -The editor may be shared for each column in the grid, or a different one may be specified for each column. -An appropriate field type should be chosen to match the data structure that it will be editing. For example, -to edit a date, it would be useful to specify Ext.form.field.Date as the editor.

- storeId:'simpsonsStore',
- fields:['name', 'email', 'phone'],
- data:{'items':[
- {"name":"Lisa", "email":"lisa@simpsons.com", "phone":"555-111-1224"},

-Ext.create('Ext.grid.Panel', {
- title: 'Simpsons',
- store: Ext.data.StoreManager.lookup('simpsonsStore'),
- columns: [
- {header: 'Name', dataIndex: 'name', field: 'textfield'},

- clicksToEdit: 1
- })
- ],
- height: 200,
- width: 400,
- renderTo: Ext.getBody()
-});
-Config Options
Other Configs
true to automatically cancel any pending changes when the row editor begins editing a new row.
-false to force the user to explicitly cancel the pending changes. Defaults to true.
The number of clicks on a grid required to display the editor (defaults to 2).
-The number of clicks on a grid required to display the editor (defaults to 2).
-The number of clicks to move the row editor to a new row while it is visible and actively editing another row. -This will default to the same value as clicksToEdit.
-true to show a tooltip that summarizes all validation errors present
-in the row editor. Set to false to prevent the tooltip from showing. Defaults to true.
(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 child element of a Component, we need to specify the element option to
-identify the Component property to add a DOM listener to:
new Ext.panel.Panel({
- width: 400,
- height: 200,
- dockedItems: [{
- xtype: 'toolbar'
- }],
- listeners: {
- click: {
- element: 'el', //bind to the underlying el property on the panel
- fn: function(){ console.log('click el'); }
- },
- dblclick: {
- element: 'body', //bind to the underlying body property on the panel
- fn: function(){ console.log('dblclick body'); }
- }
- }
-});
-Methods
Adds the specified events to the list of events which this Observable may fire.
-Adds the specified events to the list of events which this Observable may fire.
-Parameters
- o : Object/String
Either an object with event names as properties with a value of
-true-or the first event name string if multiple event names are being passed as separate parameters. - : String
[additional] Optional additional event names if multiple event names are being passed as separate parameters. -Usage:
- -
- -this.addEvents('storeloaded', 'storecleared'); -
Returns
- void -
Appends an event handler to this object.
-Appends an event handler to this object.
-Parameters
- eventName : String
The name of the event to listen for. May also be an object who's property names are event names. See
- - handler : Function
The method the event invokes.
- - scope : Object
(optional) The scope (
-thisreference) in which the handler function is executed. -If omitted, defaults to the object which fired the event. - options : Object
(optional) An object containing handler configuration. -properties. This may contain any of the following properties:
-
-
- scope : ObjectThe scope (
thisreference) in which the handler function is executed. -If omitted, defaults to the object which fired the event.
- - delay : NumberThe number of milliseconds to delay the invocation of the handler after the event fires.
-
- single : BooleanTrue to add a handler to handle just the next firing of the event, and then remove itself.
-
- buffer : NumberCauses 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 : ObservableOnly call the handler if the event was fired on the target Observable, not -if the event was bubbled up from a child Observable.
-
- element : StringThis option is only valid for listeners bound to Components. -The name of a Component property which references an element to add a listener to. - -
This option is useful during Component construction to add DOM event listeners to elements of Components which -will exist only after the Component is rendered. For example, to add a click listener to a Panel's body: -
- - -new Ext.panel.Panel({ - title: 'The title', - listeners: { - click: this.handlePanelClick, - element: 'body' - } -}); -When added in this way, the options available are the options applicable to Ext.core.Element.addListener
- - -
-
- --Combining Options
-Using the options argument, it is possible to combine different types of listeners:
-
-A delayed, one-time listener. -
-myPanel.on('hide', this.handleClick, 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 events. For example: -
. -myGridPanel.on({ - cellClick: this.onCellClick, - mouseover: this.onMouseOver, - mouseout: this.onMouseOut, - scope: this // Important. Ensure "this" is correct during handler execution -}); -- -

-Returns
- void -
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.Base, {
-// Add functionality to Field's initComponent to enable the change event to bubble
-initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, 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');
- }
-}
-});

The event name to bubble, or an Array of event names.
