16 * @class Ext.grid.property.Grid
17 * @extends Ext.grid.Panel
18 * A specialized grid implementation intended to mimic the traditional property grid as typically seen in
19 * development IDEs. Each row in the grid represents a property of some object, and the data is stored
20 * as a set of name/value pairs in {@link Ext.grid.property.Property Properties}. Example usage:
22 var grid = new Ext.grid.property.Grid({
23 title: 'Properties Grid',
27 "(name)": "My Object",
28 "Created": Ext.Date.parse('10/15/2006', 'm/d/Y'),
31 "Description": "A test object"
36 Ext.define('Ext.grid.property.Grid', {
38 extend: 'Ext.grid.Panel',
40 alias: 'widget.propertygrid',
42 alternateClassName: 'Ext.grid.PropertyGrid',
45 'Ext.grid.plugin.CellEditing',
46 'Ext.grid.property.Store',
47 'Ext.grid.property.HeaderContainer',
49 'Ext.grid.CellEditor',
50 'Ext.form.field.Date',
51 'Ext.form.field.Text',
52 'Ext.form.field.Number'
56 * @cfg {Object} propertyNames An object containing custom property name/display name pairs.
57 * If specified, the display name will be shown in the name column instead of the property name.
61 * @cfg {Object} source A data object to use as the data source of the grid (see {@link #setSource} for details).
65 * @cfg {Object} customEditors An object containing name/value pairs of custom editor type definitions that allow
66 * the grid to support additional types of editable fields. By default, the grid supports strongly-typed editing
67 * of strings, dates, numbers and booleans using built-in form editors, but any custom type can be supported and
68 * associated with a custom input control by specifying a custom editor. The name of the editor
69 * type should correspond with the name of the property that will use the editor. Example usage:
71 var grid = new Ext.grid.property.Grid({
73 // Custom editors for certain property names
75 evtStart: Ext.create('Ext.form.TimeField' {selectOnFocus:true})
78 // Displayed name for property names in the source
80 evtStart: 'Start Time'
83 // Data object containing properties to edit
92 * @cfg {Object} source A data object to use as the data source of the grid (see {@link #setSource} for details).
96 * @cfg {Object} customRenderers An object containing name/value pairs of custom renderer type definitions that allow
97 * the grid to support custom rendering of fields. By default, the grid supports strongly-typed rendering
98 * of strings, dates, numbers and booleans using built-in form editors, but any custom type can be supported and
99 * associated with the type of the value. The name of the renderer type should correspond with the name of the property
100 * that it will render. Example usage:
102 var grid = Ext.create('Ext.grid.property.Grid', {
104 Available: function(v){
106 return '<span style="color: green;">Yes</span>';
108 return '<span style="color: red;">No</span>';
120 * @cfg {String} valueField
121 * Optional. The name of the field from the property store to use as the value field name. Defaults to <code>'value'</code>
122 * This may be useful if you do not configure the property Grid from an object, but use your own store configuration.
127 * @cfg {String} nameField
128 * Optional. The name of the field from the property store to use as the property field name. Defaults to <code>'name'</code>
129 * This may be useful if you do not configure the property Grid from an object, but use your own store configuration.
134 * @cfg {Number} nameColumnWidth
135 * Optional. Specify the width for the name column. The value column will take any remaining space. Defaults to <tt>115</tt>.
