8 * @class Ext.ColorPalette
9 * @extends Ext.Component
10 * Simple color palette class for choosing colors. The palette can be rendered to any container.<br />
11 * Here's an example of typical usage:
13 var cp = new Ext.ColorPalette({value:'993300'}); // initial selected color
16 cp.on('select', function(palette, selColor){
17 // do something with selColor
21 * Create a new ColorPalette
22 * @param {Object} config The config object
25 Ext.ColorPalette = function(config){
26 Ext.ColorPalette.superclass.constructor.call(this, config);
30 * Fires when a color is selected
31 * @param {ColorPalette} this
32 * @param {String} color The 6-digit color hex code (without the # symbol)
38 this.on('select', this.handler, this.scope, true);
41 Ext.extend(Ext.ColorPalette, Ext.Component, {
43 * @cfg {String} tpl An existing XTemplate instance to be used in place of the default template for rendering the component.
46 * @cfg {String} itemCls
47 * The CSS class to apply to the containing element (defaults to 'x-color-palette')
49 itemCls : 'x-color-palette',
52 * The initial color to highlight (should be a valid 6-digit color hex code without the # symbol). Note that
53 * the hex codes are case-sensitive.
58 ctype : 'Ext.ColorPalette',
61 * @cfg {Boolean} allowReselect If set to true then reselecting a color that is already selected fires the {@link #select} event
63 allowReselect : false,
66 * <p>An array of 6-digit color hex code strings (without the # symbol). This array can contain any number
67 * of colors, and each hex code should be unique. The width of the palette is controlled via CSS by adjusting
68 * the width property of the 'x-color-palette' class (or assigning a custom class), so you can balance the number
69 * of colors with the width setting until the box is symmetrical.</p>
70 * <p>You can override individual colors if needed:</p>
72 var cp = new Ext.ColorPalette();
73 cp.colors[0] = 'FF0000'; // change the first box to red
76 Or you can provide a custom array of your own for complete control:
78 var cp = new Ext.ColorPalette();
79 cp.colors = ['000000', '993300', '333300'];
84 '000000', '993300', '333300', '003300', '003366', '000080', '333399', '333333',
85 '800000', 'FF6600', '808000', '008000', '008080', '0000FF', '666699', '808080',
86 'FF0000', 'FF9900', '99CC00', '339966', '33CCCC', '3366FF', '800080', '969696',
87 'FF00FF', 'FFCC00', 'FFFF00', '00FF00', '00FFFF', '00CCFF', '993366', 'C0C0C0',
88 'FF99CC', 'FFCC99', 'FFFF99', 'CCFFCC', 'CCFFFF', '99CCFF', 'CC99FF', 'FFFFFF'
92 * @cfg {Function} handler
93 * Optional. A function that will handle the select event of this palette.
94 * The handler is passed the following parameters:<div class="mdetail-params"><ul>
95 * <li><code>palette</code> : ColorPalette<div class="sub-desc">The {@link #palette Ext.ColorPalette}.</div></li>
96 * <li><code>color</code> : String<div class="sub-desc">The 6-digit color hex code (without the # symbol).</div></li>
100 * @cfg {Object} scope
101 * The scope (<tt><b>this</b></tt> reference) in which the <code>{@link #handler}</code>
102 * function will be called. Defaults to this ColorPalette instance.
