16 * @class Ext.ColorPalette
17 * @extends Ext.Component
18 * Simple color palette class for choosing colors. The palette can be rendered to any container.<br />
19 * Here's an example of typical usage:
21 var cp = new Ext.ColorPalette({value:'993300'}); // initial selected color
24 cp.on('select', function(palette, selColor){
25 // do something with selColor
29 * Create a new ColorPalette
30 * @param {Object} config The config object
33 Ext.ColorPalette = Ext.extend(Ext.Component, {
34 <div id="cfg-Ext.ColorPalette-tpl"></div>/**
35 * @cfg {String} tpl An existing XTemplate instance to be used in place of the default template for rendering the component.
37 <div id="cfg-Ext.ColorPalette-itemCls"></div>/**
38 * @cfg {String} itemCls
39 * The CSS class to apply to the containing element (defaults to 'x-color-palette')
41 itemCls : 'x-color-palette',
42 <div id="cfg-Ext.ColorPalette-value"></div>/**
44 * The initial color to highlight (should be a valid 6-digit color hex code without the # symbol). Note that
45 * the hex codes are case-sensitive.
48 <div id="cfg-Ext.ColorPalette-clickEvent"></div>/**
49 * @cfg {String} clickEvent
50 * The DOM event that will cause a color to be selected. This can be any valid event name (dblclick, contextmenu).
51 * Defaults to <tt>'click'</tt>.
55 ctype : 'Ext.ColorPalette',
57 <div id="cfg-Ext.ColorPalette-allowReselect"></div>/**
58 * @cfg {Boolean} allowReselect If set to true then reselecting a color that is already selected fires the {@link #select} event
60 allowReselect : false,
62 <div id="prop-Ext.ColorPalette-colors"></div>/**
63 * <p>An array of 6-digit color hex code strings (without the # symbol). This array can contain any number
64 * of colors, and each hex code should be unique. The width of the palette is controlled via CSS by adjusting
65 * the width property of the 'x-color-palette' class (or assigning a custom class), so you can balance the number
66 * of colors with the width setting until the box is symmetrical.</p>
67 * <p>You can override individual colors if needed:</p>
69 var cp = new Ext.ColorPalette();
70 cp.colors[0] = 'FF0000'; // change the first box to red
73 Or you can provide a custom array of your own for complete control:
75 var cp = new Ext.ColorPalette();
76 cp.colors = ['000000', '993300', '333300'];
81 '000000', '993300', '333300', '003300', '003366', '000080', '333399', '333333',
82 '800000', 'FF6600', '808000', '008000', '008080', '0000FF', '666699', '808080',
83 'FF0000', 'FF9900', '99CC00', '339966', '33CCCC', '3366FF', '800080', '969696',
84 'FF00FF', 'FFCC00', 'FFFF00', '00FF00', '00FFFF', '00CCFF', '993366', 'C0C0C0',
