10 * @class Ext.ColorPalette
11 * @extends Ext.Component
12 * Simple color palette class for choosing colors. The palette can be rendered to any container.<br />
13 * Here's an example of typical usage:
15 var cp = new Ext.ColorPalette({value:'993300'}); // initial selected color
18 cp.on('select', function(palette, selColor){
19 // do something with selColor
23 * Create a new ColorPalette
24 * @param {Object} config The config object
27 Ext.ColorPalette = Ext.extend(Ext.Component, {
28 <div id="cfg-Ext.ColorPalette-tpl"></div>/**
29 * @cfg {String} tpl An existing XTemplate instance to be used in place of the default template for rendering the component.
31 <div id="cfg-Ext.ColorPalette-itemCls"></div>/**
32 * @cfg {String} itemCls
33 * The CSS class to apply to the containing element (defaults to 'x-color-palette')
35 itemCls : 'x-color-palette',
36 <div id="cfg-Ext.ColorPalette-value"></div>/**
38 * The initial color to highlight (should be a valid 6-digit color hex code without the # symbol). Note that
39 * the hex codes are case-sensitive.
42 <div id="cfg-Ext.ColorPalette-clickEvent"></div>/**
43 * @cfg {String} clickEvent
44 * The DOM event that will cause a color to be selected. This can be any valid event name (dblclick, contextmenu).
45 * Defaults to <tt>'click'</tt>.
49 ctype : 'Ext.ColorPalette',
51 <div id="cfg-Ext.ColorPalette-allowReselect"></div>/**
52 * @cfg {Boolean} allowReselect If set to true then reselecting a color that is already selected fires the {@link #select} event
54 allowReselect : false,
56 <div id="prop-Ext.ColorPalette-colors"></div>/**
57 * <p>An array of 6-digit color hex code strings (without the # symbol). This array can contain any number
58 * of colors, and each hex code should be unique. The width of the palette is controlled via CSS by adjusting
59 * the width property of the 'x-color-palette' class (or assigning a custom class), so you can balance the number
60 * of colors with the width setting until the box is symmetrical.</p>
61 * <p>You can override individual colors if needed:</p>
63 var cp = new Ext.ColorPalette();
64 cp.colors[0] = 'FF0000'; // change the first box to red
67 Or you can provide a custom array of your own for complete control:
69 var cp = new Ext.ColorPalette();
70 cp.colors = ['000000', '993300', '333300'];
75 '000000', '993300', '333300', '003300', '003366', '000080', '333399', '333333',
76 '800000', 'FF6600', '808000', '008000', '008080', '0000FF', '666699', '808080',
77 'FF0000', 'FF9900', '99CC00', '339966', '33CCCC', '3366FF', '800080', '969696',
78 'FF00FF', 'FFCC00', 'FFFF00', '00FF00', '00FFFF', '00CCFF', '993366', 'C0C0C0',
79 'FF99CC', 'FFCC99', 'FFFF99', 'CCFFCC', 'CCFFFF', '99CCFF', 'CC99FF', 'FFFFFF'
