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 onRender : function(container, position){
93 var t = this.tpl || new Ext.XTemplate(
94 '<tpl for="."><a href="#" class="color-{.}" hidefocus="on"><em><span style="background:#{.}" unselectable="on"> </span></em></a></tpl>'
96 var el = document.createElement("div");
98 el.className = this.itemCls;
99 t.overwrite(el, this.colors);
100 container.dom.insertBefore(el, position);
101 this.el = Ext.get(el);
102 this.mon(this.el, this.clickEvent, this.handleClick, this, {delegate: 'a'});

104 this.mon(this.el, 'click', Ext.emptyFn, this, {delegate: 'a', preventDefault: true});

119 handleClick : function(e, t){
122 var c = t.className.match(/(?:^|\s)color-(.{6})(?:\s|$)/)[1];
123 this.select(c.toUpperCase());
128 * Selects the specified color in the palette (fires the {@link #select} event)
129 * @param {String} color A valid 6-digit color hex code (# will be stripped if included)
