/** * @class Ext.ColorPalette * @extends Ext.Component * Simple color palette class for choosing colors. The palette can be rendered to any container.
* Here's an example of typical usage: *

var cp = new Ext.ColorPalette({value:'993300'});  // initial selected color
cp.render('my-div');

cp.on('select', function(palette, selColor){
    // do something with selColor
});
* @constructor * Create a new ColorPalette * @param {Object} config The config object * @xtype colorpalette */ Ext.ColorPalette = Ext.extend(Ext.Component, {
/** * @cfg {String} tpl An existing XTemplate instance to be used in place of the default template for rendering the component. */
/** * @cfg {String} itemCls * The CSS class to apply to the containing element (defaults to 'x-color-palette') */ itemCls : 'x-color-palette',
/** * @cfg {String} value * The initial color to highlight (should be a valid 6-digit color hex code without the # symbol). Note that * the hex codes are case-sensitive. */ value : null,
/** * @cfg {String} clickEvent * The DOM event that will cause a color to be selected. This can be any valid event name (dblclick, contextmenu). * Defaults to 'click'. */ clickEvent :'click', // private ctype : 'Ext.ColorPalette',
/** * @cfg {Boolean} allowReselect If set to true then reselecting a color that is already selected fires the {@link #select} event */ allowReselect : false,
/** *

An array of 6-digit color hex code strings (without the # symbol). This array can contain any number * of colors, and each hex code should be unique. The width of the palette is controlled via CSS by adjusting * the width property of the 'x-color-palette' class (or assigning a custom class), so you can balance the number * of colors with the width setting until the box is symmetrical.

*

You can override individual colors if needed:

*

var cp = new Ext.ColorPalette();
cp.colors[0] = 'FF0000';  // change the first box to red
Or you can provide a custom array of your own for complete control:

var cp = new Ext.ColorPalette();
cp.colors = ['000000', '993300', '333300'];
* @type Array */ colors : [ '000000', '993300', '333300', '003300', '003366', '000080', '333399', '333333', '800000', 'FF6600', '808000', '008000', '008080', '0000FF', '666699', '808080', 'FF0000', 'FF9900', '99CC00', '339966', '33CCCC', '3366FF', '800080', '969696', 'FF00FF', 'FFCC00', 'FFFF00', '00FF00', '00FFFF', '00CCFF', '993366', 'C0C0C0', 'FF99CC', 'FFCC99', 'FFFF99', 'CCFFCC', 'CCFFFF', '99CCFF', 'CC99FF', 'FFFFFF' ],
