/** * @class Ext.dataview.IndexBar * @extend Ext.Component * @xtype indexbar * * IndexBar is a component used to display a list of data (primarily an alphabet) which can then be used to quickly * navigate through a list (see {@link Ext.List}) of data. When a user taps on an item in the {@link Ext.IndexBar}, * it will fire the {@link #index} event. * * Here is an example of the usage in a {@link Ext.List}: * * @example packages=[reactor] * import React, { Component } from 'react' * import { ExtReact, List } from '@sencha/ext-react'; * * export default class MyExample extends Component { * * store = new Ext.data.Store({ * data: [{ * firstName: 'Screech', * lastName: 'Powers' * }, * { * firstName: 'Kelly', * lastName: 'Kapowski' * }, * { * firstName: 'Zach', * lastName: 'Morris' * }, * { * firstName: 'Jessie', * lastName: 'Spano' * }, * { * firstName: 'Lisa', * lastName: 'Turtle' * }, * { * firstName: 'A.C.', * lastName: 'Slater' * }, * { * firstName: 'Richard', * lastName: 'Belding' * }] * }); * * render() { * return ( * <ExtReact> * <List * itemTpl="<div class='contact'>{firstName} <strong>{lastName}</strong></div>" * store={this.store} * indexBar * /> * </ExtReact> * ) * } * } */ /** * @cfg {vertical/horizontal} [direction='vertical] * Layout direction, can be either 'vertical' or 'horizontal' * @accessor */ /** * @event index * Fires when an item in the index bar display has been tapped. * @param {Ext.dataview.IndexBar} this The IndexBar instance * @param {String} html The HTML inside the tapped node. * @param {Ext.dom.Element} target The node on the indexbar that has been tapped. */ /** * @cfg {Array} [letters=['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']] * The letters to show on the index bar. * @accessor */ /** * @cfg {String} [listPrefix=null] * The prefix string to be used at the beginning of the list. * E.g: useful to add a "#" prefix before numbers. * @accessor */
