/** * The HBox (short for horizontal box) layout makes it easy to position items horizontally in a * {@link Ext.Container Container}. It can size items based on a fixed width or a fraction of the total width * available. * * For example, an email client might have a list of messages pinned to the left, taking say one third of the available * width, and a message viewing panel in the rest of the screen. We can achieve this with hbox layout's *flex* config: * * @example * Ext.create('Ext.Container', { * fullscreen: true, * layout: 'hbox', * items: [ * { * html: 'message list', * style: 'background-color: #5E99CC;', * flex: 1 * }, * { * html: 'message preview', * style: 'background-color: #759E60;', * flex: 2 * } * ] * }); * * This will give us two boxes - one that's one third of the available width, the other being two thirds of the * available width. * * We can also specify fixed widths for child items, or mix fixed widths and flexes. For example, here we have 3 items * - one on each side with flex: 1, and one in the center with a fixed width of 100px: * * @example * Ext.create('Ext.Container', { * fullscreen: true, * layout: 'hbox', * items: [ * { * html: 'Left item', * style: 'background-color: #759E60;', * flex: 1 * }, * { * html: 'Center item', * width: 100 * }, * { * html: 'Right item', * style: 'background-color: #5E99CC;', * flex: 1 * } * ] * }); */Ext.define('Ext.layout.HBox', { extend: 'Ext.layout.Box', alias: 'layout.hbox', config: { vertical: false }});
