/** * The VBox (short for vertical box) layout makes it easy to position items horizontally in a * {@link Ext.Container Container}. It can size items based on a fixed height or a fraction of the total height * available. * * For example, let's say we want a banner to take one third of the available height, and an information panel in the * rest of the screen. We can achieve this with vbox layout's *flex* config: * * @example * Ext.create('Ext.Container', { * fullscreen: true, * layout: 'vbox', * items: [ * { * html: 'Awesome banner', * style: 'background-color: #759E60;', * flex: 1 * }, * { * html: 'Some wonderful information', * style: 'background-color: #5E99CC;', * flex: 2 * } * ] * }); * * This will give us two boxes - one that's one third of the available height, the other being two thirds of the * available height. * * We can also specify fixed heights for child items, or mix fixed heights and flexes. For example, here we have 3 * items - one at the top and bottom with flex: 1, and one in the center with a fixed width of 100px: * * @example preview portrait * Ext.create('Ext.Container', { * fullscreen: true, * layout: 'vbox', * items: [ * { * html: 'Top item', * style: 'background-color: #5E99CC;', * flex: 1 * }, * { * html: 'Center item', * height: 100 * }, * { * html: 'Bottom item', * style: 'background-color: #759E60;', * flex: 1 * } * ] * }); */Ext.define('Ext.layout.VBox', { extend: 'Ext.layout.FlexBox', alias: 'layout.vbox', config: { orient: 'vertical' }});
