Ext.AbstractPanel

Panel is a container that has specific functionality and structural components that make it the perfect building block for application-oriented user interfaces.

Panels are, by virtue of their inheritance from Ext.Container, capable of being configured with a layout, and containing child Components.

When either specifying child items of a Panel, or dynamically adding Components to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether those child elements need to be sized using one of Ext's built-in layout schemes. By default, Panels use the ContainerLayout scheme. This simply renders child components, appending them one after the other inside the Container, and does not apply any sizing at all.

A Panel may also contain bottom and top toolbars, along with separate header, footer and body sections (see frame for additional information).

Panel also provides built-in expandable and collapsible behavior, along with a variety of prebuilt tool buttons that can be wired up to provide other customized behavior. Panels can be easily dropped into any Container or layout, and the layout and rendering pipeline is completely managed by the framework.

Note: By default, the close header tool destroys the Window resulting in destruction of any child Components. This makes the Window object, and all its descendants unusable. To enable re-use of a Window, use closeAction: 'hide'.

var panel = new Ext.Panel({
    fullscreen: true,
    dockedItems: [{
        xtype: 'toolbar',
        dock: 'top',
        items: [{
            text: 'Docked to the bottom'
        }]
    }]
});
