Class Ext.ux.layout.CenterLayout

This is a very simple layout style used to center contents within a container. This layout works within nested containers and can also be used as expected as a Viewport layout to center the page layout.

As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses the layout. The layout does not require any config options, although the child panel contained within the layout must provide a fixed or percentage width. The child panel's height will fit to the container by default, but you can specify autoHeight:true to allow it to autosize based on its content height. Example usage:

// The content panel is centered in the container
var p = new Ext.Panel({
    title: 'Center Layout',
    layout: 'ux.center',
    items: [{
        title: 'Centered Content',
        width: '75%',
        html: 'Some content'
    }]
});

// If you leave the title blank and specify no border
// you'll create a non-visual, structural panel just
// for centering the contents in the main container.
var p = new Ext.Panel({
    layout: 'ux.center',
    border: false,
    items: [{
        title: 'Centered Content',
        width: 300,
        autoHeight: true,
        html: 'Some content'
    }]
});
