Ext.layout.container.Fit

This is a base class for layouts that contain a single item that automatically expands to fill the layout's container. This class is intended to be extended or created via the layout:'fit' Ext.Container.layout config, and should generally not need to be created directly via the new keyword.

FitLayout does not have any direct config options (other than inherited ones). To fit a panel to a container using FitLayout, simply set layout:'fit' on the container and add a single panel to it. If the container has multiple panels, only the first one will be displayed. Example usage:

var p = new Ext.Panel({
    title: 'Fit Layout',
    layout:'fit',
    items: {
        title: 'Inner Panel',
        html: '<p>This is the inner panel content</p>',
        border: false
    }
});
