    Default Ext.ux.util.AlwaysOnTop

    Ext.ux.util.AlwaysOnTop


    Always On Top extension for Ext JS 4.x

    I have created a 4.x controller adding alwaysOnTop feature to floating components.

    NOTE: I changed the name of the extension to Ext.ux.util.AlwaysOnTop to match the changes from version 1.0 to 1.1.

    The controller is quite simple and works by assigning a separate z-index manager for all floating components that have the property alwaysOnTop set to true.

    Demos and instructions can be found on this page:
    http://www.eirik.net/Ext/ux/util/AlwaysOnTop.html

    Or simply paste this code into a AlwaysOnTop.js file:
