StatusBar Examples
Here are several examples of using and customizing the Ext.ux.StatusBar component.
Note that the js is not minified so it is readable. See statusbar-demo.js.
Basic StatusBar
This is a simple StatusBar with a few standard Toolbar items included.
This is a simple StatusBar that has the status element right-aligned. Any StatusBar items will be added in
exactly the same order on the left side of the bar.
You can add a StatusBar to a window in exactly the same way.
This is a standard StatusBar with some custom CSS styles applied and some event handling in place to
handle the TextArea's keypress events. Notice that after you've stopped typing for a few seconds a
simulated auto-save process will begin.
