I\'m Using FontAwesome with ExtJS in my app.
All other buttons are working fine with font awesome when I do this:
iconCls: \'fa fa-edit\' >
iconCls: \'fa fa-edit\'
Looks like the overrides don't work if you are in 4.0 - 4.1. I went the path of least resistance and just made the icons into png format via http://fa2png.io/ then defined the assigned class to a background-image url in the css.
