How to use a jquery icon in a button

[Alberto]

May be Bruce did not follow my last post so I resume it here.
Trying to use a jQuery icon in a button, as Bruce does in Insert, Change, etc buttons using:

CSS= 'ui-icon ui-icon-calculator'
or
CSS= 'ui-icon-calculator'

The result is what you see in the attached images, you can see that it even change between themes.

Any easy way of use this icons?

Thanks

you just set the template setting, as in the attached pic.
Use the jQuery name, minus the ui- part.
So for the ui-check icon just use
'check'

Cheers
