Loading icon in bubble-panel in chameleon theme

Hi,
Does somebody know how to add the
icon
in the
Bubble panel
of
chameleon theme
?

The problem is that the panels view of the chameleon
demo
(http://demo.vaadin.com/chameleontheme) doesn’t shows the tooltips needed to apply the correspondent css styles.

thanks

Sorry my ignorance, I am picking information from here and there…

as everybody should know icons are incorporated with:

somecomponent.setIcon(new ThemeResource(“place_of_icon”));
