How to display a quickinfo in an icon?

Hello,

I currently have a table that contains a column with only icons (print icons). I would like to show a quick info after the user puts the mouse over.

I tried calling the function "ICON_CREATE", but it only shows "xx\" instead of the icon image.
In addition, I tried to do this: icon='@xx \Q quickinfo@', but it doesn't work either.

Thank you so much for the help.
