- a list of Menu Items: a popup Menu will be created that will

- `icon`: the name of an icon to be displayed with the item text.
This name should be that of one of the icons in the pyFormex

- `shortcut`: is an optional key combination to select the item.
- `tooltip`: a text that is displayed as popup help.
