adding icons to xml menu

i have the the documentation under using componenets->menu componenet -> using
the menu component.
i have the menu working fine but i cannot add icon to the items.
this is what i am doing.
myMDP.addMenuItem({label:"Lowerhand", instanceName:"miLowerhand",icon:
"tag"});
tag is a graphic in the library.
i don t know what to do nor have a clue to what are the requirements for the
icon.

please help

ok figured it out

you have to use the linkage properties
so select an item u want to use for the icon right click -> go to linkage
property and give it a name. then use the folllowing syntax

myMenu.addMenuItem({label:"Lowerhand", instanceName:"miLowerhand",name:
"blah",icon:"boot_1"});
