PLZ HELP - put a canvas as a background on a form

i read in this thread http://forum.java.sun.com/thread.jspa?threadID=5170550 that i could put a canvas as a background on a form with regular midp2.0, i searched the forums but i can figure out how to do this. my goal is to catch keypresses from an implicit list, is it possible to put a canvas in the background of a list instead? it would be greatly appreciated if someone could point me in the right direction. thanks.
