Hi All,

Is it possible to have keyPressed() in J2ME List? Is commandAction() is
the only Listener method?

No. keyPressed() is a method of javax.microedition.lcdui.Canvas.
javax.microedition.lcdui.List does *not* extend Canvas in the
specification, so how could it provide Canvas's methods?

commandAction is the only method invoked by a Displayable object when a
Command has been fired, yes.

Thanks for the reply.... My problem is that when the user presses the
Last item of the List and still presses the down arrow, the first item
has to be selected? I s there any solution?

This behavior is up to the device, only way I can think of is mimicking
a list on a Canvas, but whether that's worth the effort ?

Not really, no. Why is circumnavigating the list a problem?
