lcdui.list — Creates a full-screen list
lcdui.list
[-title title]
[-type
exclusive
| multiple
| implicit
]
[-selectcommand cmd]
The lcdui.list command creates a full-screen list and returns a command/object that can be used to manipulate it. For an in-depth look at the Java code that this command is based on, see: javax.microedition.lcdui.List
The options unique to this command are as follows:
-type: One of exclusive,
multiple or implicit. Exclusive and multiple
correspond, respectively, to radio buttons and checkboxes. Implicit lists act like
a menu, dispatching to the list's -commandaction when a list item
is selected.
-selectcommand: Select the command which should be used for
implicit list select actions.
