Name
CommandListener
Synopsis
An interface implemented by objects that want to be notified when the user activates
a Command
associated with a Displayable
. A
Displayable
can have a single CommandListener
,
set using its setCommandListener()
method.
When any Command
on a Displayable
is activated, its CommandListener
’s
commandAction()
method is called. In order to allow a single
listener to handle the actions associated with more than one Command
,
this method receives a reference to both the Command
itself
and the Displayable
that this instance of the
Command
is associated with. The commandAction()
method is typically invoked in the context of the thread that is responsible for managing
the user interface and therefore any delay caused by this method may cause the user interface
to appear to be unresponsive.
public interface CommandListener { // Public Instance Methods public abstract void commandAction(Command c, Displayable d); }
