ActionListener. The following methods are also available:
public void addNotify()
public String getLabel()
public synchronized void setLabel(String label)
public void setActionCommand(String command)
public String getActionCommand()
public void addActionListener(ActionListener l)
public void removeActionListener(ActionListener l)
addNotify() creates the Button's peer object, that is
the native widget that has the appearance of a Windows button
or a Mac button or a Motif button or whatever. It is extremely rare
to call this directly.
The getLabel() and setLabel(String s) methods allow you to retrieve and change the text of the button while the applet is running. Given a Button b, here is how they might be used
String s = b.getLabel();
b.setLabel("Here's the new label");
getLabel()
returns a String, not a Label.
The setActionCommand() and
getActionCommand() methods modify the command
string sent along with the ActionEvent. By default
this is the label of the button, but it can be changed. For
instance, you could use this as a way to pass the number of
times the BeepApplet should beep
Finally addActionListener() registers another
object as one which should receive ActionEvents
fired by the Button.
removeActionListener() deregisters the
ActionListener object l so it will no
longer receive action events fired by this Button.
