Constructor Index

o MVCTextField()
Default constructor

Method Index

o action(Event, Object)
When the action occurs (the user accepts the value shown), then make sure to update the model.
o converter()
Return the current print converter we are using, or null if we aren't using ones (just dealing with strings).
o converter(PrintConverter)
Sets the current print converter to, or null if we just want to deal with strings.
o converter(ObjectPrinter)
If this will be used as a read-only field, then you can use an ObjectPrinter instead of a PrintConverter.
o getModel()
Retrieve the model, lazy initialize one if necessary.
o getValue()
Return the appropriate object which the current widget contents represent.
o lostFocus(Event, Object)
It would be great if this actually worked, but at least in Win32 I never get this event.
o removeNotify()
Before we die, remove dependency on model.
o setModel(ValueModel)
Give the widget a new model.
o setType(int)
Set the type of the text field.
o update(Observable, Object)
Called when observers in the observable list need to be updated.

Constructors

o MVCTextField 
  public MVCTextField()
Default constructor
o MVCTextField 
  public MVCTextField(int cols)
Constructs a new TextField initialized with the specified columns.
Parameters:
cols - the number of columns

Methods

o getModel 
  public synchronized ValueModel getModel()
Retrieve the model, lazy initialize one if necessary.
Returns:
the model the widget is using
o getValue 
  protected Object getValue()
Return the appropriate object which the current widget contents represent. In general, consumers should use ValueModel#getValue on my model.
Returns:
the object representing the value
o setModel 
  public synchronized void setModel(ValueModel newModel)
Give the widget a new model. This will also update the contents of the field.
Parameters:
newModel - the new model for the widget
o converter 
  public PrintConverter converter()
Return the current print converter we are using, or null if we aren't using ones (just dealing with strings).
Returns:
the current print converter in use
o converter 
  public void converter(PrintConverter newConverter)
Sets the current print converter to, or null if we just want to deal with strings.
Parameters:
newConverter - the new converter to use
o converter 
  public void converter(ObjectPrinter aPrinter)
If this will be used as a read-only field, then you can use an ObjectPrinter instead of a PrintConverter. An exception will be thrown if you attempt to read from the text field.
o update 
  public void update(Observable o,
                     Object arg)
Called when observers in the observable list need to be updated.
Parameters:
o - the observer sending the update
arg - the new value
o action 
  public boolean action(Event event,
                        Object what)
When the action occurs (the user accepts the value shown), then make sure to update the model.
Returns:
whether the event was handled
Overrides:
action in class Component
o lostFocus 
  public boolean lostFocus(Event event,
                           Object what)
It would be great if this actually worked, but at least in Win32 I never get this event. Bummer.
Returns:
whether the event was handled
Overrides:
lostFocus in class Component
o setType 
  public void setType(int newType)
Set the type of the text field. Right now, this is a "write only" value, because we don't hold onto the state.
Parameters:
newType - an int representing the type
o removeNotify 
  public synchronized void removeNotify()
Before we die, remove dependency on model.
Overrides:
removeNotify in class TextComponent
