A NumberField is basically a JPanel holding a JTextField whose content is limited to decimal numbers. The idea is somewhat similar to FScape's ParamField, but we try to avoid the conceptual drawbacks made there.

Number formatting is accomplished by using a NumberFormat object whose configuration is determinated by a NumberSpace given to the constructor.

Clients can listen to user edits by registering a NumberListener.

Constructor Detail

NumberField

public NumberField()
Create a new NumberField for a given space. the initial value of the NumberField is taken from space.reset. The number of displayed integers and decimals is calculated by evaluating the space's min, max and quant fields. If the quant field is integer, no decimals are displayed. User adjustments of the number are automatically trimmed to the space's min and max and quantisized to its quant field


NumberField

public NumberField(NumberSpace space)
Method Detail

setSpace

public void setSpace(NumberSpace space)

setFlags

public void setFlags(int newFlags)

getFlags

public int getFlags()

getNumber

public java.lang.Number getNumber()
Return the number currently displayed

Returns:
the number displayed in the gadget. if the NumberSpace is integer, a Long is returned, otherwise a Double.
See Also:
NumberSpace.isInteger()
Warning:
if the number was set using the setNumber method, it is possible that the returned object is neither Long nor Double. Thus never cast it to a subclass of Number, but rather use an appropriate translation like intValue() or doubleValue()!

setNumber

public void setNumber(java.lang.Number value)
Set the gadget contents to a new number. No event is fired. Though the number is formatted according to the space's settings (e.g. number of decimals), its value is not altered, even if it exceeds the space's bounds.

Parameters:
value - the new number to display

getSpace

public NumberSpace getSpace()
Returns the used number space.

Returns:
the NumberSpace that was used to construct the NumberField.

addListener

public void addListener(NumberListener listener)
Register a NumberListener which will be informed about changes of the gadgets content.

Parameters:
listener - the NumberListener to register
See Also:
EventManager.addListener( Object )

removeListener

public void removeListener(NumberListener listener)
Unregister a NumberListener from receiving number change events.

Parameters:
listener - the NumberListener to unregister
See Also:
EventManager.removeListener( Object )

processEvent

public void processEvent(BasicEvent e)
Description copied from interface: EventManager.Processor
Processes the next event in the queue. This gets called in the event thread. Usually implementing classes should loop through all listeners by calling elm.countListeners() and elm.getListener(), and invoke specific dispatching methods on these listeners.

Specified by:
processEvent in interface EventManager.Processor

fireNumberChanged

protected void fireNumberChanged()
