public class PrefNumberField
extends NumberField
implements DynamicListening, java.util.prefs.PreferenceChangeListener, LaterInvocationManager.Listener, PreferenceEntrySync

Equips a NumberField with preference storing / recalling capabilities. We decided not to override setNumber(). Thus, there are two ways to alter the gadget state, either by invoking the setNumberAndDispatch() method (DON'T USE setNumber() because it doesn't fire events) or by changing the associated preferences. When a preference change occurs, the setNumberAndDispatch() method is called, allowing clients to add NumberListeners to the gadget in case they don't want to deal with preferences. However, when possible it is recommended to use PreferenceChangeListener mechanisms.

Field Detail

writePrefs

protected boolean writePrefs

Constructor Detail

PrefNumberField

public PrefNumberField()

Constructs a new PrefNumberField.

Synchronization:

Like any other Swing component, the constructor is to be called from the event thread.

Method Detail

setReadPrefs

public void setReadPrefs(boolean b)

Specified by:

setReadPrefs in interface PreferenceEntrySync

getReadPrefs

public boolean getReadPrefs()

Specified by:

getReadPrefs in interface PreferenceEntrySync

setWritePrefs

public void setWritePrefs(boolean b)

Specified by:

setWritePrefs in interface PreferenceEntrySync

getWritePrefs

public boolean getWritePrefs()

Specified by:

getWritePrefs in interface PreferenceEntrySync

writePrefs

public void writePrefs()

Specified by:

writePrefs in interface PreferenceEntrySync

setPreferenceNode

public void setPreferenceNode(java.util.prefs.Preferences prefs)

Specified by:

setPreferenceNode in interface PreferenceEntrySync

setPreferenceKey

public void setPreferenceKey(java.lang.String key)

Specified by:

setPreferenceKey in interface PreferenceEntrySync

setPreferences

public void setPreferences(java.util.prefs.Preferences prefs,
                           java.lang.String key)

Enable Preferences synchronization. This method is not thread safe and must be called from the event thread. When a preference change is received, the number is updated in the GUI and the NumberField dispatches a NumberEvent. Likewise, if the user adjusts the number in the GUI, the preference will be updated. The same is true, if you call setNumber.

Specified by:

setPreferences in interface PreferenceEntrySync

Parameters:

prefs - the preferences node in which the value is stored, or null to disable prefs sync.

key - the key used to store and recall prefs. the value is the number converted to a string.
