Methods

publicsynchronized void addPropertyChangeListener (PropertyChangeListener listener) [Specified in Action]

Adds a PropertyChangeListener to the listener list.

Adds a PropertyChangeListener to the listener list. The listener is registered for all properties.

A PropertyChangeEvent will get fired in response to setting a bound property, e.g. setFont, setBackground, or setForeground. Note that if the current component is inheriting its foreground, background, or font from its container, then no event will be fired in response to a change in the inherited property.
Parameters:
- listener - The PropertyChangeListener to be added
See Also: Action.addPropertyChangeListener(java.beans.PropertyChangeListener),

protected Object clone () throws CloneNotSupportedException

Clones the abstract action.

Clones the abstract action. This gives the clone
its own copy of the key/value list,
which is not handled for you by Object.clone().

protected void firePropertyChange (String propertyName, Object oldValue, Object newValue)

Supports reporting bound property changes.

Supports reporting bound property changes. This method can be called
when a bound property has changed and it will send the appropriate
PropertyChangeEvent to any registered
PropertyChangeListeners.

public Object getKeys ()

Returns an array of Objects which are keys for which values have been set for this AbstractAction, or null if no keys have values set.

Returns an array of Objects which are keys for
which values have been set for this AbstractAction,
or null if no keys have values set.
Returns: an array of key objects, or null if no keys have values set
Since: 1.3

publicsynchronized PropertyChangeListener getPropertyChangeListeners ()

Returns an array of all the PropertyChangeListeners added to this AbstractAction with addPropertyChangeListener().

Returns an array of all the PropertyChangeListeners added
to this AbstractAction with addPropertyChangeListener().
Returns: all of the PropertyChangeListeners added or an empty array if no listeners have been added
Since: 1.4

public Object getValue (String key) [Specified in Action]

Gets the Object associated with the specified key.

Gets the Object associated with the specified key.
Returns: the binding Object stored with this key; if there are no keys, it will return null
Parameters:
- key - a string containing the specified key
See Also: Action.getValue(java.lang.String),

pack-privatestatic boolean hasSelectedKey (Action a)

public boolean isEnabled () [Specified in Action]

Returns true if the action is enabled.

pack-privatestatic boolean isSelected (Action a)

public void putValue (String key, Object newValue) [Specified in Action]

Sets the Value associated with the specified key.

Sets the Value associated with the specified key.
Parameters:
- key - the String that identifies the stored object
- newValue - the Object to store using this key
See Also: Action.putValue(java.lang.String, java.lang.Object),

publicsynchronized void removePropertyChangeListener (PropertyChangeListener listener) [Specified in Action]

Removes a PropertyChangeListener from the listener list.

Removes a PropertyChangeListener from the listener list.
This removes a PropertyChangeListener that was registered
for all properties.
Parameters:
- listener - the PropertyChangeListener to be removed
See Also: Action.removePropertyChangeListener(java.beans.PropertyChangeListener),

public void setEnabled (boolean newValue) [Specified in Action]

Enables or disables the action.

pack-privatestatic void setEnabledFromAction (JComponent c, Action a)

Sets the enabled state of a component from an Action.

pack-privatestatic void setToolTipTextFromAction (JComponent c, Action a)

Sets the tooltip text of a component from an Action.

pack-privatestatic boolean shouldReconfigure (PropertyChangeEvent e)

Whether or not to reconfigure all action properties from the specified event.

Fields

Hide/Show inherited fields

publicfinalstatic String ACCELERATOR_KEY = "AcceleratorKey" [Inherited From Action]

The key used for storing a KeyStroke to be used as the accelerator for the action.

The key used for storing a KeyStroke to be used as the
accelerator for the action.
Since: 1.3

publicfinalstatic String ACTION_COMMAND_KEY = "ActionCommandKey" [Inherited From Action]

The key used to determine the command String for the ActionEvent that will be created when an Action is going to be notified as the result of residing in a Keymap associated with a JComponent.

protected SwingPropertyChangeSupport changeSupport

If any PropertyChangeListeners have been registered, the changeSupport field describes them.

publicfinalstatic String DEFAULT = "Default" [Inherited From Action]

Not currently used.

publicfinalstatic String DISPLAYED_MNEMONIC_INDEX_KEY = "SwingDisplayedMnemonicIndexKey" [Inherited From Action]

The key used for storing an Integer that corresponds to the index in the text (identified by the NAME property) that the decoration for a mnemonic should be rendered at.

The key used for storing an Integer that corresponds to the index in the text (identified by the NAME property) that the decoration for a mnemonic should be rendered at. If the value of this property is greater than or equal to the length of the text, it will treated as -1.

Note: the value of this field is prefixed with 'Swing' to avoid possible collisions with existing Actions.
Since: 1.6
See Also: AbstractButton.setDisplayedMnemonicIndex(int),

protected boolean enabled

Specifies whether action is enabled; the default is true.

publicfinalstatic String LARGE_ICON_KEY = "SwingLargeIconKey" [Inherited From Action]

The key used for storing an Icon.

The key used for storing an Icon. This is typically used by buttons, such as JButton and JToggleButton.

If the same Action is used with menus and buttons you'll typically specify both a SMALL_ICON and a LARGE_ICON_KEY. The menu will use the SMALL_ICON and the button the LARGE_ICON_KEY.

Note: the value of this field is prefixed with 'Swing' to avoid possible collisions with existing Actions.
Since: 1.6

publicfinalstatic String LONG_DESCRIPTION = "LongDescription" [Inherited From Action]

The key used for storing a longer String description for the action, could be used for context-sensitive help.

publicfinalstatic String MNEMONIC_KEY = "MnemonicKey" [Inherited From Action]

The key used for storing an Integer that corresponds to one of the KeyEvent key codes.

The key used for storing an Integer that corresponds to
one of the KeyEvent key codes. The value is
commonly used to specify a mnemonic. For example:
myAction.putValue(Action.MNEMONIC_KEY, KeyEvent.VK_A)
sets the mnemonic of myAction to 'a'.
Since: 1.3

publicfinalstatic String NAME = "Name" [Inherited From Action]

The key used for storing the String name for the action, used for a menu or button.

publicfinalstatic String SELECTED_KEY = "SwingSelectedKey" [Inherited From Action]

The key used for storing a Boolean that corresponds to the selected state.

The key used for storing a Boolean that corresponds to the selected state. This is typically used only for components that have a meaningful selection state. For example, JRadioButton and JCheckBox make use of this but instances of JMenu don't.

This property differs from the others in that it is both read by the component and set by the component. For example, if an Action is attached to a JCheckBox the selected state of the JCheckBox will be set from that of the Action. If the user clicks on the JCheckBox the selected state of the JCheckBox and the Action will both be updated.

Note: the value of this field is prefixed with 'Swing' to avoid possible collisions with existing Actions.
Since: 1.6

publicfinalstatic String SHORT_DESCRIPTION = "ShortDescription" [Inherited From Action]

The key used for storing a short String description for the action, used for tooltip text.

publicfinalstatic String SMALL_ICON = "SmallIcon" [Inherited From Action]

The key used for storing a small Icon, such as ImageIcon.

The key used for storing a small Icon, such as ImageIcon. This is typically used with menus such as JMenuItem.

If the same Action is used with menus and buttons you'll typically specify both a SMALL_ICON and a LARGE_ICON_KEY. The menu will use the SMALL_ICON and the button will use the LARGE_ICON_KEY.
