TextAction

Class Overview

An Action implementation useful for key bindings that are shared across a number of different text components. Because the action is shared, it must have a way of getting it's target to act upon. This class provides support to try and find a text component to operate on. The preferred way of getting the component to act upon is through the ActionEvent that is received. If the Object returned by getSource can be narrowed to a text component, it will be used. If the action event is null or can't be narrowed, the last focused text component is tried. This is determined by being used in conjunction with a JTextController which arranges to share that information with a TextAction.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.

Summary

[Expand] Inherited Constants

From interface javax.swing.Action String ACCELERATOR_KEY The key used for storing a KeyStroke to be used as the accelerator for the action. String ACTION_COMMAND_KEY 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. String DEFAULT Not currently used. String DISPLAYED_MNEMONIC_INDEX_KEY 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. String LARGE_ICON_KEY The key used for storing an Icon. String LONG_DESCRIPTION The key used for storing a longer String description for the action, could be used for context-sensitive help. String MNEMONIC_KEY The key used for storing an Integer that corresponds to one of the KeyEvent key codes. String NAME The key used for storing the String name for the action, used for a menu or button. String SELECTED_KEY The key used for storing a Boolean that corresponds to the selected state. String SHORT_DESCRIPTION The key used for storing a short String description for the action, used for tooltip text. String SMALL_ICON The key used for storing a small Icon, such as ImageIcon.

[Expand] Inherited Methods
From class javax.swing.AbstractAction synchronized void addPropertyChangeListener(PropertyChangeListener listener) Adds a PropertyChangeListener to the listener list. Object clone() Clones the abstract action. void firePropertyChange(String propertyName, Object oldValue, Object newValue) Supports reporting bound property changes. 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. synchronized PropertyChangeListener[] getPropertyChangeListeners() Returns an array of all the PropertyChangeListeners added to this AbstractAction with addPropertyChangeListener(). Object getValue(String key) Gets the Object associated with the specified key. boolean isEnabled() Returns true if the action is enabled. void putValue(String key, Object newValue) Sets the Value associated with the specified key. synchronized void removePropertyChangeListener(PropertyChangeListener listener) Removes a PropertyChangeListener from the listener list. void setEnabled(boolean newValue) Sets whether the Action is enabled.
From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
From interface java.awt.event.ActionListener abstract void actionPerformed(ActionEvent e) Invoked when an action occurs.
From interface javax.swing.Action abstract void addPropertyChangeListener(PropertyChangeListener listener) Adds a PropertyChange listener. abstract Object getValue(String key) Gets one of this object's properties using the associated key. abstract boolean isEnabled() Returns the enabled state of the Action. abstract void putValue(String key, Object value) Sets one of this object's properties using the associated key. abstract void removePropertyChangeListener(PropertyChangeListener listener) Removes a PropertyChange listener. abstract void setEnabled(boolean b) Sets the enabled state of the Action.
