final class DelegatingDefaultFocusManager

extends DefaultFocusManager

Provides a javax.swing.DefaultFocusManager view onto an arbitrary java.awt.KeyboardFocusManager. We subclass DefaultFocusManager instead of FocusManager because it seems more backward-compatible. It is likely that some pre-1.4 code assumes that the object returned by FocusManager.getCurrentManager is an instance of DefaultFocusManager unless set explicitly.

processKeyEvent

public void processKeyEvent(Component focusedComponent,
                            KeyEvent e)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: This method initiates a focus traversal operation if and only if the KeyEvent represents a focus traversal key for the specified focusedComponent. It is expected that focusedComponent is the current focus owner, although this need not be the case. If it is not, focus traversal will nevertheless proceed as if focusedComponent were the focus owner.

Overrides:

processKeyEvent in class DefaultKeyboardFocusManager

Parameters:

focusedComponent - the Component that is the basis for a focus traversal operation if the specified event represents a focus traversal key for the Component

e - the event that may represent a focus traversal key

focusNextComponent

public void focusNextComponent(Component aComponent)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: Focuses the Component after aComponent, typically based on a FocusTraversalPolicy.

Overrides:

focusNextComponent in class DefaultKeyboardFocusManager

Parameters:

aComponent - the Component that is the basis for the focus traversal operation

See Also:

FocusTraversalPolicy, Component.transferFocus()

focusPreviousComponent

public void focusPreviousComponent(Component aComponent)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: Focuses the Component before aComponent, typically based on a FocusTraversalPolicy.

Overrides:

focusPreviousComponent in class DefaultKeyboardFocusManager

Parameters:

aComponent - the Component that is the basis for the focus traversal operation

See Also:

FocusTraversalPolicy, Component.transferFocusBackward()

getFocusOwner

public Component getFocusOwner()

Description copied from class: KeyboardFocusManager

Suppressed: Returns the focus owner, if the focus owner is in the same context as the calling thread. The focus owner is defined as the Component in an application that will typically receive all KeyEvents generated by the user. KeyEvents which map to the focus owner's focus traversal keys will not be delivered if focus traversal keys are enabled for the focus owner. In addition, KeyEventDispatchers may retarget or consume KeyEvents before they reach the focus owner.

Overrides:

getFocusOwner in class KeyboardFocusManager

Returns:

the focus owner, or null if the focus owner is not a member of the calling thread's context

See Also:

KeyboardFocusManager.getGlobalFocusOwner(), KeyboardFocusManager.setGlobalFocusOwner(java.awt.Component)

clearGlobalFocusOwner

public void clearGlobalFocusOwner()

Description copied from class: KeyboardFocusManager

Suppressed: Clears the global focus owner at both the Java and native levels. If there exists a focus owner, that Component will receive a permanent FOCUS_LOST event. After this operation completes, the native windowing system will discard all user-generated KeyEvents until the user selects a new Component to receive focus, or a Component is given focus explicitly via a call to requestFocus(). This operation does not change the focused or active Windows.

Overrides:

clearGlobalFocusOwner in class KeyboardFocusManager

See Also:

Component.requestFocus(), java.awt.event.FocusEvent#FOCUS_LOST

getPermanentFocusOwner

public Component getPermanentFocusOwner()

Description copied from class: KeyboardFocusManager

Suppressed: Returns the permanent focus owner, if the permanent focus owner is in the same context as the calling thread. The permanent focus owner is defined as the last Component in an application to receive a permanent FOCUS_GAINED event. The focus owner and permanent focus owner are equivalent unless a temporary focus change is currently in effect. In such a situation, the permanent focus owner will again be the focus owner when the temporary focus change ends.

Overrides:

getPermanentFocusOwner in class KeyboardFocusManager

Returns:

the permanent focus owner, or null if the permanent focus owner is not a member of the calling thread's context

See Also:

KeyboardFocusManager.getGlobalPermanentFocusOwner(), KeyboardFocusManager.setGlobalPermanentFocusOwner(java.awt.Component)

getFocusedWindow

public Window getFocusedWindow()

Description copied from class: KeyboardFocusManager

Suppressed: Returns the focused Window, if the focused Window is in the same context as the calling thread. The focused Window is the Window that is or contains the focus owner.

Overrides:

getFocusedWindow in class KeyboardFocusManager

Returns:

the focused Window, or null if the focused Window is not a member of the calling thread's context

See Also:

KeyboardFocusManager.getGlobalFocusedWindow(), KeyboardFocusManager.setGlobalFocusedWindow(java.awt.Window)

getActiveWindow

public Window getActiveWindow()

Description copied from class: KeyboardFocusManager

Suppressed: Returns the active Window, if the active Window is in the same context as the calling thread. Only a Frame or a Dialog can be the active Window. The native windowing system may denote the active Window or its children with special decorations, such as a highlighted title bar. The active Window is always either the focused Window, or the first Frame or Dialog that is an owner of the focused Window.

Overrides:

getActiveWindow in class KeyboardFocusManager

Returns:

the active Window, or null if the active Window is not a member of the calling thread's context

See Also:

KeyboardFocusManager.getGlobalActiveWindow(), KeyboardFocusManager.setGlobalActiveWindow(java.awt.Window)

getDefaultFocusTraversalPolicy

public FocusTraversalPolicy getDefaultFocusTraversalPolicy()

Description copied from class: KeyboardFocusManager

Suppressed: Returns the default FocusTraversalPolicy. Top-level components use this value on their creation to initialize their own focus traversal policy by explicit call to Container.setFocusTraversalPolicy.

Overrides:

getDefaultFocusTraversalPolicy in class KeyboardFocusManager

Returns:

the default FocusTraversalPolicy. null will never be returned.

See Also:

KeyboardFocusManager.setDefaultFocusTraversalPolicy(java.awt.FocusTraversalPolicy), Container.setFocusTraversalPolicy(java.awt.FocusTraversalPolicy), Container.getFocusTraversalPolicy()

setDefaultFocusTraversalPolicy

public void setDefaultFocusTraversalPolicy(FocusTraversalPolicy defaultPolicy)

Description copied from class: KeyboardFocusManager

Suppressed: Sets the default FocusTraversalPolicy. Top-level components use this value on their creation to initialize their own focus traversal policy by explicit call to Container.setFocusTraversalPolicy. Note: this call doesn't affect already created components as they have their policy initialized. Only new components will use this policy as their default policy.

Overrides:

setDefaultFocusTraversalPolicy in class KeyboardFocusManager

Parameters:

defaultPolicy - the new, default FocusTraversalPolicy

See Also:

KeyboardFocusManager.getDefaultFocusTraversalPolicy(), Container.setFocusTraversalPolicy(java.awt.FocusTraversalPolicy), Container.getFocusTraversalPolicy()

setDefaultFocusTraversalKeys

public void setDefaultFocusTraversalKeys(int id,
                                         Set keystrokes)

Description copied from class: KeyboardFocusManager

Enabled: Sets the default focus traversal keys for a given traversal operation. This traversal key Set will be in effect on all Windows that have no such Set of their own explicitly defined. This Set will also be inherited, recursively, by any child Component of those Windows that has no such Set of its own explicitly defined.

The default values for the default focus traversal keys are implementation-dependent. Sun recommends that all implementations for a particular native platform use the same default values. The recommendations for Windows and Unix are listed below. These recommendations are used in the Sun AWT implementations.

Identifier	Meaning	Default
KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS	Normal forward keyboard traversal	TAB on KEY_PRESSED, CTRL-TAB on KEY_PRESSED
KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS	Normal reverse keyboard traversal	SHIFT-TAB on KEY_PRESSED, CTRL-SHIFT-TAB on KEY_PRESSED
KeyboardFocusManager.UP_CYCLE_TRAVERSAL_KEYS	Go up one focus traversal cycle	none
KeyboardFocusManager.DOWN_CYCLE_TRAVERSAL_KEYS	Go down one focus traversal cycle	none

To disable a traversal key, use an empty Set; Collections.EMPTY_SET is recommended.

Using the AWTKeyStroke API, client code can specify on which of two specific KeyEvents, KEY_PRESSED or KEY_RELEASED, the focus traversal operation will occur. Regardless of which KeyEvent is specified, however, all KeyEvents related to the focus traversal key, including the associated KEY_TYPED event, will be consumed, and will not be dispatched to any Component. It is a runtime error to specify a KEY_TYPED event as mapping to a focus traversal operation, or to map the same event to multiple default focus traversal operations.

Overrides:

setDefaultFocusTraversalKeys in class KeyboardFocusManager

Parameters:

id - one of KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, KeyboardFocusManager.UP_CYCLE_TRAVERSAL_KEYS, or KeyboardFocusManager.DOWN_CYCLE_TRAVERSAL_KEYS

keystrokes - the Set of AWTKeyStrokes for the specified operation

See Also:

KeyboardFocusManager.getDefaultFocusTraversalKeys(int), Component.setFocusTraversalKeys(int, java.util.Set), Component.getFocusTraversalKeys(int)

getDefaultFocusTraversalKeys

public Set getDefaultFocusTraversalKeys(int id)

Description copied from class: KeyboardFocusManager

Suppressed: Returns a Set of default focus traversal keys for a given traversal operation. This traversal key Set will be in effect on all Windows that have no such Set of their own explicitly defined. This Set will also be inherited, recursively, by any child Component of those Windows that has no such Set of its own explicitly defined. (See setDefaultFocusTraversalKeys for a full description of each operation.)

Overrides:

getDefaultFocusTraversalKeys in class KeyboardFocusManager

Parameters:

id - one of KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, KeyboardFocusManager.UP_CYCLE_TRAVERSAL_KEYS, or KeyboardFocusManager.DOWN_CYCLE_TRAVERSAL_KEYS

Returns:

the Set of AWTKeyStrokes for the specified operation; the Set will be unmodifiable, and may be empty; null will never be returned

See Also:

KeyboardFocusManager.setDefaultFocusTraversalKeys(int, java.util.Set), Component.setFocusTraversalKeys(int, java.util.Set), Component.getFocusTraversalKeys(int)

getCurrentFocusCycleRoot

public Container getCurrentFocusCycleRoot()

Description copied from class: KeyboardFocusManager

Suppressed: Returns the current focus cycle root, if the current focus cycle root is in the same context as the calling thread. If the focus owner is itself a focus cycle root, then it may be ambiguous as to which Components represent the next and previous Components to focus during normal focus traversal. In that case, the current focus cycle root is used to differentiate among the possibilities.

This method is intended to be used only by KeyboardFocusManagers and focus implementations. It is not for general client use.

Overrides:

getCurrentFocusCycleRoot in class KeyboardFocusManager

Returns:

the current focus cycle root, or null if the current focus cycle root is not a member of the calling thread's context

See Also:

KeyboardFocusManager.getGlobalCurrentFocusCycleRoot(), KeyboardFocusManager.setGlobalCurrentFocusCycleRoot(java.awt.Container)

setGlobalCurrentFocusCycleRoot

public void setGlobalCurrentFocusCycleRoot(Container newFocusCycleRoot)

Description copied from class: KeyboardFocusManager

Suppressed: Sets the current focus cycle root. If the focus owner is itself a focus cycle root, then it may be ambiguous as to which Components represent the next and previous Components to focus during normal focus traversal. In that case, the current focus cycle root is used to differentiate among the possibilities.

This method is intended to be used only by KeyboardFocusManagers and focus implementations. It is not for general client use.

Overrides:

setGlobalCurrentFocusCycleRoot in class KeyboardFocusManager

Parameters:

newFocusCycleRoot - the new focus cycle root

KeyboardFocusManager.getCurrentFocusCycleRoot(), KeyboardFocusManager.getGlobalCurrentFocusCycleRoot()

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

addKeyEventDispatcher

public void addKeyEventDispatcher(KeyEventDispatcher dispatcher)

Description copied from class: KeyboardFocusManager

Suppressed: Adds a KeyEventDispatcher to this KeyboardFocusManager's dispatcher chain. This KeyboardFocusManager will request that each KeyEventDispatcher dispatch KeyEvents generated by the user before finally dispatching the KeyEvent itself. KeyEventDispatchers will be notified in the order in which they were added. Notifications will halt as soon as one KeyEventDispatcher returns true from its dispatchKeyEvent method. There is no limit to the total number of KeyEventDispatchers which can be added, nor to the number of times which a particular KeyEventDispatcher instance can be added.

If a null dispatcher is specified, no action is taken and no exception is thrown.

Overrides:

addKeyEventDispatcher in class KeyboardFocusManager

Parameters:

dispatcher - the KeyEventDispatcher to add to the dispatcher chain

See Also:

KeyboardFocusManager.removeKeyEventDispatcher(java.awt.KeyEventDispatcher)

removeKeyEventDispatcher

public void removeKeyEventDispatcher(KeyEventDispatcher dispatcher)

Description copied from class: KeyboardFocusManager

Suppressed: Removes a KeyEventDispatcher which was previously added to this KeyboardFocusManager's dispatcher chain. This KeyboardFocusManager cannot itself be removed, unless it was explicitly re-registered via a call to addKeyEventDispatcher.

If a null dispatcher is specified, if the specified dispatcher is not in the dispatcher chain, or if this KeyboardFocusManager is specified without having been explicitly re-registered, no action is taken and no exception is thrown.

Overrides:

removeKeyEventDispatcher in class KeyboardFocusManager

Parameters:

dispatcher - the KeyEventDispatcher to remove from the dispatcher chain

See Also:

KeyboardFocusManager.addKeyEventDispatcher(java.awt.KeyEventDispatcher)

dispatchEvent

public boolean dispatchEvent(AWTEvent e)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: This method is called by the AWT event dispatcher requesting that the current KeyboardFocusManager dispatch the specified event on its behalf. DefaultKeyboardFocusManagers dispatch all FocusEvents, all WindowEvents related to focus, and all KeyEvents. These events are dispatched based on the KeyboardFocusManager's notion of the focus owner and the focused and active Windows, sometimes overriding the source of the specified AWTEvent. If this method returns false, then the AWT event dispatcher will attempt to dispatch the event itself.

Overrides:

dispatchEvent in class DefaultKeyboardFocusManager

Parameters:

e - the AWTEvent to be dispatched

Returns:

true if this method dispatched the event; false otherwise

dispatchKeyEvent

public boolean dispatchKeyEvent(KeyEvent e)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: Called by dispatchEvent if no other KeyEventDispatcher in the dispatcher chain dispatched the KeyEvent, or if no other KeyEventDispatchers are registered. If the event has not been consumed, its target is enabled, and the focus owner is not null, this method dispatches the event to its target. This method will also subsequently dispatch the event to all registered KeyEventPostProcessors.

In all cases, this method returns true, since DefaultKeyboardFocusManager is designed so that neither dispatchEvent, nor the AWT event dispatcher, should take further action on the event in any situation.

Specified by:

dispatchKeyEvent in interface KeyEventDispatcher

Overrides:

dispatchKeyEvent in class DefaultKeyboardFocusManager

Parameters:

e - the KeyEvent to be dispatched

Returns:

true

See Also:

Component.dispatchEvent(java.awt.AWTEvent)

upFocusCycle

public void upFocusCycle(Component aComponent)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: Moves the focus up one focus traversal cycle. Typically, the focus owner is set to aComponent's focus cycle root, and the current focus cycle root is set to the new focus owner's focus cycle root. If, however, aComponent's focus cycle root is a Window, then the focus owner is set to the focus cycle root's default Component to focus, and the current focus cycle root is unchanged.

Overrides:

upFocusCycle in class DefaultKeyboardFocusManager

Parameters:

aComponent - the Component that is the basis for the focus traversal operation

See Also:

Component.transferFocusUpCycle()

downFocusCycle

public void downFocusCycle(Container aContainer)

Description copied from class: DefaultKeyboardFocusManager

Suppressed: Moves the focus down one focus traversal cycle. If aContainer is a focus cycle root, then the focus owner is set to aContainer's default Component to focus, and the current focus cycle root is set to aContainer. If aContainer is not a focus cycle root, then no focus traversal operation occurs.

Overrides:

downFocusCycle in class DefaultKeyboardFocusManager

See Also:

Container.transferFocusDownCycle()
