A FocusTraversalPolicy which provides support for legacy applications which handle focus traversal via JComponent.setNextFocusableComponent or by installing a custom DefaultFocusManager. If a specific traversal has not been hard coded, then that traversal is provided either by the custom DefaultFocusManager, or by a wrapped FocusTraversalPolicy instance.

getComponentAfterback to summary
public Component getComponentAfter(Container focusCycleRoot, Component aComponent)

Implements abstract java.awt.FocusTraversalPolicy.getComponentAfter.

Doc from java.awt.FocusTraversalPolicy.getComponentAfter.

Returns the Component that should receive the focus after aComponent. aContainer must be a focus cycle root of aComponent or a focus traversal policy provider.

getComponentBeforeback to summary
public Component getComponentBefore(Container focusCycleRoot, Component aComponent)

Implements abstract java.awt.FocusTraversalPolicy.getComponentBefore.

Doc from java.awt.FocusTraversalPolicy.getComponentBefore.

Returns the Component that should receive the focus before aComponent. aContainer must be a focus cycle root of aComponent or a focus traversal policy provider.

getDefaultComponentback to summary
public Component getDefaultComponent(Container focusCycleRoot)

Implements abstract java.awt.FocusTraversalPolicy.getDefaultComponent.

Doc from java.awt.FocusTraversalPolicy.getDefaultComponent.

Returns the default Component to focus. This Component will be the first to receive focus when traversing down into a new focus traversal cycle rooted at aContainer.

getFirstComponentback to summary
public Component getFirstComponent(Container focusCycleRoot)

Implements abstract java.awt.FocusTraversalPolicy.getFirstComponent.

Doc from java.awt.FocusTraversalPolicy.getFirstComponent.

Returns the first Component in the traversal cycle. This method is used to determine the next Component to focus when traversal wraps in the forward direction.

getLastComponentback to summary
public Component getLastComponent(Container focusCycleRoot)

Implements abstract java.awt.FocusTraversalPolicy.getLastComponent.

Doc from java.awt.FocusTraversalPolicy.getLastComponent.

Returns the last Component in the traversal cycle. This method is used to determine the next Component to focus when traversal wraps in the reverse direction.
