Class Overview

A FocusTraversalPolicy which can optionally provide an algorithm for determining a JInternalFrame's initial Component. The initial Component is the first to receive focus when the JInternalFrame is first selected. By default, this is the same as the JInternalFrame's default Component to focus.

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.

Public Constructors

public InternalFrameFocusTraversalPolicy ()

Public Methods

public Component getInitialComponent (JInternalFrame frame)

Returns the Component that should receive the focus when a JInternalFrame is selected for the first time. Once the JInternalFrame has been selected by a call to setSelected(true), the initial Component will not be used again. Instead, if the JInternalFrame loses and subsequently regains selection, or is made invisible or undisplayable and subsequently made visible and displayable, the JInternalFrame's most recently focused Component will become the focus owner. The default implementation of this method returns the JInternalFrame's default Component to focus.

Parameters

frame	the JInternalFrame whose initial Component is to be returned

Returns

the Component that should receive the focus when frame is selected for the first time, or null if no suitable Component can be found

Throws

IllegalArgumentException	if window is null
