public void addPropertyChangeListener(PropertyChangeListener listener) {
super.addPropertyChangeListener(listener);
} Adds a PropertyChangeListener to the listener list. The listener is
registered for all bound properties of this class, including the
following:
- this Window's font ("font")
- this Window's background color ("background")
- this Window's foreground color ("foreground")
- this Window's focusability ("focusable")
- this Window's focus traversal keys enabled state
("focusTraversalKeysEnabled")

("forwardFocusTraversalKeys")
- this Window's Set of BACKWARD_TRAVERSAL_KEYS
("backwardFocusTraversalKeys")
- this Window's Set of UP_CYCLE_TRAVERSAL_KEYS
("upCycleFocusTraversalKeys")

("downCycleFocusTraversalKeys")
- this Window's focus traversal policy ("focusTraversalPolicy")
- this Window's focusable Window state ("focusableWindowState")
- this Window's always-on-top state("alwaysOnTop")
Note that if this Window is inheriting a bound property, then no
event will be fired in response to a change in the inherited property.
If listener is null, no exception is thrown and no action is performed. |
public void addPropertyChangeListener(String propertyName,
PropertyChangeListener listener) {
super.addPropertyChangeListener(propertyName, listener);
} Adds a PropertyChangeListener to the listener list for a specific
property. The specified property may be user-defined, or one of the
following:
- this Window's font ("font")
- this Window's background color ("background")
- this Window's foreground color ("foreground")
- this Window's focusability ("focusable")
- this Window's focus traversal keys enabled state
("focusTraversalKeysEnabled")
- this Window's Set of FORWARD_TRAVERSAL_KEYS
("forwardFocusTraversalKeys")
- this Window's Set of BACKWARD_TRAVERSAL_KEYS
("backwardFocusTraversalKeys")
- this Window's Set of UP_CYCLE_TRAVERSAL_KEYS
("upCycleFocusTraversalKeys")
- this Window's Set of DOWN_CYCLE_TRAVERSAL_KEYS
("downCycleFocusTraversalKeys")
- this Window's focus traversal policy ("focusTraversalPolicy")
- this Window's focusable Window state ("focusableWindowState")
- this Window's always-on-top state("alwaysOnTop")
Note that if this Window is inheriting a bound property, then no
event will be fired in response to a change in the inherited property.

} Construct a name for this component. Called by getName() when the
name is null. |
public void createBufferStrategy(int numBuffers) {
super.createBufferStrategy(numBuffers);
} Creates a new strategy for multi-buffering on this component.
Multi-buffering is useful for rendering performance. This method
attempts to create the best strategy available with the number of
buffers supplied. It will always create a BufferStrategy
with that number of buffers.
A page-flipping strategy is attempted first, then a blitting strategy
using accelerated buffers. Finally, an unaccelerated blitting
strategy is used.
Each time this method is called,
the existing buffer strategy for this component is discarded. |
public void createBufferStrategy(int numBuffers,
BufferCapabilities caps) throws AWTException {
super.createBufferStrategy(numBuffers, caps);
} Creates a new strategy for multi-buffering on this component with the
required buffer capabilities. This is useful, for example, if only
accelerated memory or page flipping is desired (as specified by the
buffer capabilities).
Each time this method
is called, the existing buffer strategy for this component is discarded. |
void deliverMouseWheelToAncestor(MouseWheelEvent e) {
} Overridden from Component. Top-level Windows should not propagate a
MouseWheelEvent beyond themselves into their owning Windows. |
void dispatchEventImpl(AWTEvent e) {

}
super.dispatchEventImpl(e);
} Dispatches an event to this window or one of its sub components. |
boolean dispatchMouseWheelToAncestor(MouseWheelEvent e) {
return false;
} Overridden from Component. Top-level Windows don't dispatch to ancestors |
public void dispose() {
doDispose();
} Releases all of the native screen resources used by this
Window, its subcomponents, and all of its owned
children. That is, the resources for these Components
will be destroyed, any memory they consume will be returned to the
OS, and they will be marked as undisplayable.
The Window and its subcomponents can be made displayable
again by rebuilding the native resources with a subsequent call to
pack or show. The states of the recreated
Window and its subcomponents will be identical to the
states of these objects at the point where the Window
was disposed (not accounting for additional modifications between
those actions).
Note: When the last displayable window
within the Java virtual machine (VM) is disposed of, the VM may
terminate. See
AWT Threading Issues for more information. |

} Always returns null because Windows have no ancestors; they
represent the top of the Component hierarchy. |
public Component getFocusOwner() {
return (isFocused())
? KeyboardFocusManager.getCurrentKeyboardFocusManager().
getFocusOwner()

if (keystrokes != null) {
return keystrokes;
} else {
return KeyboardFocusManager.getCurrentKeyboardFocusManager().
getDefaultFocusTraversalKeys(id);
}
} Gets a focus traversal key for this Window. (See
setFocusTraversalKeys for a full description of each key.)
If the traversal key has not been explicitly set for this Window,
then this Window's parent's traversal key is returned. If the
traversal key has not been explicitly set for any of this Window's
ancestors, then the current KeyboardFocusManager's default traversal key
is returned. |
public boolean getFocusableWindowState() {
return focusableWindowState;
} Returns whether this Window can become the focused Window if it meets
the other requirements outlined in isFocusableWindow. If
this method returns false, then
isFocusableWindow will return false as well.
If this method returns true, then
isFocusableWindow may return true or
false depending upon the other requirements which must be
met in order for a Window to be focusable.
By default, all Windows have a focusable Window state of
true. |
public GraphicsConfiguration getGraphicsConfiguration() {
//NOTE: for multiscreen, this will need to take into account

if (graphicsConfig == null && !GraphicsEnvironment.isHeadless()) {
graphicsConfig =
GraphicsEnvironment. getLocalGraphicsEnvironment().

public List getIconImages() {
java.util.List< Image > icons = this.icons;
if (icons == null || icons.size() == 0) {
return new ArrayList< Image >();
}
return new ArrayList< Image >(icons);
} Returns the sequence of images to be displayed as the icon for this window.
This method returns a copy of the internally stored list, so all operations
on the returned object will not affect the window's behavior. |
public InputContext getInputContext() {
synchronized (inputContextLock) {
if (inputContext == null) {
inputContext = InputContext.getInstance();
}
}
return inputContext;
} Gets the input context for this window. A window always has an input context,
which is shared by subcomponents unless they create and set their own. |

} else {
return super.getListeners(listenerType);
}
return AWTEventMulticaster.getListeners(l, listenerType);
} Returns an array of all the objects currently registered
as FooListeners
upon this Window.
FooListeners are registered using the
addFooListener method.
You can specify the listenerType argument
with a class literal, such as
FooListener.class.
For example, you can query a
Window w
for its window listeners with the following code:
WindowListener[] wls = (WindowListener[])(w.getListeners(WindowListener.class));
If no such listeners exist, this method returns an empty array. |
public Locale getLocale() {
if (this.locale == null) {
return Locale.getDefault();
}
return this.locale;
} Gets the Locale object that is associated
with this window, if the locale has been set.
If no locale has been set, then the default locale
is returned. |

return new Point(0, 0);
} |
Dialog getModalBlocker() {

if (mostRecent != null) {
return mostRecent;
} else {
return (isFocusableWindow())
? getFocusTraversalPolicy().getInitialComponent(this)
: null;
}
}
} Returns the child Component of this Window that will receive the focus
when this Window is focused. If this Window is currently focused, this
method returns the same Component as getFocusOwner(). If
this Window is not focused, then the child Component that most recently
requested focus will be returned. If no child Component has ever
requested focus, and this is a focusable Window, then this Window's
initial focusable Component is returned. If no child Component has ever
requested focus, and this is a non-focusable Window, null is returned. |
public Window[] getOwnedWindows() {
return getOwnedWindows_NoClientCode();
} Return an array containing all the windows this
window currently owns. |
final Window[] getOwnedWindows_NoClientCode() {
Window realCopy[];
synchronized(ownedWindowList) {
// Recall that ownedWindowList is actually a Vector of
// WeakReferences and calling get() on one of these references

}
}
return ownerless;
} Returns an array of all {@code Window}s created by this application
that have no owner. They include {@code Frame}s and ownerless
{@code Dialog}s and {@code Window}s.
If called from an applet, the array includes only the {@code Window}s
accessible by that applet.
Warning: this method may return system created windows, such
as a print dialog. Applications should not assume the existence of
these dialogs, nor should an application assume anything about these
dialogs such as component positions, LayoutManagers
or serialization. |
Component getTemporaryLostComponent() {
return temporaryLostComponent;
} |
public Toolkit getToolkit() {
return Toolkit.getDefaultToolkit();
} Returns the toolkit of this frame. |
public final String getWarningString() {
return warningString;
} Gets the warning string that is displayed with this window.
If this window is insecure, the warning string is displayed
somewhere in the visible area of the window. A window is
insecure if there is a security manager, and the security
manager's checkTopLevelWindow method returns
false when this window is passed to it as an
argument.
If the window is secure, then getWarningString
returns null. If the window is insecure, this
method checks for the system property
awt.appletWarning
and returns the string value of that property. |
public synchronized WindowFocusListener[] getWindowFocusListeners() {
return (WindowFocusListener[])(getListeners(WindowFocusListener.class));
} Returns an array of all the window focus listeners
registered on this window. |
public synchronized WindowListener[] getWindowListeners() {

} Returns an array of all the window listeners
registered on this window. |
public synchronized WindowStateListener[] getWindowStateListeners() {
return (WindowStateListener[])(getListeners(WindowStateListener.class));
} Returns an array of all the window state listeners
registered on this window. |
public static Window[] getWindows() {
return getWindows(AppContext.getAppContext());
} Returns an array of all {@code Window}s, both owned and ownerless,
created by this application.
If called from an applet, the array includes only the {@code Window}s
accessible by that applet.
Warning: this method may return system created windows, such
as a print dialog. Applications should not assume the existence of
these dialogs, nor should an application assume anything about these
dialogs such as component positions, LayoutManagers
or serialization. |

} Deprecated! As - of JDK version 1.5, replaced by
#setVisible(boolean) .
Hide this Window, its subcomponents, and all of its owned children.
The Window and its subcomponents can be made visible again
with a call to {@code show}.
|
public boolean isActive() {
return (KeyboardFocusManager.getCurrentKeyboardFocusManager().
getActiveWindow() == this);
} Returns whether this Window is active. Only a Frame or a Dialog may be
active. 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. |
public final boolean isAlwaysOnTop() {
return alwaysOnTop;
} Returns whether this window is an always-on-top window. |
public boolean isAlwaysOnTopSupported() {
return Toolkit.getDefaultToolkit().isAlwaysOnTopSupported();
} Returns whether the always-on-top mode is supported for this
window. Some platforms may not support always-on-top windows, some
may support only some kinds of top-level windows; for example,
a platform may not support always-on-top modal dialogs. |
public boolean isAutoRequestFocus() {
return autoRequestFocus;
} Returns whether this window should receive focus on subsequently being shown
(with a call to setVisible(true) ), or being moved to the front
(with a call to #toFront ).
By default, the window has {@code autoRequestFocus} value of {@code true}. |
public final boolean isFocusCycleRoot() {

if (owner instanceof Frame || owner instanceof Dialog) {
return owner.isShowing();
}
}
return false;
} Returns whether this Window can become the focused Window, that is,
whether this Window or any of its subcomponents can become the focus
owner. For a Frame or Dialog to be focusable, its focusable Window state
must be set to true. For a Window which is not a Frame or
Dialog to be focusable, its focusable Window state must be set to
true, its nearest owning Frame or Dialog must be
showing on the screen, and it must contain at least one Component in
its focus traversal cycle. If any of these conditions is not met, then
neither this Window nor any of its subcomponents can become the focus
owner. |
public boolean isFocused() {
return (KeyboardFocusManager.getCurrentKeyboardFocusManager().
getGlobalFocusedWindow() == this);
} Returns whether this Window is focused. If there exists a focus owner,
the focused Window is the Window that is, or contains, that focus owner.
If there is no focus owner, then no Window is focused.
If the focused Window is a Frame or a Dialog it is also the active
Window. Otherwise, the active Window is the first Frame or Dialog that
is an owner of the focused Window. |
public boolean isLocationByPlatform() {
synchronized (getTreeLock()) {
return locationByPlatform;
}
} Returns true if this Window will appear at the default location
for the native windowing system the next time this Window is made visible.
This method always returns false if the Window is showing on the
screen. |

} Causes this Window to be sized to fit the preferred size
and layouts of its subcomponents. The resulting width and
height of the window are automatically enlarged if either
of dimensions is less than the minimum size as specified
by the previous call to the {@code setMinimumSize} method.
If the window and/or its owner are not displayable yet,
both of them are made displayable before calculating
the preferred size. The Window is validated after its
size is being calculated. |

} Sets whether this window should always be above other windows. If
there are multiple always-on-top windows, their relative order is
unspecified and platform dependent.
If some other window is already always-on-top then the
relative order between these windows is unspecified (depends on
platform). No window can be brought to be over the always-on-top
window except maybe another always-on-top window.
All windows owned by an always-on-top window inherit this state and
automatically become always-on-top. If a window ceases to be
always-on-top, the windows that it owns will no longer be
always-on-top. When an always-on-top window is sent
toBack , its always-on-top state is set to false.
When this method is called on a window with a value of
true, and the window is visible and the platform
supports always-on-top for this window, the window is immediately
brought forward, "sticking" it in the top-most position. If the
window isn`t currently visible, this method sets the always-on-top
state to true but does not bring the window forward.
When the window is later shown, it will be always-on-top.
When this method is called on a window with a value of
false the always-on-top state is set to normal. The
window remains in the top-most position but it`s z-order can be
changed as for any other window. Calling this method with a value
of false on a window that has a normal state has no
effect. Setting the always-on-top state to false has no effect on
the relative z-order of the windows if there are no other
always-on-top windows.
Note: some platforms might not support always-on-top
windows. To detect if always-on-top windows are supported by the
current platform, use Toolkit#isAlwaysOnTopSupported() and
Window#isAlwaysOnTopSupported() . If always-on-top mode
isn't supported by the toolkit or for this window, calling this
method has no effect.
If a SecurityManager is installed, the calling thread must be
granted the AWTPermission "setWindowAlwaysOnTop" in
order to set the value of this property. If this
permission is not granted, this method will throw a
SecurityException, and the current value of the property will
be left unchanged. |
public void setAutoRequestFocus(boolean autoRequestFocus) {
this.autoRequestFocus = autoRequestFocus;
} Sets whether this window should receive focus on

or being moved to the front (with a call to #toFront ).
Note that setVisible(true) may be called indirectly
(e.g. when showing an owner of the window makes the window to be shown).
#toFront may also be called indirectly (e.g. when
setVisible(true) is called on already visible window).
In all such cases this property takes effect as well.
The value of the property is not inherited by owned windows. |

}
} Sets whether this Window can become the focused Window if it meets
the other requirements outlined in isFocusableWindow. If
this Window's focusable Window state is set to false, then
isFocusableWindow will return false. If this
Window's focusable Window state is set to true, then
isFocusableWindow may return true or
false depending upon the other requirements which must be
met in order for a Window to be focusable.
Setting a Window's focusability state to false is the
standard mechanism for an application to identify to the AWT a Window
which will be used as a floating palette or toolbar, and thus should be
a non-focusable Window.
Setting the focusability state on a visible Window
can have a delayed effect on some platforms — the actual
change may happen only when the Window becomes
hidden and then visible again. To ensure consistent behavior
across platforms, set the Window's focusable state
when the Window is invisible and then show it. |

firePropertyChange("iconImage", null, null);
} Sets the sequence of images to be displayed as the icon
for this window. Subsequent calls to {@code getIconImages} will
always return a copy of the {@code icons} list.
Depending on the platform capabilities one or several images
of different dimensions will be used as the window's icon.
The {@code icons} list is scanned for the images of most
appropriate dimensions from the beginning. If the list contains
several images of the same size, the first will be used.
Ownerless windows with no icon specified use platfrom-default icon.
The icon of an owned window may be inherited from the owner
unless explicitly overridden.
Setting the icon to {@code null} or empty list restores
the default behavior.
Note : Native windowing systems may use different images of differing
dimensions to represent a window, depending on the context (e.g.
window decoration, window list, taskbar, etc.). They could also use
just a single image for all contexts or no image at all. |

synchronized (getTreeLock()) {
if (locationByPlatform && isShowing()) {
throw new IllegalComponentStateException("The window is showing on screen.");
}
this.locationByPlatform = locationByPlatform;
}
} Sets whether this Window should appear at the default location for the
native windowing system or at the current location (returned by
getLocation) the next time the Window is made visible.
This behavior resembles a native window shown without programmatically
setting its location. Most windowing systems cascade windows if their
locations are not explicitly set. The actual location is determined once the
window is shown on the screen.
This behavior can also be enabled by setting the System Property
"java.awt.Window.locationByPlatform" to "true", though calls to this method
take precedence.
Calls to setVisible, setLocation and
setBounds after calling setLocationByPlatform clear
this property of the Window.
For example, after the following code is executed:
setLocationByPlatform(true);
setVisible(true);
boolean flag = isLocationByPlatform();
The window will be shown at platform's default location and
flag will be false.
In the following sample:
setLocationByPlatform(true);
setLocation(10, 10);
boolean flag = isLocationByPlatform();
setVisible(true);
The window will be shown at (10, 10) and flag will be
false. |

} Sets the location of the window relative to the specified
component according to the following scenarios.
The target screen mentioned below is a screen to which
the window should be placed after the setLocationRelativeTo
method is called.
- If the component is {@code null}, or the {@code
GraphicsConfiguration} associated with this component is
{@code null}, the window is placed in the center of the
screen. The center point can be obtained with the
GraphicsEnvironment.getCenterPoint method.
- If the component is not {@code null}, but it is not
currently showing, the window is placed in the center of
the target screen defined by the {@code
GraphicsConfiguration} associated with this component.
- If the component is not {@code null} and is shown on
the screen, then the window is located in such a way that
the center of the window coincides with the center of the
component.
If the screens configuration does not allow the window to
be moved from one screen to another, then the window is
only placed at the location determined according to the
above conditions and its {@code GraphicsConfiguration} is
not changed.
Note: If the lower edge of the window is out of the screen,
then the window is placed to the side of the Component
that is closest to the center of the screen. So if the
component is on the right part of the screen, the window
is placed to its left, and vice versa.
If after the window location has been calculated, the upper,
left, or right edge of the window is out of the screen,
then the window is located in such a way that the upper,
left, or right edge of the window coincides with the
corresponding edge of the screen. If both left and right
edges of the window are out of the screen, the window is
placed at the left side of the screen. The similar placement
will occur if both top and bottom edges are out of the screen.
In that case, the window is placed at the top side of the screen. |

if (peer != null) {

} Sets the minimum size of this window to a constant
value. Subsequent calls to {@code getMinimumSize}
will always return this value. If current window's
size is less than {@code minimumSize} the size of the
window is automatically enlarged to honor the minimum size.
If the {@code setSize} or {@code setBounds} methods
are called afterwards with a width or height less than
that was specified by the {@code setMinimumSize} method
the window is automatically enlarged to meet
the {@code minimumSize} value. The {@code minimumSize}

parameter to the {@code null} value.
