public class Window extends Container implements Accessible
Window object is a top-level window with no borders and no
 menubar.
 The default layout for a window is BorderLayout.
 A window must have either a frame, dialog, or another window defined as its owner when it's constructed.
 In a multi-screen environment, you can create a Window
 on a different screen device by constructing the Window
 with Window(Window, GraphicsConfiguration).  The
 GraphicsConfiguration object is one of the
 GraphicsConfiguration objects of the target screen device.
 
In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of all configurations are relative to the virtual device coordinate system. The origin of the virtual-coordinate system is at the upper left-hand corner of the primary physical screen. Depending on the location of the primary screen in the virtual device, negative coordinates are possible, as shown in the following figure.
  
 
 In such an environment, when calling setLocation,
 you must pass a virtual coordinate to this method.  Similarly,
 calling getLocationOnScreen on a Window returns
 virtual device coordinates.  Call the getBounds method
 of a GraphicsConfiguration to find its origin in the virtual
 coordinate system.
 
 The following code sets the location of a Window
 at (10, 10) relative to the origin of the physical screen
 of the corresponding GraphicsConfiguration.  If the
 bounds of the GraphicsConfiguration is not taken
 into account, the Window location would be set
 at (10, 10) relative to the virtual-coordinate system and would appear
 on the primary physical screen, which might be different from the
 physical screen of the specified GraphicsConfiguration.
 
      Window w = new Window(Window owner, GraphicsConfiguration gc);
      Rectangle bounds = gc.getBounds();
      w.setLocation(10 + bounds.x, 10 + bounds.y);
 
 
 Note: the location and size of top-level windows (including
 Windows, Frames, and Dialogs)
 are under the control of the desktop's window management system.
 Calls to setLocation, setSize, and
 setBounds are requests (not directives) which are
 forwarded to the window management system.  Every effort will be
 made to honor such requests.  However, in some cases the window
 management system may ignore such requests, or modify the requested
 geometry in order to place and size the Window in a way
 that more closely matches the desktop settings.
 
 Due to the asynchronous nature of native event handling, the results
 returned by getBounds, getLocation,
 getLocationOnScreen, and getSize might not
 reflect the actual geometry of the Window on screen until the last
 request has been processed.  During the processing of subsequent
 requests these values might change accordingly while the window
 management system fulfills the requests.
 
 An application may set the size and location of an invisible
 Window arbitrarily, but the window management system may
 subsequently change its size and/or location when the
 Window is made visible. One or more ComponentEvents
 will be generated to indicate the new geometry.
 
Windows are capable of generating the following WindowEvents: WindowOpened, WindowClosed, WindowGainedFocus, WindowLostFocus.

getIconImages will
 always return a copy of the icons list.
 Depending on the platform capabilities one or several images of different dimensions will be used as the window's icon.
 The 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 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.

 This method can be used instead of setIconImages()
 to specify a single image as a window's icon.
 
The following statement:

 is equivalent to:
 
     ArrayList<Image> imageList = new ArrayList<Image>();

 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.
public void setMinimumSize(Dimension minimumSize)
getMinimumSize
 will always return this value. If current window's
 size is less than minimumSize the size of the
 window is automatically enlarged to honor the minimum size.
 
 If the setSize or setBounds methods
 are called afterwards with a width or height less than
 that was specified by the setMinimumSize method
 the window is automatically enlarged to meet
 the minimumSize value. The minimumSize
 value also affects the behaviour of the pack method.
 
 The default behavior is restored by setting the minimum size
 parameter to the null value.
 
 Resizing operation may be restricted if the user tries
 to resize window below the minimumSize value.
 This behaviour is platform-dependent.

show()public void toFront()
Places this Window at the top of the stacking order and shows it in front of any other Windows in this VM. No action will take place if this Window is not visible. Some platforms do not allow Windows which own other Windows to appear on top of those owned Windows. Some platforms may not permit this VM to place its Windows above windows of native applications, or Windows of other VMs. This permission may depend on whether a Window in this VM is already focused. Every attempt will be made to move this Window as high as possible in the stacking order; however, developers should not assume that this method will move this Window above all other windows in every situation.
Developers must never assume that this Window is the focused or active Window until this Window receives a WINDOW_GAINED_FOCUS or WINDOW_ACTIVATED event. On platforms where the top-most window is the focused window, this method will probably focus this Window (if it is not already focused) under the following conditions:

 If this method causes this Window to be focused, and this Window is a Frame or a Dialog, it will also become activated. If this Window is focused, but it is not a Frame or a Dialog, then the first Frame or Dialog that is an owner of this Window will be activated.
If this window is blocked by modal dialog, then the blocking dialog is brought to the front and remains above the blocked window.

Places this Window at the bottom of the stacking order and shows it behind any other Windows in this VM. No action will take place is this Window is not visible. Some platforms do not allow Windows which are owned by other Windows to appear below their owners. Every attempt will be made to move this Window as low as possible in the stacking order; however, developers should not assume that this method will move this Window below all other windows in every situation.
Because of variations in native windowing systems, no guarantees about changes to the focused and active Windows can be made. Developers must never assume that this Window is no longer the focused or active Window until this Window receives a WINDOW_LOST_FOCUS or WINDOW_DEACTIVATED event. On platforms where the top-most window is the focused window, this method will probably cause this Window to lose focus. In that case, the next highest, focusable Window in this VM will receive focus. On platforms where the stacking order does not typically affect the focused window, this method will probably leave the focused and active Windows unchanged.

                          throws SecurityException
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. It may also
 cause an unspecified, platform-dependent change in the z-order of
 top-level windows, but other always-on-top windows will remain in
 top-most position. Calling this method with a value of false
 on a window that has a normal state has no effect.
 
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
 isAlwaysOnTopSupported().  If always-on-top mode
 isn't supported for this window or this window's toolkit does not
 support always-on-top windows, 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.

 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.

 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 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.

 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

 Setting a shape cuts off some parts of the window. Only the parts that

GraphicsDevice.WindowTranslucencypublic void setBackground(Color bgColor)
 If the windowing system supports the PERPIXEL_TRANSLUCENT
 translucency, the alpha component of the given background color
 may effect the mode of operation for this window: it indicates whether
 this window must be opaque (alpha equals 1.0f) or per-pixel translucent
 (alpha is less than 1.0f). If the given background color is
 null, the window is considered completely opaque.
 
All the following conditions must be met to enable the per-pixel transparency mode for this window:
PERPIXEL_TRANSLUCENT translucency must be supported by the graphics
 device where this window is located
 Frame.setUndecorated(boolean)
 and Dialog.setUndecorated(boolean))
 GraphicsDevice.setFullScreenWindow(Window))
 
 If the alpha component of the requested background color is less than
 1.0f, and any of the above conditions are not met, the background
 color of this window will not change, the alpha component of the given
 background color will not affect the mode of operation for this window,
 and either the UnsupportedOperationException or IllegalComponentStateException will be thrown.
 
 When the window is per-pixel translucent, the drawing sub-system
 respects the alpha value of each individual pixel. If a pixel gets
 painted with the alpha color component equal to zero, it becomes
 visually transparent. If the alpha of the pixel is equal to 1.0f, the
 pixel is fully opaque. Interim values of the alpha color component make
 the pixel semi-transparent. In this mode, the background of the window
 gets painted with the alpha value of the given background color. If the
 alpha value of the argument of this method is equal to 0, the
 background is not painted at all.
 
 The actual level of translucency of a given pixel also depends on window
 opacity (see setOpacity(float)), as well as the current shape of
 this window (see setShape(Shape)).
 
 Note that painting a pixel with the alpha value of 0 may or may
 not disable the mouse event handling on this pixel. This is a
 platform-dependent behavior. To make sure the mouse events do not get
 dispatched to a particular pixel, the pixel must be excluded from the
 shape of the window.
