when debug is active (#define __W32_debug__) the following
additional notifications are registered for in the backend server.
Helps to show where appevents and server
events are happening relitive to each other
NSWindowDidBecomeKeyNotification
Posted whenever an NSWindow becomes the key window.
The notification object is the NSWindow that has become key.
This notification does not contain a userInfo dictionary.
NSWindowDidBecomeMainNotification
Posted whenever an NSWindow becomes the main window.
The notification object is the NSWindow that has become main.
This notification does not contain a userInfo dictionary.
NSWindowDidChangeScreenNotification

or off of a screen.
The notification object is the NSWindow that has changed screens.
This notification does not contain a userInfo dictionary.
This notification is not sent in Mac OS X versions earlier than 10.4.
NSWindowDidChangeScreenProfileNotification
Posted whenever the display profile for the screen containing the window
changes.
This notification is sent only if the window returns YES from
displaysWhenScreenProfileChanges. This notification may be sent
when a majority of the window is moved to a different screen
(whose profile is also different from the previous screen) or when
the ColorSync profile for the current screen changes. The
notification object is the NSWindow whose profile changed. This
notification does not contain a userInfo dictionary.
NSWindowDidDeminiaturizeNotification
Posted whenever an NSWindow is deminiaturized.
The notification object is the NSWindow that has been deminiaturized. This
notification does not contain a userInfo dictionary.
NSWindowDidEndSheetNotification
Posted whenever an NSWindow closes an attached sheet.
The notification object is the NSWindow that contained the sheet. This
notification does not contain a userInfo dictionary.
NSWindowDidExposeNotification
Posted whenever a portion of a nonretained NSWindow is exposed,
whether by being ordered in front of other windows or by other
windows being removed from in front of it. The notification
object is the NSWindow that has been exposed. The userInfo
dictionary contains the following information: Key
@"NSExposedRect" Value The rectangle that has been exposed
(NSValue containing an NSRect).
NSWindowDidMiniaturizeNotification
Posted whenever an NSWindow is miniaturized.
The notification object is the NSWindow that has been miniaturized. This
notification does not contain a userInfo dictionary.
NSWindowDidMoveNotification
Posted whenever an NSWindow is moved.
The notification object is the NSWindow that has moved. This
notification does not contain a userInfo dictionary.
NSWindowDidResignKeyNotification
Posted whenever an NSWindow resigns its status as key window.
The notification object is the NSWindow that has resigned its key window
status. This notification does not contain a userInfo dictionary.
NSWindowDidResignMainNotification
Posted whenever an NSWindow resigns its status as main window.
The notification object is the NSWindow that has resigned its main window
status. This notification does not contain a userInfo dictionary.
NSWindowDidResizeNotification
Posted whenever an NSWindow<6F>s size changes.
The notification object is the NSWindow whose size has changed. This
notification does not contain a userInfo dictionary.
NSWindowDidUpdateNotification
Posted whenever an NSWindow receives an update message.
The notification object is the NSWindow that received the update
message. This notification does not contain a userInfo dictionary.
NSWindowWillBeginSheetNotification
Posted whenever an NSWindow is about to open a sheet.
The notification object is the NSWindow that is about to open the
sheet. This notification does not contain a userInfo dictionary.
NSWindowWillCloseNotification
Posted whenever an NSWindow is about to close.
The notification object is the NSWindow that is about to close. This
notification does not contain a userInfo dictionary.
NSWindowWillMiniaturizeNotification
Posted whenever an NSWindow is about to be miniaturized.
The notification object is the NSWindow that is about to be
miniaturized. This notification does not contain a userInfo
dictionary.
NSWindowWillMoveNotification
Posted whenever an NSWindow is about to move.
The notification object is the NSWindow that is about to move. This
notification does not contain a userInfo dictionary.

styleMask specifies the receiver's style. It can either be
NSBorderlessWindowMask, or it can contain any of the following
options, combined using the C bitwise OR operator: Option Meaning
NSTitledWindowMask The NSWindow displays a title bar.
NSClosableWindowMask The NSWindow displays a close button.
NSMiniaturizableWindowMask The NSWindow displays a miniaturize button.
NSResizableWindowMask The NSWindow displays a resize bar or border.

NSClosableWindowMask 2
NSMiniaturizableWindowMask 4
NSResizableWindowMask 8
NSIconWindowMask 64

Borderless windows display none of the usual peripheral elements and
are generally useful only for display or caching purposes; you
should normally not need to create them. Also, note that an
NSWindow's style mask should include NSTitledWindowMask if it
includes any of the others.
backingType specifies how the drawing done in the receiver is
buffered by the object's window device: NSBackingStoreBuffered
NSBackingStoreRetained NSBackingStoreNonretained
flag determines whether the Window Server creates a window device
for the new object immediately. If flag is YES, it defers creating
the window until the receiver is moved on screen. All display
messages sent to the NSWindow or its NSViews are postponed until the
window is created, just before it's moved on screen. Deferring the
creation of the window improves launch time and minimizes the
virtual memory load on the Window Server. The new NSWindow creates
an instance of NSView to be its default content view. You can
replace it with your own object by using the setContentView: method.
