# NSWindow

Instances of the NSWindow class handle on-screen windows, their associated NSViews, and events generate by the user. An NSWindow's size is defined by its frame rectangle, which encompasses its entire structure, and its content rectangle, which includes only the content.

Every NSWindow has a content view, the NSView which forms the root of the window's view hierarchy. This view can be set using the `setContentView:` method, and accessed through the `contentView` method. `setContentView:` replaces the default content view created by NSWindow.

Other views may be added to the window by using the content view's `addSubview:` method. These subviews can also have subviews added, forming a tree structure, the view hierarchy. When an NSWindow must display itself, it causes this hierarchy to draw itself. Leaf nodes in the view hierarchy are drawn last, causing them to potentially obscure views further up in the hierarchy.

A delegate can be specified for an NSWindow, which will receive notifications of events pertaining to the window. The delegate is set using `setDelegate:`, and can be retrieved using `delegate`. The delegate can restrain resizing by implementing the `windowWillResize: toSize:` method, or control the closing of the window by implementing `windowShouldClose:`.

An NSWindow instance represents a window, panel or menu on the screen.
Each window has a style, which determines how the window is decorated: ie whether it has a border, a title bar, a resize bar, minimise and close buttons.

A window has a frame. This is the frame of the entire window on the screen, including all decorations and borders. The origin of the frame represents its bottom left corner and the frame is expressed in screen coordinates (see NSScreen ).

When a window is created, it has a private NSView instance which fills the entire window frame and whose coordinate system is the same as the base coordinate system of the window (ie zero x and y coordinates are at the bottom left corner of the window, with increasing x and y corresponding to points to the right and above the origin).
This view may be used by the library internals (and theme engines) to draw window decorations if the backend library is not handling the window decorations.

A window always contains a content view which is the highest level view available for public (application) use. This view fills the area of the window inside any decoration/border.
This is the only part of the window that application programmers are allowed to draw in directly.

You can convert between view coordinates and window base coordinates using the [NSView -convertPoint:fromView:] , [NSView -convertPoint:toView:] , [NSView -convertRect:fromView:] , and [NSView -convertRect:toView:] methods with a `nil` view argument.
You can convert between window and screen coordinates using the -convertBaseToScreen: and -convertScreenToBase: methods.

### level

- (NSInteger) level;
Availability: OpenStep
Description forthcoming.

### makeFirstResponder:

- (BOOL) makeFirstResponder: (NSResponder*)aResponder;
Availability: OpenStep
This method attempts to make aResponder the first responder.
If aResponder is already the first responder, this method has no effect and simply returns `YES`. Otherwise, the method sends a -resignFirstResponder message to the current first responder (if there is one) and immediately returns `NO` if the current first responder refuses to resign.
Then the method asks aResponder to become first responder by sending it a -becomeFirstResponder message, and if that returns `YES` then this method immediately returns `YES`.
However, if that returns `NO`, the receiver is made the first responder by sending it a -becomeFirstResponder message, and this method returns `NO`.
If aResponder is neither `nil` nor an instance of NSResponder (or of a subclass of NSResponder) then behavior is undefined (though the current GNUstep implementation just returns `NO`).
Makes aResponder the first responder within the receiver.

- (void) orderFront: (id)sender;
Availability: OpenStep
If the application is active, orders the window to the front in its level. If the application is not active, the window is ordered in as far forward as possible in its level without being ordered in front of the key or main window of the currently active app. The current key and main window status is not changed. Equivalent to -orderWindow:relativeTo: with arguments NSWindowAbove and 0.

### orderFrontRegardless

- (void) orderFrontRegardless;
Availability: OpenStep
Orders the window to the front in its level (even in front of the key and main windows of the current app) regardless of whether the app is current or not. This method should only be used in rare cases where the app is cooperating with another app that is displaying data for it. The current key and main window status is not changed.

### orderOut:

If place is NSWindowOut, removes the window from the screen. If place is NSWindowAbove, places the window directly above otherWin, or directly above all windows in its level if otherWin is 0. If place is NSWindowBelow, places the window directly below otherWin, or directly below all windows in its level if otherWin is 0.

If otherWin is zero and the key window is at the same window level as the receiver, the receiver cannot be positioned above the key window.

If place is NSWindowAbove or NSWindowBelow and the application is hidden, the application is unhidden.
