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:.
