/**
<unit>
<heading>NSWindow</heading>
<p> 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. </p>
<p> 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
<code>setContentView:</code> method, and accessed through the
<code>contentView</code> method. <code>setContentView:</code>
replaces the default content view created by NSWindow. </p>
<p> Other views may be added to the window by using the content
view's <code>addSubview:</code> 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. </p>
<p> A delegate can be specified for an NSWindow, which will receive
notifications of events pertaining to the window. The delegate is
set using <code>setDelegate:</code>, and can be retrieved using
<code>delegate</code>. The delegate can restrain resizing by
implementing the <code>windowWillResize: toSize:</code> method, or
control the closing of the window by implementing
<code>windowShouldClose:</code>. </p>
</unit>
