<p>
NSView is an abstract class which provides facilities
for drawing in a window and receiving events. It is the
superclass of many of the visual elements of the
GUI.
</p>
<p>
In order to display itself, a view must be placed in a
window (represented by an NSWindow object). Within the
window is a hierarchy of NSViews, headed by the window's
content view. Every other view in a window is a
descendant of this view.
</p>
<p>
Subclasses can override
<ref type="method" id="-drawRect:">
-drawRect:
</ref>
in order to implement their appearance. Other methods of
NSView and NSResponder can also be overridden to handle
user generated events.

<br /> The event messages are sent to
<var>anObject</var>, which is <em>not</em> retained
and must therefore be sure to remove any tracking
rectangles using it before it is deallocated.

generated. <br /> If <var>flag</var> is

Tell the view to maintain a private gstate object

drawing, such as coordinate transforms, line
widths, etc. If you do not invoke this method, a
gstate object is constructed each time the view is
lockFocused. Allocating a private gstate may
improve the performance of views that are focused
a lot and have a lot of customized drawing parameters.

View subclasses should override the setUpGstate

Finds the nearest enclosing NSClipView and, if the

NSClipView in the direction of the event. The
amount scrolled is proportional to how far outside
the NSClipView the event's location is. This method is

0.1 seconds.

<sel>beginDocument</sel>
<desc>
Writes header and job information for the PostScript
document. This includes at a minimum, PostScript
header information. It may also include job setup
information if the output is intended for a
printer (i.e. not an EPS file). Most of the
information for writing the header comes from
the NSPrintOperation and NSPrintInfo objects associated
with the current print operation. There isn't normally
anything that the program needs to override at the
beginning of a document, although if there is
additional setup that needs to be done, you can
override the NSView's methods endHeaderComments,
endPrologue, beginSetup, and/or endSetup. This
method calls the above methods in the listed order
before or after writing the required information.
For an EPS operation, the beginSetup and endSetup
methods aren't used.

<desc>
This method is invoked to handle drawing inside the
view. The default NSView's implementation does
nothing; subclasses might override it to draw
something inside the view. Since NSView's
implementation is guaranteed to be empty,
you should not call super's implementation when you
override it in subclasses. drawRect: is invoked
when the focus has already been locked on the view;
you can use arbitrary postscript functions in drawRect:
to draw inside your view; the coordinate system in which
you draw is the view's own coordinate system (this
means for example that you should refer to the
rectangle covered by the view using its bounds,
and not its frame). The argument of drawRect: is the
rectangle which needs to be redrawn. In a lossy
implementation, you can ignore the argument
and redraw the whole view; if you are aiming at
performance, you may want to redraw only what
is inside the rectangle which needs to be redrawn; this
usually improves drawing performance considerably.

This methods is intended to be overriden so that it
can return a context-sensitive for appropriate

used for any kind of event)
</p>
<p>
This method is used by NSView's rightMouseDown:
method, and the returned NSMenu is displayed as a
context menu
</p>
<p>
Use of this method is discouraged in GNUstep as it
breaks many user interface guidelines. At the very
least, menu items that appear in a context
sensitive menu should also always appear in a
normal menu. Otherwise, users are faced with an
inconsistant interface where the menu items
they want are only available in certain (possibly
unknown) cases, making it difficult for the user
to understand how the application operates

As an exception to the general rules for threads and

<arg type="NSView*">aView</arg>

<p>
The effect of the
<ref type="method" id="-setNextKeyView:">
-setNextKeyView:
</ref>
method is to set <var>aView</var> to be the value
returned by subsequent calls to the receivers
<ref type="method" id="-nextKeyView">
-nextKeyView
</ref>
method. This also has the effect of setting the
previous key view of <var>aView</var>, so that
subsequent calls to its
<ref type="method" id="-previousKeyView">
-previousKeyView
</ref>
method will return the receiver.
</p>
<p>
As a special case, if you pass <code>nil</code> as
<var>aView</var> then the
<ref type="method" id="-previousKeyView">
-previousKeyView
</ref>
of the receivers current
<ref type="method" id="-nextKeyView">
-nextKeyView
</ref>
is set to <code>nil</code> as well as the receivers
<ref type="method" id="-nextKeyView">
-nextKeyView
</ref>
being set to <code>nil</code>. <br /> This behavior
provides MacOS-X compatibility.
</p>
<p>
If you pass a non-view object other than
<code>nil</code>, an
NSInternaInconsistencyException
is raised.
</p>
<p>
<strong>NB</strong> This method does
<em>NOT</em> cause <var>aView</var> to be retained,
and if <var>aView</var> is deallocated, the
<ref type="method" id="-dealloc" class="NSView">
[NSView -dealloc]
</ref>
method will automatically remove it from the key
view chain it is in.
</p>
<p>
For keyboard navigation, views are linked together in
a chain, so that the current first responder view can
be changed by stepping backward and forward in that
chain. This is the method for building and
modifying that chain.
</p>
<p>
The MacOS-X documentation refers to this chain as a
<em>loop</em>, but the actual implementation is not
a loop at all (except as a special case when you make
the chain into a loop). In fact, while each view may
have only zero or one <em>next</em> view, and zero
or one <em>previous</em> view, several views may have
their <em>next</em> view set to a single view
and/or their <em>previous</em> views set to a
single view. So the actual setup is a directed
graph rather than a loop.
</p>
<p>
While a directed graph is a very powerful and
flexible way of managing the way views get
keyboard focus in response to tabs etc, it can
be confusing if misused. It is probably best
therefore, to set your views up as a single
loop within each window.
</p>

[a setNextKeyView: b];
[b setNextKeyView: c];
[c setNextKeyView: d];
[d setNextKeyView: a];
