<h1 class="chapter">2 Package Layout</h1>
<p>The Python X Library is distributed as a Python package, named
<code>Xlib</code>. It contains a number of modules providing the main
library interface:
</p>
<dl compact="compact">
<dt><code>display</code></dt>
<dd>
<p>Contains the <code>Display</code> class, providing the X connection and access
to all other X objects and operations.
</p>
</dd>
<dt><code>error</code></dt>
<dd>
<p>Contains all <code>Xlib</code> exception classes.
</p>
</dd>
<dt><code>threaded</code></dt>
<dd>
<p>Imported to set up the library to be thread-safe.
</p>
</dd>
<dt><code>rdb</code></dt>
<dd>
<p>Contains <code>ResourceDB</code>, an X resource database class, and related
code.
</p>
</dd>
<dt><code>X</code></dt>
<dd>
<p>Contains symbolic names for all basic X protocol constants.
</p>
</dd>
<dt><code>Xutil</code></dt>
<dd>
<p>Contains additional constants for mainly the ICCCM standard.
</p>
</dd>
<dt><code>XK</code></dt>
<dd>
<p>Contains symbolic names for all X keysyms.
</p>
</dd>
<dt><code>Xatom</code></dt>
<dd>
<p>Contains symbolic names for all standard X atoms.
</p>
</dd>
<dt><code>Xcursorfont</code></dt>
<dd>
<p>Contains symbolic names for all standard X fonts.
</p>
</dd>
</dl>
<p>There is also a number of subpackages, but they will mainly be of
interest to developers of the Xlib itself:
</p>
<dl compact="compact">
<dt><code>protocol</code></dt>
<dd>
<p>The low-level protocol implementation. Contains definitions of all X
request, responses, events and errors, in addition to the core network
code. The high-level object oriented interface provided by
<code>Xlib.display</code> is merely a wrapper around this package.
</p>
</dd>
<dt><code>support</code></dt>
<dd>
<p>Miscellaneous supporting code for handling threads and operating
system-specific features.
</p>
</dd>
<dt><code>xobject</code></dt>
<dd>
<p>Contains classes for all X objects, which are returned by various
display operations.
</p>
</dd>
<dt><code>ext</code></dt>
<dd>
<p>Contains various X protocol extensions. Extensions supported by the
server are loaded automatically at the display connection.
</p>
</dd>
</dl>
