2 Package Layout

The Python X Library is distributed as a Python package, named Xlib. It contains a number of modules providing the main library interface:

display

Contains the Display class, providing the X connection and access to all other X objects and operations.

error

Contains all Xlib exception classes.

threaded

Imported to set up the library to be thread-safe.

rdb

Contains ResourceDB, an X resource database class, and related code.

X

Contains symbolic names for all basic X protocol constants.

Xutil

Contains additional constants for mainly the ICCCM standard.

XK

Contains symbolic names for all X keysyms.

Xatom

Contains symbolic names for all standard X atoms.

Xcursorfont

Contains symbolic names for all standard X fonts.

There is also a number of subpackages, but they will mainly be of interest to developers of the Xlib itself:

protocol

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 Xlib.display is merely a wrapper around this package.

support

Miscellaneous supporting code for handling threads and operating system-specific features.

xobject

Contains classes for all X objects, which are returned by various display operations.

ext

Contains various X protocol extensions. Extensions supported by the server are loaded automatically at the display connection.
