From Qtile web site:
- Qtile is a full-featured, hackable tiling window manager written in Python. Qtile is simple, small, and extensible. It's easy to write your own layouts, widgets, and built-in commands.It is written and configured entirely in Python, which means you can leverage the full power and flexibility of the language to make it fit your needs.

A default configuration file is provided in the git repository. Copy it to
~/.config/qtile/config.py by executing:
$ mkdir -p ~/.config/qtile/ $ wget https://raw.github.com/qtile/qtile/develop/libqtile/resources/default_config.py -O - > ~/.config/qtile/config.py
If this fails execute the commands:
$ rm ~/.config/qtile/config.py $ cp /usr/lib/python2.7/site-packages/libqtile/resources/default_config.py ~/.config/qtile/config.py
The configuration is fully done in Python in the file
~/.config/qtile/config.py. For a very quick introduction to Python, you can read this tutorial. It will explain Python variables, functions, modules and other things you need to know to quickly get started on configuring Qtile.
Before restarting Qtile you can test your config file for syntax errors using the command:
$ python2 -m py_compile ~/.config/qtile/config.py
If the command gives no output, your script is correct.
In Qtile, the workspaces (or views) are called Groups. They can be defined as following:
from libqtile.config import Group, Match ... groups = [ Group("term"), Group("irc"), Group("web", match=Match(title=["Firefox"])), ] ...
You can configure your shortcuts with the Key class. Here is an example of the shortcut Template:Keypress to quit the window manager.
from libqtile.config import Key from libqtile.command import lazy ... keys = [ Key( ["mod1", "shift"], "q", lazy.shutdown()) ] ...
You can find out which
modX corresponds to which key with the command Xmodmap.
Screens and Bars
Create one Screen class for every monitor you have. The bars of Qtile are configured in the Screen class as in the following example:
from libqtile.config import Screen from libqtile import bar, widget ... screens = [ Screen( bottom=bar.Bar([ # add a bar to the bottom of the screen widget.GroupBox(), # display the current Group widget.WindowName() # display the name of the window that currently has focus ], 30)) ] ...
You can find a list of all the built-in widgets in the official documentation.
If you want to add a widget to your bar, just add it like in the example above (for the
WindowName widget). For example, if we want
to add a battery notification, we can use the
from libqtile.config import Screen from libqtile import bar, widget ... screens = [ Screen(top=bar.Bar([ widget.GroupBox(), # display the current Group widget.Battery() # display the battery state ], 30)) ] ...
You can start up applications using hooks, specifically the
startup hook. For a list of available hooks see the documentation.
Here is an example where an application starts only once:
import subprocess, re def is_running(process): s = subprocess.Popen(["ps", "axw"], stdout=subprocess.PIPE) for x in s.stdout: if re.search(process, x): return True return False def execute_once(process): if not is_running(process): return subprocess.Popen(process.split()) # start the applications at Qtile startup @hook.subscribe.startup def startup(): execute_once("parcellite") execute_once("nm-applet") execute_once("dropboxd") execute_once("feh --bg-scale ~/Pictures/wallpapers.jpg")
You can add shortcuts to easily control the sound volume and state by adding a user to the audio group and using the
alsamixer command-line interface.
keys= [ ... # Sound Key(, "XF86AudioMute", lazy.spawn("amixer -q set Master toggle")), Key(, "XF86AudioLowerVolume", lazy.spawn("amixer -c 0 sset Master 1- unmute")), Key(, "XF86AudioRaiseVolume", lazy.spawn("amixer -c 0 sset Master 1+ unmute")) ]
If you want to locate the source of a problem, you can execute the following line in your terminal:
echo "exec qtile" > /tmp/.start_qtile ; xinit /tmp/.start_qtile -- :2
