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.
Install one of the following packages:
- for the latest official release, running on Python 3.
- AUR for the latest git commit, running on Python 3.
qtile start with xinit.
The default configuration includes the shortcut
Super+Enter to open a new xterm terminal, and
Super+Ctrl+q to quit Qtile.
As described in Configuration Lookup, Qtile provides a default configuration file that will be used in absence of user-defined ones. In order to start customizing Qtile, copy it to
$ mkdir -p ~/.config/qtile/ $ cp /usr/share/doc/<qtile_dir>/default_config.py ~/.config/qtile/config.py
qtile_dir is the name of the package you installed.
Alternatively, the most recent default configuration file can be downloaded from the git repository at libqtile/resources/default_config.py.
Several more complete configuration file examples can be found in the qtile-examples repository.
The configuration is fully done in Python: for a very quick introduction to the language you can read this tutorial.
Before restarting Qtile you can test your configuration 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
Alt+Shift+q 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.
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")) ]
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)) ] ...
Bars and widgets
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 os import subprocess from libqtile import hook @hook.subscribe.startup_once def autostart(): home = os.path.expanduser('~') subprocess.Popen([home + '/.config/qtile/autostart.sh'])
If you want to locate the source of a problem, you can execute the following line in your terminal:
echo "exec qtile start" > /tmp/.start_qtile ; xinit /tmp/.start_qtile -- :2
