A group is a container for a bunch of windows, analogous to workspaces in other window managers. Each client window managed by the window manager belongs to exactly one group. The groups config file variable should be initialized to a list of DGroup objects.
DGroup objects provide several options for group configuration. Groups can be configured to show and hide themselves when they’re not empty, spawn applications for them when they start, automatically acquire certain groups, and various other options.
from libqtile.config import Group, Match groups = [ Group("a"), Group("b"), Group("c", match=Match(title=["Firefox"])), ] # allow mod3+1 through mod3+0 to bind to groups; if you bind your groups # by hand in your config, you don't need to do this. from libqtile.dgroups import simple_key_binder dgroups_key_binder = simple_key_binder("mod3")
