After some poking around it seems that the change group hook has a weird
version of the qtile object that is missing some attributes.
So I've come up with the following solution:
In your config place:
```
from libqtile import qtile #this is the correct version of the qtile
object with all attributes
bar_is_hidden = False #flip this if www is your main group
def toggle_bar(qtile):
global bar_is_hidden #I've commited a python nasty here, but
cmd_hide_show_bar() doesn't store bar state so the config has too
if qtile.current_group.name == "www" and not bar_is_hidden:
qtile.cmd_hide_show_bar("top")
bar_is_hidden = True
if qtile.current_group.name != "www" and bar_is_hidden:
qtile.cmd_hide_show_bar("top")
bar_is_hidden = False
```
Then from your group toggle keybind do something like:
```
Key([mod], "a", lazy.screen.toggle_Group(), lazy.function(toggle_bar),
desc="toggle group"),
```
note that the keybind wont work with the groups widget. you'll have to bind
a mouse callback to lazy.function(toggle_bar) if you want to use that.
also if you are using keybinds to switch to specific groups you might have
to change the logic in the toggle_bar function so that it triggers at the
appropriate times.
hope this helps. feel free to ask any questions
