Can someone help with a question about the Qtile bar?
I use several GenPollText widgets to display the output of scripts in a top
bar, like this:
screens = [
Screen(
top = bar.Bar([
widget.GenPollText(
func = qtb_1,
update_interval = 1800,
),
widget.GenPollText(
func = qtb_2,
update_interval = 600,
),
...
This works very well, but sometimes I want to update one of the values on
demand rather than wait for the poll interval (the bash scripts are
expensive). If I click on the bar widget with the mouse, the script
triggers and the value updates immediately. I'd like to achieve the same
thing with a key-press.
Looking at the GenPollText class, it seems a left click calls button_press
from InLoopPollText in libqtile.widget.base, which updates the widget
content.
How can I call button_press or, better still, whatever function actually
does the widget update, from a Key() in my config? I'm very new to Python
and I need hand-holding with how to create/call the lazy.lazy function and
have it index the correct widget.
Any help would be greatly appreciated!
A related question: I played with fake_button_press from the Bar API as a
way to update the widget from the script itself using qtile-cmd, but I
couldn't get it to work. Using qshell I tried:
> cd bar/top
bar[top] > fake_button_press(0,top,5,5,1)
This should hit button-1 at coords (5,5) from top left of screen offset 0.
Instead I got:
Command exception: Traceback (most recent call last):
File "/usr/lib/python3.8/site-packages/libqtile/command_interface.py",
line 303, in call
return SUCCESS, cmd(*args, **kwargs)

get_widget_in_position
if e.event_x < i.offsetx + i.length:
TypeError: '<' not supported between instances of 'str' and 'int'
Casting with int() just gives 'Invalid command:'
Using qtile-cmd:
$ qtile-cmd -o bar top -f fake_button_press -a 0 top 5 5 1
error: Sorry cannot run function 'fake_button_press' with arguments ['0',
'top', '5', '5', '1']
Any idea what I'm doing wrong here?
Thanks.
