GenPollText has no attribute tick

[Shubham Pawar]

Hi devs, I working on qtile bar to update only on keypress. For this I followed this conversation from Jan last year but it doesn't work anymore.

This is my lazy function

@lz.function
def update_brightness(qtile):
    """Update the brightnesswidget on keypress

    Args:
        qtile (libqtile.qtile): By default passed by lz.function
    """
    w = qtile.widgets_map["backlight"]
    widgets = ",".join(qtile.widgets_map)
    logger.warn("widget names = " + widgets)
    w.tick()

Then in keys array I have

    Key(
        "<XF86MonBrightnessUp>",
        lazy.spawn("brightnessctl set +10"),
        update_brightness(),
        desc="Inc Brightness",
    ),

And finally this is my widget

                widget.GenPollText(
                    name="backlight",
                    func=lambda: subprocess.run(
                        ["brightnessctl", "g"], stdout=subprocess.PIPE
                    )
                    .stdout.decode("utf-8")
                    .strip(),
                ),

Output of log:
