AwesomeWM volume widget is not recognizing input

Question

Hi, I am trying to get this volume widget to work:
-- Volume widget
volumecfg = {}
volumecfg.cardid = 0
volumecfg.channel = "Master"
volumecfg.widget = widget({ type = "textbox", name = "volumecfg.widget", align = "right" })
volumecfg_t = awful.tooltip({ objects = { volumecfg.widget },})
volumecfg_t:set_text("Volume")
-- command must start with a space!
volumecfg.mixercommand = function (command)
local fd = io.popen("amixer -c " .. volumecfg.cardid .. command)
local status = fd:read("*all")
fd:close()
local volume = string.match(status, "(%d?%d?%d)%%")
volume = string.format("% 3d", volume)
status = string.match(status, "%[(o[^%]]*)%]")
if string.find(status, "on", 1, true) then
volume = volume .. "%"
else
volume = volume .. "M"
end
volumecfg.widget.text = volume
end
volumecfg.update = function ()
volumecfg.mixercommand(" sget " .. volumecfg.channel)
end
volumecfg.up = function ()
volumecfg.mixercommand(" sset " .. volumecfg.channel .. " 1%+")
end
volumecfg.down = function ()
volumecfg.mixercommand(" sset " .. volumecfg.channel .. " 1%-")
end
volumecfg.toggle = function ()
volumecfg.mixercommand(" sset " .. volumecfg.channel .. " toggle")
end
volumecfg.widget:buttons({
button({ }, 4, function () volumecfg.up() end),
button({ }, 5, function () volumecfg.down() end),
button({ }, 1, function () volumecfg.toggle() end)
volumecfg.update()
It shows up in the task bar, but I can not interact with it in any way, apart from the text box that pops up on hover. I have other widgets that accept mouse input just fine.
Anyone know what the problem might be?
UPDATE:
I set global keybindings pointing to the functions in the widget as an experiment:
awful.key({ modkey, }, "0", function () volumecfg.up() end),
awful.key({ modkey, }, "9", function () volumecfg.down() end),
And it works! So the widget is functional, it's just the mouse interaction that is broken.
When I reload awesome I get this in the console:
/home/zypo/.config/awesome/rc.lua:185: W: luaA_button_new: This function is deprecated and will be removed, see new syntax
/home/zypo/.config/awesome/rc.lua:186: W: luaA_button_new: This function is deprecated and will be removed, see new syntax
/home/zypo/.config/awesome/rc.lua:187: W: luaA_button_new: This function is deprecated and will be removed, see new syntax
those lines are:
button({ }, 4, function () volumecfg.up() end),
button({ }, 5, function () volumecfg.down() end),
button({ }, 1, function () volumecfg.toggle() end)

Hi, in order to get rid of those warnings, you can try :
volumecfg.widget:buttons({awful.util.table.join(
awful.button({ }, 4, function () volumecfg.up() end),
awful.button({ }, 5, function () volumecfg.down() end),
awful.button({ }, 1, function () volumecfg.toggle() end)
instead of :
volumecfg.widget:buttons({
button({ }, 4, function () volumecfg.up() end),
button({ }, 5, function () volumecfg.down() end),
button({ }, 1, function () volumecfg.toggle() end)
