Changing image in a launcher button

[Emilio J. Padron]

Hi all,

may I change (dynamically) the image associated with a launcher?

I have defined a button for launching alsamixergui and I would like it
shows the mute/non_mute state with its icon. The launcher is defined
this way:

--
mixerlauncher = awful.widget.launcher({ 
                                        image = 
".config/awesome/icons_dzen/vol-hi.png",
                                        command = mixer,
                                        align ="right" })
--

and I'm trying something like this in a timer hook:

--
awful.hooks.timer.register(4, function ()
    vol = amixer_volume()
    if vol = "---" then
      mixerlauncher.image = ".config/awesome/icons_dzen/vol-mute.png"
    else
      mixerlauncher.image = ".config/awesome/icons_dzen/vol-hi.png"
    end
    volumewidget.text = " " .. vol .. " "
end)
--

I have also tried (with no success) something like:

--
      mixerlauncher.image = image(".config/awesome/icons_dzen/vol-mute.png")
--

Thanks in advance :-)

Emilio
