add unfocus signal to a particular client

[Anurag Priyam]

Hi,

I am trying to emulate tilda's( drop down terminal ) behaviour :
automatically disappear when the user switches to some other application. I
want this behavior for a couple of apps like : gmpc, shell, thunar, hence
the effort.

Here is what I am doing:

Add a unfocus signal to the particular client using rules and callbacks.

    { rule = { class = "Thunar" },
      properties = { floating = true },
      callback = function(c)
          set_geometry()
          c:add_signal("unfocus", function(c)
              hide(c)
          end)
      end
    },

hide function is accessible and contains the following code( it works ):

local function hide(c)
    print("hiding")  -- debug
    c.hidden = true
    local ctags = c:tags()
    for i, t in pairs(ctags) do
        ctags[i] = nil
    end
    c:tags(ctags)
    return
end

I find that the hide function is never called. .xsession-errors neither
reports an error nor prints "hiding" message.
