;; HERE BE DRAGONS ;;
;;;;;;;;;;;;;;;;;;;;;
;; This software requires a patch to be applied to the Sawfish source to
;; add some additional XLib bindings.
;; Please see x.c.patch.
;;;;;;;;;;;;;;;;;;
;; INSTALLATION ;;
;;;;;;;;;;;;;;;;;;
;; Create a directory ~/.sawfish/lisp/merlin and then put this file there:
;; mkdir -p ~/.sawfish/lisp/merlin
;; mv iconbox.jl ~/.sawfish/lisp/merlin
;; You also need merlin/sawlet.jl, merlin/util.jl and merlin/x-util.jl.
;; You're probably best off unpacking the entire merlin.tgz archive.
;; Then add to your .sawfishrc:
;; (require 'merlin.iconbox)
;; (deficonbox iconbox)
;; Then restart sawfish. An icon box should appear in the top right corner
;; of your screen.
;; Go to Customize->Sawlets->Iconbox
;; - Here you can customize the behaviour of the icon box
;; Also go to Customize->Matched Windows->^Sawlet/iconbox$->Edit...
;; - Here you can specify a border type for the window, etc.
;; You can create multiple icon boxes and can configure them programatically
;; at creation if you want.. but you probably don't..
;;;;;;;;;;;;;;;;;;
;; HERE BE BUGS ;;
;;;;;;;;;;;;;;;;;;
;; TODO: Orientation, ... hover delay ..., tooltips, ... use icon name
;; TODO: only display windows iconified on current viewport/workspace.
;; TODO: support dragging into iconbox?
; BUG: I don't understand why, but if you click then drag a fraction
; (preferably, but not necessarily to outside of the icon) then wait
; a while then containue the drag, nothing happens. but if you
; only wait a short while before continuing then it works.
; I don't get the events??
; Events are lost. But it is not me (I think).
