hi Silkmoth,

  i use gtk2 quite a bit, and have found that the "Gnome 2" section of
this forum (under "Misc" on the top right,) is extremely helpful - and
is probably a better place to post questions about gtk2.

  in answer to your question - you could try something like this, which
will give you the filename of the file within the event box you click
on.  i've used images in my example rather than icons, but you should
get the idea....

######
require 'gtk2'

win = Gtk::Window.new()

@table  = Gtk::Table.new(0, 0, false)
@left = -1
@top = 0

img0 = Gtk::Image.new("konichiwa.jpeg") #change these, obviously
img1 = Gtk::Image.new("ride.png")
img2 = Gtk::Image.new("TradyBlix.png")
img3 = Gtk::Image.new("arm.png")

my_imgs = [img0, img1, img2, img3]

my_imgs.collect{|img|
  ebox = Gtk::EventBox.new()
  ebox.add(img)
  ebox.signal_connect("button_press_event"){p img.file} #or something
more interesting
  @left = @left + 1
  @top = @top + 1 if @left == 2 #change this,
  @left = 0 if @left == 2 #and this, to define the number of columns in
your table
  @right = @left + 1
  @bottom = @top + 1
  @table.resize(@right, @bottom)
  @table.attach_defaults(ebox, @left, @right, @top, @bottom)
}

win.add @table
win.show_all
win.signal_connect("destroy"){Gtk.main_quit}

Gtk.main
##############
