Hi,

I am writting a little script for displaying a list of icons and when i  
clic on one of the icon it should return the absolute path of the icon.

So i create a windows widget which contain a table widget. In each cell  
of the table I put an icon and create an event with this code:

#for a in 0…( @my\_icons\_files\_array.length - 1)

# my\_widget =Gtk::Image.new(@my\_icons\_files\_array[a])

# event\_box[a] = Gtk::EventBox.new.add(my\_widget)

# event\_box[a].signal\_connect(“button\_press\_event”) do

# …

# 

# end

# table.attach(event\_box[a],col\_begin,( col\_begin + 1 ), row\_begin,

(row\_begin + 1 ))  
#end

Is there a way to get a reference of the objet I have cliqued on in  
order to link this reference with the path used in Gtk::Image.new

Thanks

hi Silkmoth -

i answered you in the main ruby post, and suggested that you post here

- though i see you already found it! sorry 😉

############  
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

hope that helps…
