Refresh ruby stack with Shoes - ruby

Question

this can be a very simple question but I have been searching for it a long time and haven't found any valid answer yet...
I am try to do a Shoes app with ruby to get a list of names and save it in a file. I would like to show the list that have been introduced already and as a new name enters the list the list which is shown would be updated. Also, I would like to associate a delete button to each element of the list so the user can remove that name if needed.
After all this, the only thing that I can get is the part in which you add a name and it gets saved into a list but adding this second stack with a list of all names with a delete button... not so lucky. This is how my code looks like, the functions addName and saveFile are not here but they only do some work with the list. Also, some global variables and constat definitions are not shown:
Shoes.app(title: "My Higgs field!",
width: APPW, height: APPH, resizable: false) {
stack{
flow{
#edit = edit_line
#enter = button "Add"
#enter.click do
info "Enter to add #{#edit.text}"
addName(#edit.text)
end
}
#save_file = button "Guardar ficheiro"
#save_file.click do
saveFile
end
}
stack do
# Show a list with all the names inserted
$names.each do |name|
flow{
#line = para name
info "Putting line #{#line}"
#delete = button "Apagar"
#delete.click do
deleteName name
end
}
end
end
}
Any inputs on this is very wellcome!
Thanks a lot!

A shoes question so long not answered ! That can't be.
Here a fully working version, i took the liberty to reorganise everything and use my favorite shoes color: green
require 'green_shoes'
Shoes.app(title: "My Higgs field!", width: 200, height: 200, resizable: false) do
#names, #list = [], nil
def update
#list.clear()
#names.each do |name|
#list.append do
flow do
para link('del'){del(name); update}, ' ', name
end
end
end
end
def add name
#names << name
#names = #names.uniq.sort
update
end
def del name
#names.delete(name)
update
end
stack do
flow do
#edit = edit_line(width: 110, height: 23)
keypress do|k|
if k == "\n"
add(#edit.text)
end
end
button "Add" do
add(#edit.text)
end
button "Save file" do
File.open("names.txt", "w+") { |file| file.write(#names.join("\n")) }
alert("names.txt is saved")
end
end
#list = flow do
#names.each do |p|
para p, :size => 10
end
end
end
end
