An edit_box works exactly the same as an edit_line, with one slight difference. An edit_box allows you to edit multiple lines, whereas an edit_line only allows you to edit a single line. Using only an edit_line, edit_box and two buttons, you can make a crude text editor.
Shoes.app :width => 400, :height => 300 do
flow do
@e = edit_line :width => -50
button "Load", :width => 50 do
@box.text = File.read( @e.text )
end
end
stack do
@box = edit_box :width => '100%', :height => 230
button "Save", :width => '100%' do
File.open( @e.text, 'w+' ) do|f|
f.write @box.text
end
end
end
end
