use common qw(:common :functional);

#- ask_from_entries takes:
#-  val      => reference to the value
#-  label    => description
#-  icon     => icon to put before the description
#-  help     => tooltip
#-  advanced => wether it is shown in by default or only in advanced mode
#-  disabled => function returning wether it should be disabled (grayed)
#-  type     => 
#-     button => (with clicked) (type defaults to button if clicked is there) (val need not be a reference)
#-     label => (val need not be a reference) (type defaults to label if val is not a reference) 
#-     bool (with text)
#-     range (with min, max)
#-     combo (with list, not_edit)
#-     list (with list, icon2f (aka icon), separator (aka tree), format (aka pre_format function),
#-           help can be a hash or a function)
#-     entry (the default) (with hidden)
#
#- heritate from this class and you'll get all made interactivity for same steps.
#- for this you need to provide
#- - ask_from_listW(o, title, messages, arrayref, default) returns one string of arrayref
#-
#- where
#- - o is the object
#- - title is a string
#- - messages is an refarray of strings
#- - default is an optional string (default is in arrayref)
#- - arrayref is an arrayref of strings
#- - arrayref2 contains booleans telling the default state,
#-
#- ask_from_list and ask_from_list_ are wrappers around ask_from_biglist and ask_from_smalllist
#-
#- ask_from_list_ just translate arrayref before calling ask_from_list and untranslate the result
#-
#- ask_from_listW should handle differently small lists and big ones.
