#- > use interactive;
#- > my $in = interactive->vnew;
#- > $in->ask_okcancel('title', 'question');
#- > $in->exit;
#- ask_from_ takes global options ($common):
#- title => window title
#- messages => message displayed in the upper part of the window
#- advanced_messages => message displayed when "Advanced" is pressed
#- ok => force the name of the "Ok"/"Next" button
#- cancel => force the name of the "Cancel"/"Previous" button
#- advanced_label => force the name of the "Advanced" button
#- advanced_label_close => force the name of the "Basic" button
#- advanced_state => if set to 1, force the "Advanced" part of the dialog to be opened initially
#- focus_cancel => force focus on the "Cancel" button
#- focus_first => force focus on the first entry
#- callbacks => functions called when something happen: complete canceled advanced changed focus_out ok_disabled
#- ask_from_ takes a list of entries with fields:
#- 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)
#- gtk => gtk preferences
#- type =>
#- button => (with clicked or clicked_may_quit)
#- (type defaults to button if clicked or clicked_may_quit is there)
#- (val need not be a reference) (if clicked_may_quit return true, it's as if "Ok" was pressed)
#- label => (val need not be a reference) (type defaults to label if val is not a reference)
#- bool (with "text" or "image" (which overrides text) giving an image filename)
#- range (with min, max)
#- combo (with list, not_edit, format)
#- list (with list, icon2f (aka icon), separator (aka tree), format (aka pre_format function),
#- help can be a hash or a function,
#- tree_expanded boolean telling wether the tree should be wide open by default
#- quit_if_double_click boolean
#- allow_empty_list disables the special cases for 0 and 1 element lists
#- image2f is a subroutine which takes a value of the list as parameter, and returns an array (text, image_file_name))
#- 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.
