use common;
use do_pkgs;

#- minimal example using interactive:
#
#- > use lib qw(/usr/lib/libDrakX);
#- > 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
#-  ok                   => force the name of the "Ok"/"Next" button
#-  cancel               => force the name of the "Cancel"/"Previous" button
#-  focus_cancel         => force focus on the "Cancel" button
#-  focus_first          => (deprecated) force focus on the first entry
#-  ok_disabled          => function returning wether {ok} should be disabled (grayed)
#-  validate             => function called when {ok} is pressed. If it returns false, the first entry is focused, otherwise it quits
#-  advanced             => (deprecated) function called when the "advanced" expander is toggled
#-  advanced_messages    => (deprecated) message displayed when "Advanced" is pressed
#-  advanced_label       => (deprecated) force the name of the "Advanced" button
#-  advanced_label_close => (deprecated) force the name of the "Basic" button
#-  advanced_state       => (deprecated) if set to 1, force the "Advanced" part of the dialog to be opened initially
#-  callbacks            => (deprecated) functions called when something happen: complete advanced ok_disabled

#- ask_from_ takes a list of entries with fields:
#-  val      => reference to the value
#-  label    => description
#-  title    => a boolean: whether the label should be displayed as a title (see GNOME's HIG)
#-  icon     => icon to put before the description
#-  help     => tooltip
#-  advanced => (deprecated) wether it is shown in by default or only in advanced mode
#-  focus_out => function called when the entry is focused out
#-  changed  => function called when the entry is modified
#-  validate => function called when "Ok" is pressed. If it returns false, this entry is focused, otherwise it quits
#-  disabled => function returning wether it should be disabled (grayed)
#-  focus    => function returning wether it should be focused
#-  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, SpinButton)
#-     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 image_file_name
#-     entry (the default) (with hidden)
#-     expander (with text, expanded, message, children(a list of sub entries))
#
#- 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.
