Merge lp:~doctormo/screenlets/options-rework into lp:screenlets

[Martin Owens]

Reattempt to get merged in updated options. These are API compatible and offer a new colour array option.

[Märt Põder (boamaod)]

It seems to function generally, but acts a bit differently from the old one. For example text option does not save multiline text (probably it needs to be escaped). If nobody is against it, I think the code should be merged if Martin is willing to work on the code and fix bugs when they appear...

-# Options-system (c) RYX (aka Rico Pfaus) 2007 <[e-mail]>
-#
-# INFO:
-# - a dynamic Options-system that allows very easy creation of
-#   objects with embedded configuration-system.
-#   NOTE: The Dialog is not very nice yet - it is not good OOP-practice
-#   because too big functions and bad class-layout ... but it works
-#   for now ... :)
-#
-# TODO:
-# - option-widgets for all option-types (e.g. ListOptionWidget, ColorOptionWidget)
-# - OptionGroup-class instead of (or behind) add_options_group
-# - TimeOption, DateOption
-# - FileOption needs filter/limit-attribute
-# - allow options to disable/enable other options
-# - support for EditableOptions-subclasses as options
-# - separate OptionEditorWidget from Editor-Dialog
-# - place ui-code into screenlets.options.ui-module
-# - create own widgets for each Option-subclass

+# Options-system (c) RYX (aka Rico Pfaus) 2007 <[e-mail]>
+# Heavily Refactored by Martin Owens (c) 2009
+#
+# INFO:
+# - a dynamic Options-system that allows very easy creation of
+#   objects with embedded configuration-system.
+#   NOTE: The Dialog is not very nice yet - it is not good OOP-practice
+#   because too big functions and bad class-layout ... but it works
+#   for now ... :)
+#
+# TODO:
+# - option-widgets for all option-types (e.g. ListOptionWidget, ColorOptionWidget)
+# - OptionGroup-class instead of (or behind) add_options_group
+# - TimeOption, DateOption
+# - FileOption needs filter/limit-attribute
+# - allow options to disable/enable other options
+# - support for EditableOptions-subclasses as options
+# - separate OptionEditorWidget from Editor-Dialog
+# - place ui-code into screenlets.options.ui-module
+# - create own widgets for each Option-subclass
