skin.py functions and value parsers
Search functions
Abschnitt betitelt „Search functions“Use this index to interpret XML values or locate the engine’s loading and screen-building stages. Functions run inside Enigma2; the enigma module and application state are required. Do not run global loading/reloading helpers for every widget update.
Option tokens are extracted from dictionaries and match cases in each parser. A token list does not replace the documented grammar: some tokens belong to separate subfields. See coordinates, colours and pixmaps for practical combinations.

Source snapshot: skin.py @ f4135659cb. The catalogue lists source capabilities; support also depends on the receiver build and native widget class.
InitSkins
Load emergency, subtitle, primary, display, optional skin parts and user overrides; configure desktop resolution and templates. Startup operation, not a per-widget helper.
InitSkins()loadSkin
Read one XML skin and register its global resources and named screens. Returns True on a readable parsed skin, False otherwise; does not open a screen.
loadSkin(filename, scope=SCOPE_SKINS, desktop=getDesktop(GUI_SKIN_ID), screenID=GUI_SKIN_ID)reloadSkins
Reload global skin state and window styles. This is a broad application operation, not needed for opening an isolated example.
reloadSkins()loadSkinTemplates
Load component XML template definitions from the supplied filenames.
loadSkinTemplates(skinTemplatesFileNames)reloadSkinTemplates
Rebuild component template definitions; clear=True resets previously registered definitions.
reloadSkinTemplates(clear=False)addCallback
Register a callback to be notified when skin loading invokes its callback list.
addCallback(callback)removeCallback
Remove a previously registered skin callback.
removeCallback(callback)getParentSize
Find a widget parent's size or use the desktop, for relative coordinate calculations.
getParentSize(object, desktop)skinError
Write a skin error to the Enigma2 log; does not itself raise an exception.
skinError(errorMessage)attribDeprecationWarning
Write a deprecated-attribute warning and its replacement to the log.
