A theme element selector selects the theme element or definition to apply to an interface element. It can appear in several forms, including the following examples:
The text next to the selector indicates the type of theme element required for that interface element. This is also the theme element used by default, if no other element is selected or if the selected element is unavailable in the current theme.
The selector proposes only the theme elements adapted to the interface element according to the required type, with two variants:
If the type is of the form [definition] / [element], the selector proposes the adapted elements, as well as all the elements of the definition "custom". It should then be ensured that the selected element provides the necessary (resource and / or write font) for the concerned interface element.
If the type is of the form [definition], the selector proposes only the adapted elements, which are the default element as well as the copies of it, to ensure the presence of all necessary elements.
