A theme is a collection **views** that define some **elements**, each with their own **properties**. +Table of contents: -The first place ES-DE will check for a theme is in the system's `` folder, for a theme.xml file: -* `[SYSTEM_PATH]/theme.xml` +[[_TOC_]] -If that file doesn't exist, ES-DE will try to find the theme in the current **theme set**. Theme sets are just a collection of individual system themes arranged in the "themes" folder under some name.

Here's an example: +## Introduction + +ES-DE allows the grouping of themes for multiple game systems into a **theme set**. Each theme is a collection of **views** that define some **elements**, each with their own **properties**. + +Every game system has its own subdirectory within the theme set directory structure, and these are defined in the systems configuration file `es_systems.xml` either via the optional `` tag, or otherwise via the mandatory `` tag. When ES-DE populates a system on startup it will look for a file named `theme.xml` in each such directory. + +By placing a theme.xml file directly in the root of the theme set directory, that file will be processed as a default if there is no game-specific theme.xml file available. + +In the example below, we have a theme set named `mythemeset-DE` which includes the `snes` and `nes` systems. Assuming you have some games installed for these systems, the files `mythemeset-DE/nes/theme.xml` and `mythemeset-DE/snes/theme.xml` will be processed on startup. If there are no games available for a system, its theme.xml file will be skipped. + +The directory structure of our example theme set could look something like the following: ``` ... themes/ - my_theme_set/ - snes/ - theme.xml - my_cool_background.jpg + mythemeset-DE/ + core/ + font.ttf + bold_font.ttf + frame.png nes/ theme.xml - my_other_super_cool_background.jpg + background.jpg + logo.svg + logo_video.svg - common_resources/ - my_font.ttf - - theme.xml (Default theme) - another_theme_set/ snes/ theme.xml - some_resource.svg + background.jpg + logo.svg + logo_video.svg + + fonts.xml + theme.xml ``` -The theme set system makes it easy for users to try different themes and allows distributions to include multiple theme options. Users can change the currently active theme set in the "UI Settings" menu. The option is only visible if at least one theme set exists. +The theme set approach makes it easy for users to install different themes and choose between them from the _UI Settings_ menu.
