//ui/base

This directory contains low-level code that is reused throughout the chromium UI stack. Code in this directory can't depend on most of the rest of //ui (with a few exceptions), and code throughout the rest of //ui can depend on it.

Toolkit-specific libraries in this directory include:

  • cocoa: for working with Cocoa on macOS
  • wayland: for Linux systems with Wayland
  • webui: for WebUI in Chromium
  • win: for Windows systems
  • x: for Linux systems with X11

Platform-independent libraries in this directory include:

  • l10n: localization APIs used throughout all of chromium, especially the widely-used l10n_util::GetString* functions
  • metadata: the implementation of the property/metadata system used throughout views
  • models: toolkit-agnostic types used to represent the data shown in UI controls and dialogs
  • resource: resource bundle APIs, which are used for retrieving icons and raw localized strings from the app package

As with most “base” libraries this is somewhat of a dumping ground of code that is used in a bunch of other places, and there‘s no hard and fast rule to tell what should or shouldn’t be in here. If in doubt, consult with the owners.
