Backend implementation details

Although Toga is a cross-platform toolkit, it is sometimes necessary to invoke platform-specific logic. These guides provide information on how platform-specific features map onto the Toga backend API.

Accessing these APIs will result in an application that is no longer cross-platform (unless you gate the usage of these APIs with sys.platform or toga.platform.current_platform checks); however, accessing a backend API may be the only way to implement a feature that Toga doesn’t provide.

For details on how to access the the backend implementations, see the documentation on Toga’s three-layer architecture.
