- Lighthouse is a Qt port
- There is a Plugin API for backends
Lighthouse itself is completely windowsystem agnostic. In contrast to QWS, it does not even care if it’s running as a single process, or whether there are multiple Lighthouse processes on the system. All Lighthouse knows is that there is a way to create window surfaces. How these surfaces are shown on the display is up to the backend. In a multi-process setting where a client process needs to communicate with a server to show something on the screen, the inter-process communication will be handled by the backend.
