How the clipboard works

Read Original

This article demystifies how the clipboard (selection) works in the Wayland display server protocol. It details the process where copying announces data availability, not actual data transfer, and pasting involves requesting data via file descriptors. It covers MIME types, ownership transfer, and the roles of wl_data_source and wl_data_device.
