Part I. API Reference: gtk-layer-shell Reference Manual

# Part I. API Reference

Gtk-layer-shell is a library to write GTK applications that use Layer Shell. Layer Shell is a Wayland protocol for desktop shell components, such as panels, notifications and wallpapers. You can use it to anchor your windows to a corner or edge of the output, or stretch them across the entire output.

This library only makes sense on Wayland compositors that support Layer Shell, and will not work on X11. It supports all Layer Shell features including popups and popovers (GTK popups Just Work™). Please open issues for any bugs you come across.
