Description
GTK3 applications can share custom interface widgets instead of each project implementing the same controls again.
This package is useful for software that was written against the libsexy3 widget set. It does not add a separate app; it supplies reusable GTK3 components used by another program at runtime or by developers while building desktop interfaces.
Install it when a GTK3 application lists it as a dependency. People creating new interfaces should usually choose maintained GTK3 or GTK4 APIs when possible.
