Perl interface to the 2.x series of the GTK+ library
The Gtk2 module allows a Perl developer to use the GTK+ graphical user interface library. Find out more about GTK+ at https://gtk.org/
The GTK+ Reference Manual is also a handy companion when writing Gtk applications in any language.
The Perl bindings follow the C API very closely, and the C reference documentation should be considered the canonical source.
