pub fn init()Expand description
Initializes Libhandy.
Call this function just after initializing GTK, if you are using
Gtk::Application it means it must be called when the
[startup][struct@crate::Gio::Application#startup] signal is emitted.
If Libhandy has already been initialized, the function will simply return.
This makes sure translations, types, themes, and icons for the Handy library are set up properly.
