    /// The [`Clipboard`][crate::Clipboard] object represents a clipboard of data shared
    /// between different processes or between different widgets in
    /// the same process. Each clipboard is identified by a name encoded as a
    /// [`gdk::Atom`][crate::gdk::Atom]. (Conversion to and from strings can be done with
    /// [`gdk::Atom::intern()`][crate::gdk::Atom::intern()] and [`gdk::Atom::name()`][crate::gdk::Atom::name()].) The default clipboard
    /// corresponds to the “CLIPBOARD” atom; another commonly used clipboard
    /// is the “PRIMARY” clipboard, which, in X, traditionally contains
    /// the currently selected text.
    ///
    /// To support having a number of different formats on the clipboard
    /// at the same time, the clipboard mechanism allows providing
    /// callbacks instead of the actual data. When you set the contents
    /// of the clipboard, you can either supply the data directly (via
    /// functions like [`set_text()`][Self::set_text()]), or you can supply a
    /// callback to be called at a later time when the data is needed (via
    /// `gtk_clipboard_set_with_data()` or `gtk_clipboard_set_with_owner()`.)
    /// Providing a callback also avoids having to make copies of the data
    /// when it is not needed.
    ///
    /// `gtk_clipboard_set_with_data()` and `gtk_clipboard_set_with_owner()`
    /// are quite similar; the choice between the two depends mostly on
    /// which is more convenient in a particular situation.
    /// The former is most useful when you want to have a blob of data
    /// with callbacks to convert it into the various data types that you
    /// advertise. When the `clear_func` you provided is called, you
    /// simply free the data blob. The latter is more useful when the
    /// contents of clipboard reflect the internal state of a [`glib::Object`][crate::glib::Object]
    /// (As an example, for the PRIMARY clipboard, when an entry widget
    /// provides the clipboard’s contents the contents are simply the
    /// text within the selected region.) If the contents change, the
    /// entry widget can call `gtk_clipboard_set_with_owner()` to update
    /// the timestamp for clipboard ownership, without having to worry
    /// about `clear_func` being called.
    ///
    /// Requesting the data from the clipboard is essentially
    /// asynchronous. If the contents of the clipboard are provided within
    /// the same process, then a direct function call will be made to
    /// retrieve the data, but if they are provided by another process,
    /// then the data needs to be retrieved from the other process, which
    /// may take some time. To avoid blocking the user interface, the call
    /// to request the selection, [`request_contents()`][Self::request_contents()] takes a
    /// callback that will be called when the contents are received (or
    /// when the request fails.) If you don’t want to deal with providing
    /// a separate callback, you can also use [`wait_for_contents()`][Self::wait_for_contents()].
    /// What this does is run the GLib main loop recursively waiting for
    /// the contents. This can simplify the code flow, but you still have
    /// to be aware that other callbacks in your program can be called
    /// while this recursive mainloop is running.
    ///
    /// Along with the functions to get the clipboard contents as an
    /// arbitrary data chunk, there are also functions to retrieve
    /// it as text, [`request_text()`][Self::request_text()] and
    /// [`wait_for_text()`][Self::wait_for_text()]. These functions take care of
    /// determining which formats are advertised by the clipboard
    /// provider, asking for the clipboard in the best available format
    /// and converting the results into the UTF-8 encoding. (The standard
    /// form for representing strings in GTK+.)
