-/**
- * SECTION:gtkclipboard
- * @Short_description: Storing data on clipboards
- * @Title: Clipboards
- * @See_also: #GtkSelectionData
- *
- * The #GtkClipboard 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
- * #GdkAtom. (Conversion to and from strings can be done with
- * gdk_atom_intern() and 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 gtk_clipboard_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 #GObject
- * (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, gtk_clipboard_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 gtk_clipboard_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, gtk_clipboard_request_text() and
- * gtk_clipboard_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+.)
