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+.) - */ - - -enum { - OWNER_CHANGE, - LAST_SIGNAL -}; - -typedef struct _RequestContentsInfo RequestContentsInfo; -typedef struct _RequestTextInfo RequestTextInfo;
