Generally this should only be called between the time you call gtk_clipboard_set_with_owner() or gtk_clipboard_set_with_data(), and when the clear_func you supplied is called. Otherwise, the clipboard may be owned by someone else. Glib::RefPtr<Clipboard> Gtk::Clipboard::get ( GdkAtom    selection = GDK_SELECTION_CLIPBOARD )  [static]   Returns the clipboard object for the given selection. See gtk_clipboard_get_for_display() for complete details. Parameters: selection  A Gdk::Atom which identifies the clipboard to use. Returns: The appropriate clipboard object. If no clipboard already exists, a new one will be created. Once a clipboard object has been created, it is persistent for all time and cannot be freed. Glib::RefPtr<const Gdk::Display> Gtk::Clipboard::get_display (   )  const   Gets the Gdk::Display associated with clipboard. Returns: The Gdk::Display associated with clipboard Since: 2.2. Glib::RefPtr<Gdk::Display> Gtk::Clipboard::get_display (   )    Gets the Gdk::Display associated with clipboard. Returns: The Gdk::Display associated with clipboard Since: 2.2. Glib::RefPtr<Clipboard> Gtk::Clipboard::get_for_display ( const Glib::RefPtr<Gdk::Display>&    display, GdkAtom    selection = GDK_SELECTION_CLIPBOARD )  [static]   Returns the clipboard object for the given selection. Cut/copy/paste menu items and keyboard shortcuts should use the default clipboard, returned by passing Gdk::SELECTION_CLIPBOARD for selection . (Gdk::NONE is supported as a synonym for GDK_SELECTION_CLIPBOARD for backwards compatibility reasons.) The currently-selected object or text should be provided on the clipboard identified by Gdk::SELECTION_PRIMARY. Cut/copy/paste menu items conceptually copy the contents of the Gdk::SELECTION_PRIMARY clipboard to the default clipboard, i.e. they copy the selection to what the user sees as the clipboard. (Passing Gdk::NONE is the same as using gdk_atom_intern ("CLIPBOARD", false). See http://www.freedesktop.org/standards/clipboards.txt for a detailed discussion of the "CLIPBOARD" vs. "PRIMARY" selections under the X window system. On Win32 the Gdk::SELECTION_PRIMARY clipboard is essentially ignored.) It's possible to have arbitrary named clipboards; if you do invent new clipboards, you should prefix the selection name with an underscore (because the ICCCM requires that nonstandard atoms are underscore-prefixed), and namespace it as well. For example, if your application called "Foo" has a special-purpose clipboard, you might call it "_FOO_SPECIAL_CLIPBOARD". Parameters: display  The display for which the clipboard is to be retrieved or created. selection  A Gdk::Atom which identifies the clipboard to use. Returns: The appropriate clipboard object. If no clipboard already exists, a new one will be created. Once a clipboard object has been created, it is persistent for all time and cannot be freed. Since: 2.2. Glib::RefPtr<const Glib::Object> Gtk::Clipboard::get_owner (   )  const   If the clipboard contents callbacks were set with gtk_clipboard_set_with_owner(), and the gtk_clipboard_set_with_data() or gtk_clipboard_clear() has not subsequently called, returns the owner set by gtk_clipboard_set_with_owner(). Returns: The owner of the clipboard, if any; otherwise 0. Glib::RefPtr<Glib::Object> Gtk::Clipboard::get_owner (   )    If the clipboard contents callbacks were set with gtk_clipboard_set_with_owner(), and the gtk_clipboard_set_with_data() or gtk_clipboard_clear() has not subsequently called, returns the owner set by gtk_clipboard_set_with_owner(). Returns: The owner of the clipboard, if any; otherwise 0. const GtkClipboard* Gtk::Clipboard::gobj (   )  const [inline]   Reimplemented from Glib::ObjectBase. GtkClipboard* Gtk::Clipboard::gobj (   )  [inline]   Reimplemented from Glib::ObjectBase. GtkClipboard* Gtk::Clipboard::gobj_copy (   )  void Gtk::Clipboard::request_contents ( const Glib::ustring&    target, const SlotReceived&    slot )  void Gtk::Clipboard::request_targets ( const SlotReceived&    slot )  void Gtk::Clipboard::request_text ( const SlotTextReceived&    slot )  bool Gtk::Clipboard::set ( const ArrayHandle_TargetEntry&    targets, const SlotGet&    slot_get, const SlotClear&    slot_clear )    Virtually sets the contents of the specified clipboard by providing a list of supported formats for the clipboard data and a function to call to get the actual data when it is requested. Parameters: targets  Information about the available forms for the clipboard data. slot_get  method to call to get the actual clipboard data. slot_clear  When the clipboard contents are set again, this method will be called, and slot_get will not be subsequently called. Returns: true if setting the clipboard data succeeded. If setting the clipboard data failed then the provided callback methods will be ignored. void Gtk::Clipboard::set_text ( const Glib::ustring&    text )    Sets the contents of the clipboard to the given UTF-8 string. GTK+ will make a copy of the text and take responsibility for responding for requests for the text, and for converting the text into the requested format. Parameters: text  A UTF-8 string. SelectionData Gtk::Clipboard::wait_for_contents ( const Glib::ustring&    target )  const   Requests the contents of the clipboard using the given target. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait. Parameters: target  The form into which the clipboard owner should convert the selection. Returns: A GtkSelectionData object, which will be invalid if retrieving the given target failed. Glib::ustring Gtk::Clipboard::wait_for_text (   )  const   Requests the contents of the clipboard as text and converts the result to UTF-8 if necessary. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait. Returns: A newly-allocated UTF-8 string which must be freed with Glib::free(), or 0 if retrieving the selection data failed. (This could happen for various reasons, in particular if the clipboard was empty or if the contents of the clipboard could not be converted into text form.). bool Gtk::Clipboard::wait_is_text_available (   )  const   Test to see if there is text available to be pasted This is done by requesting the TARGETS atom and checking if it contains any of the names: STRING, TEXT, COMPOUND_TEXT, UTF8_STRING. This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait. This function is a little faster than calling gtk_clipboard_wait_for_text() since it doesn't need to retrieve the actual text. Returns: true is there is text available, false otherwise.
