Fixes part of #41237

2003-12-16  Rodrigo Moya <rodrigo@ximian.com>

	Fixes part of #41237

	* gui/e-calendar-table.c: use GtkClipboard instead of GtkInvisible
	for cut/copy/paste.
	(selection_clear_event, selection_received, selection_get): removed
	unneeded functions.
	(e_calendar_table_init): don't create the invisible widget.
	(e_calendar_table_copy_clipboard): use gtk_clipboard_set_text().
	(e_calendar_table_paste_clipboard): use gtk_clipboard_request_text().
	(clipboard_get_text_cb): callback for gtk_clipboard_request_text().

	* gui/e-cal-view.c (e_calendar_view_init, e_calendar_view_destroy,
	e_calendar_view_copy_clipboard): no need anymore to keep the last
	clipboard selection, GtkClipboard does it for us.
