+ * @Short_description: Interface for text-editing widgets
+ * @Title: GtkEditable
+ *
+ * The #GtkEditable interface is an interface which should be implemented by
+ * text editing widgets, such as #GtkEntry and #GtkSpinButton. It contains functions
+ * for generically manipulating an editable widget, a large number of action
+ * signals used for key bindings, and several signals that an application can
+ * connect to to modify the behavior of a widget.
+ *
+ * As an example of the latter usage, by connecting
+ * the following handler to #GtkEditable::insert-text, an application
+ * can convert all entry into a widget into uppercase.
+ *
+ * <example>
+ * <title>Forcing entry to uppercase.</title>
+ * <programlisting>
+ * #include <ctype.h>
+ *
+ * void
+ * insert_text_handler (GtkEditable *editable,
+ * const gchar *text,
+ * gint length,
+ * gint *position,
+ * gpointer data)
+ * {
+ * gchar *result = g_utf8_strup (text, length);
+ *
+ * g_signal_handlers_block_by_func (editable,
+ * (gpointer) insert_text_handler, data);
+ * gtk_editable_insert_text (editable, result, length, position);
+ * g_signal_handlers_unblock_by_func (editable,
+ * (gpointer) insert_text_handler, data);
