* The #HildonEntry is text entry derived from the #GtkEntry widget providing
* additional commodities specific to the Hildon framework.
*
- * Besides all the features inherited from #GtkEntry, a #HildonEntry
- * can also have a placeholder text. This text will be shown if the
- * entry is empty and doesn't have the input focus, but it's otherwise
- * ignored. Thus, calls to hildon_entry_get_text() will never return
- * the placeholder text, not even when it's being displayed.
- *
- * Although #HildonEntry is derived from #GtkEntry,
- * gtk_entry_get_text() and gtk_entry_set_text() must never be used to
- * get/set the text in this widget. hildon_entry_get_text() and
- * hildon_entry_set_text() must be used instead.
+ * A #HildonEntry can have a placeholder text. This text will be shown
