  75  * SECTION:gtkentry
  76  * @Short_description: A single line text entry field
  77  * @Title: GtkEntry
  78  * @See_also: #GtkTextView, #GtkEntryCompletion
  79  *
  80  * The #GtkEntry widget is a single line text entry
  81  * widget. A fairly large set of key bindings are supported
  82  * by default. If the entered text is longer than the allocation
  83  * of the widget, the widget will scroll so that the cursor
  84  * position is visible.
  85  *
  86  * When using an entry for passwords and other sensitive information,
  87  * it can be put into "password mode" using gtk_entry_set_visibility().
  88  * In this mode, entered text is displayed using a 'invisible' character.
  89  * By default, GTK+ picks the best invisible character that is available
  90  * in the current font, but it can be changed with
  91  * gtk_entry_set_invisible_char(). Since 2.16, GTK+ displays a warning
  92  * when Caps Lock or input methods might interfere with entering text in
  93  * a password entry. The warning can be turned off with the
  94  * #GtkEntry:caps-lock-warning property.
  95  *
  96  * Since 2.16, GtkEntry has the ability to display progress or activity
  97  * information behind the text. To make an entry display such information,
  98  * use gtk_entry_set_progress_fraction() or gtk_entry_set_progress_pulse_step().
  99  *
 100  * Additionally, GtkEntry can show icons at either side of the entry. These
 101  * icons can be activatable by clicking, can be set up as drag source and
 102  * can have tooltips. To add an icon, use gtk_entry_set_icon_from_gicon() or
 103  * one of the various other functions that set an icon from a stock id, an
 104  * icon name or a pixbuf. To trigger an action when the user clicks an icon,
 105  * connect to the #GtkEntry::icon-press signal. To allow DND operations
 106  * from an icon, use gtk_entry_set_icon_drag_source(). To set a tooltip on
 107  * an icon, use gtk_entry_set_icon_tooltip_text() or the corresponding function
 108  * for markup.
 109  *
 110  * Note that functionality or information that is only available by clicking
 111  * on an icon in an entry may not be accessible at all to users which are not
 112  * able to use a mouse or other pointing device. It is therefore recommended
 113  * that any such functionality should also be available by other means, e.g.
 114  * via the context menu of the entry.
