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