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