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