/**
 * 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().
 *
 * 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 an icon name or a
 * paintable. 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.
 *
 * # CSS nodes
 *
 * |[<!-- language="plain" -->
 * entry[.flat][.warning][.error]

 * ├── image.left
 * ├── image.right
 * ├── [progress[.pulse]]
 * ]|
 *
 * GtkEntry has a main node with the name entry. Depending on the properties
 * of the entry, the style classes .read-only and .flat may appear. The style
 * classes .warning and .error may also be used with entries.
 *
 * When the entry shows icons, it adds subnodes with the name image and the
 * style class .left or .right, depending on where the icon appears.
 *
 * When the entry shows progress, it adds a subnode with the name progress.
 * The node has the style class .pulse when the shown progress is pulsing.
 *
 * For all the subnodes added to the text node in various situations,
 * see #GtkText.
