GtkAccessibleText

since: 4.14

Description [src]

interface Gtk.AccessibleText : Gtk.Accessible

An interface for accessible objects containing formatted text.

The GtkAccessibleText interfaces is meant to be implemented by accessible objects that have text formatted with attributes, or non-trivial text contents.

You should use the GTK_ACCESSIBLE_PROPERTY_LABEL or the GTK_ACCESSIBLE_PROPERTY_DESCRIPTION properties for accessible objects containing simple, unformatted text.

Available since: 4.14

Prerequisite

In order to implement AccessibleText, your type must inherit fromGtkAccessible.
