48// An interface for accessible objects containing a numeric value.
49//
50// `GtkAccessibleRange` describes ranged controls for Assistive Technologies.
51//
52// Ranged controls have a single value within an allowed range that can
53// optionally be changed by the user.
54//
55// This interface is expected to be implemented by controls using the
56// following roles:
57//
58// - `GTK_ACCESSIBLE_ROLE_METER`
59// - `GTK_ACCESSIBLE_ROLE_PROGRESS_BAR`
60// - `GTK_ACCESSIBLE_ROLE_SCROLLBAR`
61// - `GTK_ACCESSIBLE_ROLE_SLIDER`
62// - `GTK_ACCESSIBLE_ROLE_SPIN_BUTTON`
63//
64// If that is not the case, a warning will be issued at run time.
65//
66// In addition to this interface, its implementers are expected to provide the
67// correct values for the following properties:
68//
69// - `GTK_ACCESSIBLE_PROPERTY_VALUE_MAX`
70// - `GTK_ACCESSIBLE_PROPERTY_VALUE_MIN`
71// - `GTK_ACCESSIBLE_PROPERTY_VALUE_NOW`
72// - `GTK_ACCESSIBLE_PROPERTY_VALUE_TEXT`
