module Gtk::AccessibleRange

Overview

An interface for accessible objects containing a numeric value.

Gtk::AccessibleRange describes ranged controls for Assistive Technologies.

Ranged controls have a single value within an allowed range that can optionally be changed by the user.

This interface is expected to be implemented by controls using the following roles:

• GTK_ACCESSIBLE_ROLE_METER
• GTK_ACCESSIBLE_ROLE_PROGRESS_BAR
• GTK_ACCESSIBLE_ROLE_SCROLLBAR
• GTK_ACCESSIBLE_ROLE_SLIDER
• GTK_ACCESSIBLE_ROLE_SPIN_BUTTON

If that is not the case, a warning will be issued at run time.

In addition to this interface, its implementers are expected to provide the correct values for the following properties:

• GTK_ACCESSIBLE_PROPERTY_VALUE_MAX
• GTK_ACCESSIBLE_PROPERTY_VALUE_MIN
• GTK_ACCESSIBLE_PROPERTY_VALUE_NOW
• GTK_ACCESSIBLE_PROPERTY_VALUE_TEXT

Direct including types

• Gtk::LevelBar

• Gtk::ProgressBar
• Gtk::Range

• Gtk::SpinButton
• Gtk::VolumeButton
