Class Details

class Gtk.AccessibleRange

Bases:

GObject.GInterface

Structure:

Gtk.AccessibleRangeInterface

This interface describes ranged controls, e.g. controls which have a single value within an allowed range and 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 implementors 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

New in version 4.10.
