Gtk.AccessibleRange

interface

An interface for accessible objects containing a numeric value.

GtkAccessibleRange 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

Virtual methods

do_set_current_value

def do_set_current_value(self, value: float) -> bool

Sets the current value of the accessible range.

This operation should behave similarly as if the user performed the action.

Parameters:

• value — the value to set
