The “active-descendant-changed” signal is emitted by an object which has the state ATK_STATE_MANAGES_DESCENDANTS when the focus object in the object changes. For instance, a table will emit the signal when the cell in the table which has focus changes.

The “announcement” signal can be emitted to pass an announcement on to be read by a screen reader.

The “attribute-changed” signal should be emitted when one of an object’s attributes changes.

The signal “children-changed” is emitted when a child is added or removed from an object. It supports two details: “add” and “remove”.

The signal “focus-event” is emitted when an object gained or lost focus.

The “notification” signal can be emitted to pass an announcement on to be read by a screen reader.

The signal “property-change” is emitted when an object’s property value changes. arg1 contains an AtkPropertyValues with the name and the new value of the property whose value has changed. Note that, as with GObject notify, getting this signal does not guarantee that the value of the property has actually changed; it may also be emitted when the setter of the property is called to reinstate the previous value.

The “state-change” signal is emitted when an object’s state changes. The detail value identifies the state type which has changed.

The “visible-data-changed” signal is emitted when the visual appearance of the object changed.

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

The ‘bounds-changed” signal is emitted when the position or size of the component changes.
