Struct ActiveDescendantChangedEvent 

pub struct ActiveDescendantChangedEvent {
    pub item: ObjectRefOwned,
    pub descendant: ObjectRefOwned,
}

An event fired when the focus has moved within a tree. The parent: item and descendant (may not be a direct child): descebdant are both referenced for convenience.

Fields

item: ObjectRefOwned

The crate::ObjectRef which the event applies to.

descendant: ObjectRefOwned

The descendant which is now the active one.

The body of the object.

impl<'msg> MessageConversionExt<'msg, EventBody<'msg>> for ActiveDescendantChangedEvent

fn try_from_message( msg: &'msg Message, header: &Header<'_>, ) -> Result<ActiveDescendantChangedEvent, AtspiError>

Convert a zbus::Message into this event type. Does all the validation for you.

fn validate_interface(header: &Header<'_>) -> Result<(), AtspiError>

Validate the interface string via zbus::message::Header::interface against Self’s assignment of DBusInterface::DBUS_INTERFACE

fn validate_member(hdr: &Header<'_>) -> Result<(), AtspiError>

fn eq(&self, other: &ActiveDescendantChangedEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
