Inherits Tp::Object.
The Contact class represents a Telepathy contact.
The accessor functions on this object (id(), alias(), and so on) don't make any D-Bus calls; instead, they return/use values cached from a previous introspection run. The introspection process populates their values in the most efficient way possible based on what the service implements.
To avoid unnecessary D-Bus traffic, some accessors only return valid information after specific features have been enabled. For instance, to retrieve the contact avatar token, it is necessary to enable the feature Contact::FeatureAvatarToken. See the individual methods descriptions for more details.
Contact features can be enabled by constructing a ContactFactory and enabling the desired features, and passing it to AccountManager, Account or ClientRegistrar when creating them as appropriate. However, if a particular feature is only ever used in a specific circumstance, such as an user opening some settings dialog separate from the general view of the application, features can be later enabled as needed by calling ContactManager::upgradeContacts() with the additional features, and waiting for the resulting PendingOperation to finish.
As an addition to accessors, signals are emitted to indicate that properties have changed, for example aliasChanged(), avatarTokenChanged(), etc.

Tp::Contact::~Contact | ( | ) |
Class destructor.
Tp::Contact::Contact | ( | ContactManager * | manager, | |
const ReferencedHandles & | handle, | |||
const Features & | requestedFeatures, | |||
const QVariantMap & | attributes | |||
) | [protected] |
Construct a new Contact object.
manager | ContactManager owning this contact. | |
handle | The contact handle. | |
requestedFeatures | The contact requested features. | |
attributes | The contact attributes. |
ContactManagerPtr Tp::Contact::manager | ( | ) | const |
Return the contact nanager owning this contact.
ReferencedHandles Tp::Contact::handle | ( | ) | const |
Return the handle of this contact.
QString Tp::Contact::id | ( | ) | const |
Return the identifier of this contact.
Features Tp::Contact::requestedFeatures | ( | ) | const |
Return the features requested on this contact.
Features Tp::Contact::actualFeatures | ( | ) | const |
Return the features that are actually enabled on this contact.
QString Tp::Contact::alias | ( | ) | const |
Return the alias of this contact.
Change notification is via the aliasChanged() signal.
This method requires Contact::FeatureAlias to be ready.
bool Tp::Contact::isAvatarTokenKnown | ( | ) | const |
Return whether the avatar token of this contact is known.
This method requires Contact::FeatureAvatarToken to be ready.
true
if the avatar token is known, false
otherwise.QString Tp::Contact::avatarToken | ( | ) | const |
Return the avatar token for this contact.
Change notification is via the avatarTokenChanged() signal.
This method requires Contact::FeatureAvatarToken to be ready.
AvatarData Tp::Contact::avatarData | ( | ) | const |
Return the actual avatar for this contact.
Change notification is via the avatarDataChanged() signal.
This method requires Contact::FeatureAvatarData to be ready.
void Tp::Contact::requestAvatarData | ( | ) |
Start a request to retrieve the avatar for this contact.
Force the request of the avatar data. This method returns directly, emitting avatarTokenChanged() and avatarDataChanged() signals once the token and data are fetched from the server.
This is only useful if the avatar token is unknown; see isAvatarTokenKnown(). It happens in the case of offline XMPP contacts, because the server does not send the token for them and an explicit request of the avatar data is needed.
This method requires Contact::FeatureAvatarData to be ready.
Presence Tp::Contact::presence | ( | ) | const |
Return the actual presence of this contact.
Change notification is via the presenceChanged() signal.
This method requires Contact::FeatureSimplePresence to be ready.
ContactCapabilities Tp::Contact::capabilities | ( | ) | const |
Return the capabilities for this contact.
User interfaces can use this information to show or hide UI components.
If ContactManager::supportedFeatures() contains Contact::FeatureCapabilities, the returned object will be a ContactCapabilities object, where CapabilitiesBase::isSpecificToContact() will be true
; if that feature isn't present, this returned object is the subset of Contact::manager()connection()capabilities() and CapabilitiesBase::isSpecificToContact() will be false
.
Change notification is via the capabilitiesChanged() signal.
This method requires Contact::FeatureCapabilities to be ready.
LocationInfo Tp::Contact::location | ( | ) | const |
Return the location for this contact.
Change notification is via the locationUpdated() signal.
This method requires Contact::FeatureLocation to be ready.
bool Tp::Contact::isContactInfoKnown | ( | ) | const |
Return whether the info card for this contact has been received.
With some protocols (notably XMPP) information is not pushed from the server and must be requested explicitely using refreshInfo() or requestInfo(). This method can be used to know if the information is received from the server or if an explicit request is needed.
This method requires Contacat::FeatureInfo to be ready.
true
if the information is known; false
otherwise.Contact::InfoFields Tp::Contact::infoFields | ( | ) | const |
Return the information for this contact.
Note that this method only return cached information. In order to refresh the information use refreshInfo().
Change notification is via the infoFieldsChanged() signal.
This method requires Contact::FeatureInfo to be ready.
PendingOperation * Tp::Contact::refreshInfo | ( | ) |
Refresh information for the given contact.
Once the information is retrieved infoFieldsChanged() will be emitted.
This method requires Contact::FeatureInfo to be ready.
PendingContactInfo * Tp::Contact::requestInfo | ( | ) |
Start a request to retrieve the information for this contact.
This method is useful for UIs that don't care about notification of changes in the contact information but want to show the contact information (e.g. right-click on a contact and show the contact info).
bool Tp::Contact::isSubscriptionStateKnown | ( | ) | const |
Return whether the presence subscription state of this contact is known.
true
if the presence subscription state is known, false
otherwise.bool Tp::Contact::isSubscriptionRejected | ( | ) | const |
Return whether a request to see this contact's presence was denied.

the a request to see the presence subscription was denied, false
otherwise.Contact::PresenceState Tp::Contact::subscriptionState | ( | ) | const |
Return the presence subscription state of this contact (i.e. whether the local user can retrieve information about this contact's presence).
bool Tp::Contact::isPublishStateKnown | ( | ) | const |
Return whether the presence publish state of this contact is known.
true
if the presence publish state is known, false
otherwise.bool Tp::Contact::isPublishCancelled | ( | ) | const |
Return whether a request to publish presence information to this contact was cancelled.
true
if a request to publish presence information was cancelled, false
otherwise.Contact::PresenceState Tp::Contact::publishState | ( | ) | const |
Return the presence publish state of this contact (i.e. whether this contact can retrieve information about the local user's presence).
QString Tp::Contact::publishStateMessage | ( | ) | const |
If the publishState() is Contact::PresenceStateAsk, return an optional message that was sent by the contact asking to receive the local user's presence; omitted if none was given.
PendingOperation * Tp::Contact::requestPresenceSubscription | ( | const QString & | message = QString() |
) |
