For more details, please refer to Telepathy specification.

See Asynchronous Object Model, Shared Pointer Usage

Constructor & Destructor Documentation

Tp::TextChannel::~TextChannel ( )
virtual

Class destructor.

Tp::TextChannel::TextChannel ( const ConnectionPtr &  connection,
const QString &  objectPath,
const QVariantMap &  immutableProperties,
const Feature coreFeature = TextChannel::FeatureCore 
)
protected

Construct a new TextChannel object.

Parameters
connectionConnection owning this channel, and specifying the service.
objectPathThe channel object path.
immutablePropertiesThe channel immutable properties.
coreFeatureThe core feature of the channel type, if any. The corresponding introspectable should depend on TextChannel::FeatureCore.

Member Function Documentation

TextChannelPtr Tp::TextChannel::create ( const ConnectionPtr &  connection,
const QString &  objectPath,
const QVariantMap &  immutableProperties 
)
static

Create a new TextChannel object.

Parameters
connectionConnection owning this channel, and specifying the service.
objectPathThe channel object path.
immutablePropertiesThe channel immutable properties.
Returns
A TextChannelPtr object pointing to the newly created TextChannel object.
bool Tp::TextChannel::hasMessagesInterface ( ) const

Return whether this channel supports the Messages interface.

If the interface is not supported, some advanced functionality will be unavailable.

This method requires TextChannel::FeatureCore to be ready.

Returns
true if the Messages interface is supported, false otherwise.
bool Tp::TextChannel::hasChatStateInterface ( ) const

Return whether this channel supports the ChatState interface.

If the interface is not supported, requestChatState() will fail and all contacts' chat states will appear to be ChannelChatStateInactive.

This method requires TextChannel::FeatureCore to be ready.

Returns
true if the ChatState interface is supported, false otherwise.
See also
requestChatState(), chatStateChanged()
bool Tp::TextChannel::canInviteContacts ( ) const

Return whether contacts can be invited into this channel using inviteContacts() (which is equivalent to Channel::groupAddContacts()).

Whether this is the case depends on the underlying protocol, the type of channel, and the user's privileges (in some chatrooms, only a privileged user can invite other contacts).

This is an alias for Channel::groupCanAddContacts(), to indicate its meaning more clearly for Text channels.

This method requires Channel::FeatureCore to be ready.

Returns
true if contacts can be invited, false otherwise.
See also
inviteContacts(), Channel::groupCanAddContacts(), Channel::groupAddContacts()
bool Tp::TextChannel::supportsMessageType ( ChannelTextMessageType  messageType) const

Return whether the provided message type is supported.

This method requires TextChannel::FeatureMessageCapabilities to be ready.

Parameters
messageTypeThe message type to check.
Returns
true if supported, false otherwise
QList< ChannelTextMessageType > Tp::TextChannel::supportedMessageTypes ( ) const

Return the message types supported by this channel.

This method requires TextChannel::FeatureMessageCapabilities to be ready.

Returns
The list of supported message types
QStringList Tp::TextChannel::supportedContentTypes ( ) const

Return a list of supported MIME content types for messages on this channel.

For a simple text channel this will be a list containing one item, "text/plain".

This list may contain the special value "*<!--x-->/<!--x-->*", which indicates that any content type is supported.

This method requires TextChannel::FeatureMessageCapabilities to be ready.

Returns
The list of MIME content types.
MessagePartSupportFlags Tp::TextChannel::messagePartSupport ( ) const

Return a set of flags indicating support for multi-part messages on this channel.

This is zero on simple text channels, or greater than zero if there is partial or full support for multi-part messages.

This method requires TextChannel::FeatureMessageCapabilities to be ready.

Returns
The flags as MessagePartSupportFlags.
DeliveryReportingSupportFlags Tp::TextChannel::deliveryReportingSupport ( ) const

Return a set of flags indicating support for delivery reporting on this channel.

This is zero if there are no particular guarantees, or greater than zero if delivery reports can be expected under certain circumstances.

This method requires TextChannel::FeatureMessageCapabilities to be ready.

Returns
The flags as DeliveryReportingSupportFlags.
QList< ReceivedMessage > Tp::TextChannel::messageQueue ( ) const

Return a list of messages received in this channel.

Messages are added to this list when they are received from the instant messaging service; the messageReceived() signal is emitted.

There is a small delay between the message being received over D-Bus and becoming available to users of this C++ API, since a small amount of additional information needs to be fetched. However, the relative ordering of all the messages in a channel is preserved.

Messages are removed from this list when they are acknowledged with the acknowledge() or forget() methods. On channels where hasMessagesInterface() returns true, they will also be removed when acknowledged by a different client. In either case, the pendingMessageRemoved() signal is emitted.

This method requires TextChannel::FeatureMessageQueue to be ready.

Returns
A list of ReceivedMessage objects.
See also
messageReceived()
ChannelChatState Tp::TextChannel::chatState ( const ContactPtr &  contact) const

Return the current chat state for contact.

If hasChatStateInterface() returns false, this method will always return ChannelChatStateInactive.

This method requires TextChannel::FeatureChatState to be ready.

Returns
The contact chat state as ChannelChatState.
void Tp::TextChannel::acknowledge ( const QList< ReceivedMessage > &  messages)
slot

Acknowledge that received messages have been displayed to the user.

Note that this method should only be called by the main handler of a channel, usually meaning the user interface process that displays the channel to the user (when a channel dispatcher is used, the handler must acknowledge messages, and other approvers or observers must not acknowledge messages).

Processes other than the main handler of a channel can free memory used by the library by calling forget() instead.

This method requires TextChannel::FeatureMessageQueue to be ready.

Parameters
messagesA list of received messages that have now been displayed.
See also
forget(), messageQueue(), messageReceived(), pendingMessageRemoved()
void Tp::TextChannel::forget ( const QList< ReceivedMessage > &  messages)
slot

Remove messages from the message queue without acknowledging them.

Note that this method frees memory used by the library, but does not free the corresponding memory in the CM process. It should be used by clients that are not the main handler for a channel; the main handler for a channel should use acknowledge() instead.

This method requires TextChannel::FeatureMessageQueue to be ready.

Parameters
messagesA list of received messages that have now been processed.
See also
acknowledge(), messageQueue(), messageReceived(), pendingMessageRemoved()
PendingSendMessage * Tp::TextChannel::send ( const QString &  text,
ChannelTextMessageType  type = ChannelTextMessageTypeNormal,
MessageSendingFlags  flags = 0 
)
slot

Request that a message be sent on this channel.

When the message has been submitted for delivery, this method will return and the messageSent() signal will be emitted.

If the message cannot be submitted for delivery, the returned pending operation will fail and no signal is emitted.

This method requires TextChannel::FeatureCore to be ready.

Parameters
textThe message body.
typeThe message type.
flagsFlags affecting how the message is sent. Note that the channel may ignore some or all flags, depending on deliveryReportingSupport(); the flags that were handled by the CM are provided in messageSent().
Returns
A PendingOperation which will emit PendingOperation::finished when the message has been submitted for delivery.
See also
messageSent()
PendingSendMessage * Tp::TextChannel::send ( const MessagePartList parts,
MessageSendingFlags  flags = 0 
)
slot

Request that a message be sent on this channel.

When the message has been submitted for delivery, this method will return and the messageSent() signal will be emitted.

If the message cannot be submitted for delivery, the returned pending operation will fail and no signal is emitted.

This method requires TextChannel::FeatureCore to be ready.

Parameters
partsThe message parts.
flagsFlags affecting how the message is sent. Note that the channel may ignore some or all flags, depending on deliveryReportingSupport(); the flags that were handled by the CM are provided in messageSent().
Returns
A PendingOperation which will emit PendingOperation::finished when the message has been submitted for delivery.
See also
messageSent()
PendingOperation* Tp::TextChannel::inviteContacts ( const QList< ContactPtr > &  contacts,
const QString &  message = QString() 
)
inlineslot
PendingOperation * Tp::TextChannel::requestChatState ( ChannelChatState  state)
slot

Set the local chat state and notify other members of the channel that it has changed.

Note that only the primary handler of the channel should set its chat state.

This method requires TextChannel::FeatureCore to be ready.

Parameters
stateThe new state.
See also
chatStateChanged()
void Tp::TextChannel::messageSent ( const Tp::Message message,
Tp::MessageSendingFlags  flags,
const QString &  sentMessageToken 
)
signal

Emitted when a message is sent, if the TextChannel::FeatureMessageSentSignal has been enabled.

This signal is emitted regardless of whether the message is sent by this client, or another client using the same channel via D-Bus.

Parameters
messageA message. This may differ slightly from what the client requested to send, for instance if it has been altered due to limitations of the instant messaging protocol used.
flagsMessageSendingFlags that were in effect when the message was sent. Clients can use these in conjunction with deliveryReportingSupport() to determine whether delivery reporting can be expected.
sentMessageTokenEither an empty QString, or an opaque token used to match the message to any delivery reports.
void Tp::TextChannel::messageReceived ( const Tp::ReceivedMessage message)
signal

Emitted when a message is added to messageQueue(), if the TextChannel::FeatureMessageQueue Feature has been enabled.

This occurs slightly later than the message being received over D-Bus; see messageQueue() for details.

Parameters
messageThe message received.
See also
messageQueue(), acknowledge(), forget()
void Tp::TextChannel::pendingMessageRemoved ( const Tp::ReceivedMessage message)
signal

Emitted when a message is removed from messageQueue(), if the TextChannel::FeatureMessageQueue Feature has been enabled. See messageQueue() for the circumstances in which this happens.

Parameters
messageThe message removed.
See also
messageQueue(), acknowledge(), forget()
void Tp::TextChannel::chatStateChanged ( const Tp::ContactPtr &  contact,
Tp::ChannelChatState  state 
)
signal

Emitted when the state of a member of the channel has changed, if the TextChannel::FeatureChatState feature has been enabled.

Local state changes are also emitted here.

Parameters
contactThe contact whose chat state changed.
stateThe new chat state for contact.
See also
chatState()
