TpSimpleObserverTpSimpleObserver — a subclass of TpBaseClient implementing a simple Observer |
TpSimpleObserver implements TpSvcClient, TpSvcClientObserver, TpSvcClientApprover, TpSvcClientHandler and TpSvcClientInterfaceRequests.
This class makes it easier to write TpSvcClient implementing the TpSvcClientObserver interface.
A typical simple observer would look liks this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
static void my_observe_channel (TpSimpleObserver *observer, TpAccount *account, TpConnection *connection, TpChannel *channel, TpChannelDispatchOperation *dispatch_operation, GList *requests, TpObserveChannelContext *context, gpointer user_data) { /<!-- -->* do something useful with the channel here *<!-- -->/ tp_observe_channel_context_accept (context); } client = tp_simple_observer_new (NULL, TRUE, "MyObserver", FALSE, my_observe_channel, user_data); tp_base_client_take_observer_filter (client, tp_channel_filter_new_for_text_chats ()); tp_base_client_register (client, NULL); |

Signature of the implementation of the ObserveChannel method.
This function must call either tp_observe_channel_context_accept()
,
tp_observe_channel_context_delay()
or tp_observe_channel_context_fail()
on context
before it returns.

is NULL
a new TpAutomaticClientFactory will be used.
