49 \brief The QContactFetchRequest class allows a client to asynchronously |
|
50 request contacts from a contacts store manager. |
|
51 |
|
52 |
|
53 For a QContactFetchRequest, the resultsAvailable() signal will be emitted when the resultant |
|
54 contacts (which may be retrieved by calling contacts()), are updated, as well as if |
|
55 the overall operation error (which may be retrieved by calling error()) is updated. |
|
56 |
|
57 Please see the class documentation of QContactAbstractRequest for more information about |
|
58 the usage of request classes and ownership semantics. |
