56 \class QContactAction |
|
57 \brief The QContactAction class provides an interface for performing an |
|
58 action on a QContact or QContactDetail. |
|
59 \ingroup contacts-main |
|
60 \ingroup contacts-actions |
|
61 |
|
62 An action is anything that can be performed on a contact, or a detail of a contact. An example |
|
63 of an action might be "Send Email" or "Dial" or "Plot Navigation Route". One action may be |
|
64 implemented by multiple vendors, and indeed one vendor may provide multiple implementations of |
|
65 the same action. The name of an action identifies its semantics, while its implementation version |
|
66 distinguishes it from other implementations of the action by the same vendor. |
|
67 |
|
68 Invocation of an action is asynchronous; at some stage after calling \l invokeAction() the |
|
69 action instance will emit the \l stateChanged() signal. Any results of the action may be retrieved |
|
70 by calling \l results(), and as results become available the action will emit \l resultsAvailable(). |
|
71 |
|
72 Each instance of a QContactAction is created by a \l QContactActionFactory when |
|
73 \l QContactActionFactory::instance() is called; the caller takes ownership of the action instance. |
|

|

82 |
|
83 /*! |
|
84 \fn QContactAction::actionDescriptor() const |
|
85 Returns the descriptor which uniquely identifies this action implementation. A descriptor |
|
86 consists of an action name, a vendor name and an implementation version. |
|
87 The name of the action identifies the action provided; different implementations of an action |
|
88 with the same name must provide the same functionality, but may differ in implementation semantics. |
|
89 Hence, the action name includes the major version of the interface definition implemented. |
|
90 The vendor name is the identification string of the vendor which has provided this implementation. |
|
91 The implementation version is the (minor) version of the implementation, and is vendor-specific. |

116 performed on it; otherwise, returns false. |
|
117 Some actions may require other information to be available in order to complete successfully; in that case, |
|
118 the action will also inspect the given \a contact to ensure that it contains the information required. |
|
119 If the contact contains the required information, the function will return true; otherwise, returns false. |
