61 |
|
62 \brief The QMessage class provides a convenient interface for working with messages. |
|
63 |
|
64 \ingroup messaging |
|
65 |
|
66 QMessage supports a number of types. Including internet email messages, |
|
67 and the telephony types SMS and MMS. |
|
68 |
|
69 The QMessageId identifier for a message is returned by id(). Messages can be constructed by |
|
70 retrieval from the messaging store via their identifier using QMessageManager::message(). A |
|
71 QMessage can also be constructed piece by piece using functions such as |
|
72 setType(), setFrom(), setTo(), setSubject(), setBody() and appendAttachments(). |
|
73 |
|
74 If a message has been modified since it was last constructed isModified() returns true. |
|
75 |
|
76 A list of attachments identifiers will be returned by attachmentIds() and an identifier for the |
|
77 message body will be returned by bodyId(). Attachments can be appended to the content of the |
|
78 message using appendAttachments(), the body of the message can be set with setBody(). |
|
79 |
|
80 The folder and account a message is associated with are returned by parentFolderId() and |
|
81 parentAccountId() respectively. |
|
82 |
|
83 Message data that is less commonly accessed or relatively large should be lazily retrieved |
|
84 on demand by the associated getter function. |
|
85 |
|
86 Only phone numbers are valid destination addresses for SMS messages, only email addresses are valid |
|
87 destination addresses for Email messages, MMS messages may be addressed to either phone numbers |
|
88 or email addresses. |
