Qt Messaging Module

The Qt Messaging module offers messaging related services such as SMS and email support. It is based on the Base module.

The following configure line can be used to build the Base and Messaging module only:

    ./configure -modules messaging -device xyz

Note that not specifying a device profile would result in the reference device being build.

Feature description

The Qt Extended Messaging module consist of three major components. The first part is the Messaging library which connects the two remaining parts. The second major component is the messaging server which is responsible for the handling of incoming and outgoing messages.

The last component is the message application. It provides the user interface and incorporates composer and viewer plug-ins. The plug-in system ensures the ability to integrate not yet known message types.

FeatureDetails
Messaging APIThe Qt Extended Messaging Library provides a set of APIs that support the most common operations related to arbitrary messages such as creation, modification, retrieval, storage and display of messages. It defines interfaces which enable the integration of new message types. Therefore multiple applications can access the data independ of their storage and if necessary on a concurrent base.
Message serverThe Message server daemon can send and retrieve messages of various types from multiple sources such as POP and IMAP accounts or a local SIM card. It forms the back-end of the Qt Extended Messaging framework.
Messages clientThe Messages Client interacts with the message server via the Messaging library. It enables the user to interact with the message server. Composer and Viewer plug-ins are utilized to support mulitple types of messages. Currently the following types of messages can be composed/viewed:
  • Emails
  • SMS
  • MMS
  • Voice/Video Messages
  • Instant messages (depends on IPComms module)
SMIL supportThe qtopiasmil library contains classes which render SMIL messages which are MMS slide shows.

Software components

The Messaging module includes the following software components:

  • libraries/qtopiamail
  • libraries/qtopiapim
  • libraries/qtopiasmil
  • Messages client
  • tools/messageserver (MessageServer)
  • Message composer plug-ins (see src/plugins/composers)
  • Message viewer plug-ins (see src/plugins/viewers)

The exact list of components included in this module can be found in $QPEDIR/src/module_messaging.pri.

The test plan for the Messaging module summarizes the Quality Assurance procedures for this module. The results of these test are available here.
