\title Query Messages Example
This simple example shows how to query messages stored in the system,
using the QtMobility Messaging API.
Messages are queried by using the QMessageManager interface which
provides access to the message data stored in the system. We will
use the \l{QMessageManager::queryMessages()}{queryMessages} function to
locate messages that match a filter object which defines the
properties of the messages we would like to find.
We define our query properties like this:
\snippet ../../examples/querymessages/main.cpp setup-query
Then we use these properties to extract the set of matching message
identifiers from the QMessageManager instance:
\snippet ../../examples/querymessages/main.cpp perform-query
Now we can iterate over our list of message identifiers, retrieving
a QMessage instance containing the details of each message in turn:
\snippet ../../examples/querymessages/main.cpp iterate-results
For each message we located, we now generate an output element
corresponding to each data item requested at the command line:
\snippet ../../examples/querymessages/main.cpp generate-output
Finally, we print the results accumulated for each message that
matched our query.
\snippet ../../examples/querymessages/main.cpp print-result
