Detailed Description

The QMailMessageSortKey class defines the parameters used for sorting a subset of queried messages from the mail store.

A QMailMessageSortKey is composed of a message property to sort and a sort order. The QMailMessageSortKey class is used in conjunction with the QMailStore::queryMessages() function to sort message results according to the criteria defined by the sort key.

For example: To create a query for all messages sorted by their timestamp in decending order:

    QMailMessageSortKey sortArrivalTimeKey(QMailMessageSortKey::TimeStamp,Qt::DescendingOrder);
    QMailIdList results = QMailStore::instance()->queryMessages(QMailMessageKey(),sortArrivalTimeKey);

See also QMailStore and QMailMessageKey.

Member Function Documentation

QMailMessageSortKey::QMailMessageSortKey ()

Create a QMailMessageSortKey with specifying matching parameters.

A default-constructed key (one for which isEmpty() returns true) sorts no messages.

The result of combining an empty key with a non-empty key is the same as the original non-empty key.

The result of combining two empty keys is an empty key.

QMailMessageSortKey::QMailMessageSortKey ( Property p, Qt::SortOrder order = Qt::AscendingOrder )

Construct a QMailMessageSortKey which sorts a set of results based on the QMailMessageSortKey::Property p and the Qt::SortOrder order

QMailMessageSortKey::QMailMessageSortKey ( const QMailMessageSortKey & other )

Create a copy of the QMailMessageSortKey other.

QMailMessageSortKey::~QMailMessageSortKey ()   [virtual]

Destroys this QMailMessageSortKey.

bool QMailMessageSortKey::isEmpty () const

Returns true if the key remains empty after default construction; otherwise returns false.

bool QMailMessageSortKey::operator!= ( const QMailMessageSortKey & other ) const

Returns true if the value of this key is not the same as the key other. Returns false otherwise.

QMailMessageSortKey QMailMessageSortKey::operator& ( const QMailMessageSortKey & other ) const

Returns a key that is the logical AND of this key and the value of key other.

QMailMessageSortKey & QMailMessageSortKey::operator&= ( const QMailMessageSortKey & other )

Performs a logical AND with this key and the key other and assigns the result to this key.

QMailMessageSortKey & QMailMessageSortKey::operator= ( const QMailMessageSortKey & other )

Assign the value of the QMailMessageSortKey other to this.

bool QMailMessageSortKey::operator== ( const QMailMessageSortKey & other ) const

Returns true if the value of this key is the same as the key other. Returns false otherwise.
