Detailed Description

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

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

For example: To create a query for all folders sorted by the name in ascending order:

    QMailFolderSortKey sortNameKey(QMailFolderSortKey::Name,Qt::Ascending);
    QMailIdList results = QMailStore::instance()->queryFolders(QMailFolderKey(),sortNameKey);

See also QMailStore and QMailFolderKey.

Member Function Documentation

QMailFolderSortKey::QMailFolderSortKey ()

Create a QMailFolderSortKey with specifying matching parameters.

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

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.

QMailFolderSortKey::QMailFolderSortKey ( const Property & p, const Qt::SortOrder & order = Qt::AscendingOrder )

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

QMailFolderSortKey::QMailFolderSortKey ( const QMailFolderSortKey & other )

Create a copy of the QMailFolderSortKey other.

QMailFolderSortKey::~QMailFolderSortKey ()   [virtual]

Destroys this QMailFolderSortKey.

bool QMailFolderSortKey::isEmpty () const

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

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

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

QMailFolderSortKey QMailFolderSortKey::operator& ( const QMailFolderSortKey & other ) const

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

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

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

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

Assign the value of the QMailFolderSortKey other to this.

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

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