Detailed Description

The Akonadi specific implementation of the Core::StorageModel.

Definition at line 35 of file storagemodel.h.

Constructor & Destructor Documentation

◆ StorageModel()

MessageList::StorageModel::StorageModel ( QAbstractItemModel * model,
QItemSelectionModel * selectionModel,
QObject * parent = nullptr )
explicit

Create a StorageModel wrapping the specified folder.

Definition at line 76 of file storagemodel.cpp.

Member Function Documentation

◆ collectionForId()

Akonadi::Collection MessageList::StorageModel::collectionForId ( Akonadi::Collection::Id colId) const
nodiscard

Definition at line 487 of file storagemodel.cpp.

◆ columnCount()

int MessageList::StorageModel::columnCount ( const QModelIndex & parent = QModelIndex()) const
nodiscardoverridevirtual

Implements QAbstractItemModel.

Definition at line 373 of file storagemodel.cpp.

◆ containsOutboundMessages()

bool MessageList::StorageModel::containsOutboundMessages ( ) const
nodiscardoverridevirtual

Returns true if this StorageModel (folder) contains outbound messages and false otherwise.

Implements MessageList::Core::StorageModel.

Definition at line 168 of file storagemodel.cpp.

◆ data()

QVariant MessageList::StorageModel::data ( const QModelIndex & index,
int role = Qt::DisplayRole ) const
nodiscardoverridevirtual

Implements QAbstractItemModel.

Definition at line 357 of file storagemodel.cpp.

◆ displayedCollections()

Collection::List MessageList::StorageModel::displayedCollections ( ) const
nodiscard

Definition at line 127 of file storagemodel.cpp.

◆ fillMessageItemThreadingData()

void MessageList::StorageModel::fillMessageItemThreadingData ( MessageList::Core::MessageItem * mi,
int row,
ThreadingDataSubset subset ) const
overridevirtual

This method should use the inner model implementation to fill in the specified subset of threading data for the specified MessageItem from the underlying storage slot at the specified row index.

Implements MessageList::Core::StorageModel.

Definition at line 284 of file storagemodel.cpp.

◆ id()

QString MessageList::StorageModel::id ( ) const
nodiscardoverridevirtual

Returns an unique id for this Storage collection.

FIXME: This could be embedded in "name()" ?

Implements MessageList::Core::StorageModel.

Definition at line 143 of file storagemodel.cpp.

◆ index()

QModelIndex MessageList::StorageModel::index ( int row,
int column,
const QModelIndex & parent = QModelIndex() ) const
nodiscardoverridevirtual

Implements QAbstractItemModel.

Definition at line 381 of file storagemodel.cpp.

◆ initializeMessageItem()

bool MessageList::StorageModel::initializeMessageItem ( MessageList::Core::MessageItem * it,
int row,
bool bUseReceiver ) const
nodiscardoverridevirtual

This method should use the inner model implementation to fill in the base data for the specified MessageItem from the underlying storage slot at the specified row index.

Must return true if the data fetch was successful and false otherwise. For base data we intend: subject, sender, receiver, senderOrReceiver, size, date, encryption state, signature state and status. If bUseReceiver is true then the "senderOrReceiver" field must be set to the receiver, otherwise it must be set to the sender.

Implements MessageList::Core::StorageModel.

Definition at line 198 of file storagemodel.cpp.

◆ initialUnreadRowCountGuess()

int MessageList::StorageModel::initialUnreadRowCountGuess ( ) const
nodiscardoverridevirtual

Returns (a guess for) the number of unread messages: must be pessimistic (i.e.

if you have no idea just return rowCount(), which is also what the default implementation does). This must be (and is) queried ONLY when the folder is first opened. It doesn't actually need to keep the number of messages in sync as they later arrive to the storage.

Reimplemented from MessageList::Core::StorageModel.

Definition at line 182 of file storagemodel.cpp.

◆ isOutBoundFolder()

bool MessageList::StorageModel::isOutBoundFolder ( const Akonadi::Collection & c) const
nodiscardvirtual

Definition at line 160 of file storagemodel.cpp.

◆ itemForRow()

Akonadi::Item MessageList::StorageModel::itemForRow ( int row) const
nodiscard

Definition at line 457 of file storagemodel.cpp.

◆ messageForRow()

KMime::Message::Ptr MessageList::StorageModel::messageForRow ( int row) const
nodiscard

Definition at line 462 of file storagemodel.cpp.

◆ mimeData()

QMimeData * MessageList::StorageModel::mimeData ( const QList< MessageList::Core::MessageItem * > & ) const
overridevirtual

The implementation-specific mime data for this list of items.

Called when the user initiates a drag from the messagelist.

Implements MessageList::Core::StorageModel.

Definition at line 403 of file storagemodel.cpp.

◆ parent()

QModelIndex MessageList::StorageModel::parent ( const QModelIndex & index) const
nodiscardoverridevirtual

Implements QAbstractItemModel.

Definition at line 389 of file storagemodel.cpp.

◆ parentCollectionForRow()

Collection MessageList::StorageModel::parentCollectionForRow ( int row) const
nodiscard

Definition at line 467 of file storagemodel.cpp.

◆ resetModelStorage()

void MessageList::StorageModel::resetModelStorage ( )

Definition at line 505 of file storagemodel.cpp.

◆ rowCount()

int MessageList::StorageModel::rowCount ( const QModelIndex & parent = QModelIndex()) const
nodiscardoverridevirtual

Implements QAbstractItemModel.

Definition at line 395 of file storagemodel.cpp.

◆ setMessageItemStatus()

void MessageList::StorageModel::setMessageItemStatus ( MessageList::Core::MessageItem * mi,
int row,
Akonadi::MessageStatus status )
overridevirtual

This method should use the inner model implementation to associate the new status to the specified message item.

The new status should be stored (but doesn't need to be set as mi->status() itself as the caller is responsible for this).

Implements MessageList::Core::StorageModel.

Definition at line 347 of file storagemodel.cpp.

◆ updateMessageItemData()

void MessageList::StorageModel::updateMessageItemData ( MessageList::Core::MessageItem * mi,
int row ) const
overridevirtual

This method should use the inner model implementation to re-fill the date, the status, the encryption state, the signature state and eventually update the min/max dates for the specified MessageItem from the underlying storage slot at the specified row index.

Implements MessageList::Core::StorageModel.
