Detailed Description

Hierarchical incidence model.

Useful as a source for TodoModel for example.

Definition at line 24 of file incidencetreemodel.h.

Constructor & Destructor Documentation

◆ IncidenceTreeModel() [1/2]

IncidenceTreeModel::IncidenceTreeModel ( QObject * parent = nullptr)
explicit

Constructs a new IncidenceTreeModel.

Definition at line 628 of file incidencetreemodel.cpp.

◆ IncidenceTreeModel() [2/2]

IncidenceTreeModel::IncidenceTreeModel ( const QStringList & mimeTypes,
QObject * parent = nullptr )
explicit

Constructs a new IncidenceTreeModel which will only show incidences of type mimeTypes.

Common use case is a to-do tree.

This constructor is offered for performance reasons. The filtering has zero overhead, and we avoid stacking mime type filter proxy models.

If you're more concerned about clean design than performance, use the default constructor and stack a Akonadi::EntityMimeTypeFilterModel on top of this one.

Definition at line 635 of file incidencetreemodel.cpp.

Member Function Documentation

◆ batchInsertionFinished

void Akonadi::IncidenceTreeModel::batchInsertionFinished ( )
signal

Signals that we finished doing a batch of insertions.

One rowsInserted() signal from the ETM, will make IncidenceTreeModel generate several rowsInserted(), layoutChanged() or rowsMoved() signals.

A tree view can use this signal to know when to call KConfigViewStateSaver::restore() to restore expansion states. Listening to rowsInserted() signals would be a performance problem.

◆ columnCount()

int IncidenceTreeModel::columnCount ( const QModelIndex & parent = QModelIndex()) const
overridevirtual

Implements QAbstractItemModel.

Definition at line 672 of file incidencetreemodel.cpp.

◆ data()

QVariant IncidenceTreeModel::data ( const QModelIndex & index,
int role ) const
overridevirtual

Reimplemented from QAbstractProxyModel.

Definition at line 644 of file incidencetreemodel.cpp.

◆ hasChildren()

bool IncidenceTreeModel::hasChildren ( const QModelIndex & parent = QModelIndex()) const
overridevirtual

Reimplemented from QAbstractProxyModel.

Definition at line 817 of file incidencetreemodel.cpp.

◆ index()

QModelIndex IncidenceTreeModel::index ( int row,
int column,
const QModelIndex & parent = QModelIndex() ) const
overridevirtual

Implements QAbstractItemModel.

Definition at line 783 of file incidencetreemodel.cpp.

◆ indexChangedParent

void Akonadi::IncidenceTreeModel::indexChangedParent ( const QModelIndex & index)
signal

This signal is emitted whenever an index changes parent.

The view can then expand the parent if desired. This is better than the view waiting for "rows moved" signals because those signals are also sent when the model is initially populated.

◆ item()

Akonadi::Item IncidenceTreeModel::item ( const QString & incidenceUid) const

Returns the akonadi item containing the incidence with incidenceUid.

Definition at line 833 of file incidencetreemodel.cpp.

◆ mapFromSource()

QModelIndex IncidenceTreeModel::mapFromSource ( const QModelIndex & sourceIndex) const
overridevirtual

Implements QAbstractProxyModel.

Definition at line 688 of file incidencetreemodel.cpp.

◆ mapToSource()

QModelIndex IncidenceTreeModel::mapToSource ( const QModelIndex & proxyIndex) const
overridevirtual

Implements QAbstractProxyModel.

Definition at line 713 of file incidencetreemodel.cpp.

◆ parent()

QModelIndex IncidenceTreeModel::parent ( const QModelIndex & child) const
overridevirtual

Implements QAbstractItemModel.

Definition at line 748 of file incidencetreemodel.cpp.

◆ rowCount()

int IncidenceTreeModel::rowCount ( const QModelIndex & parent = QModelIndex()) const
overridevirtual

Implements QAbstractItemModel.

Definition at line 657 of file incidencetreemodel.cpp.

◆ setSourceModel()

void IncidenceTreeModel::setSourceModel ( QAbstractItemModel * sourceModel)
overridevirtual

Reimplemented from QAbstractProxyModel.

Definition at line 680 of file incidencetreemodel.cpp.
