int rowCount ( const QModelIndex parent = QModelIndex()) const

Returns the number of rows in the model.

This value corresponds to the size of the list passed through setModelData.

Parameters
parentThe optional parent argument is used in most models to specify the parent of the rows to be counted. Because this is a list if a valid parent is specified the result will always be 0.

Reimplemented from QAbstractItemModel.

QAbstractItemModel::rowCount
QVariant data ( const QModelIndex index,
int  role = Qt::DisplayRole 
) const

Returns data from the item with the given index for the specified role.

If the view requests an invalid index, an invalid variant is returned.

Reimplemented from QAbstractItemModel.

See also
QAbstractItemModel::data
Qt::ItemDataRole
Qt::ItemFlags flags ( const QModelIndex index) const

Reimplemented to show unavailable devices as disabled (but still selectable).

QList<int> tupleIndexOrder ( ) const

Returns a list of indexes in the same order as they are in the model.

The indexes come from the ObjectDescription::index method.

This is useful to let the user define a list of preference.

int tupleIndexAtPositionIndex ( int  positionIndex) const

Returns the ObjectDescription::index for the tuple at the given position positionIndex.

For example a QComboBox will give you the currentIndex as the position in the list. But to select the according AudioOutputDevice using AudioOutputDevice::fromIndex you can use this method.

Parameters
positionIndexThe position in the list.
QMimeData* mimeData ( ObjectDescriptionType  type,
const QModelIndexList indexes 
) const

Returns the MIME data that dropMimeData() can use to create new items.

void moveUp ( const QModelIndex index)

Moves the item at the given index up.

In the resulting list the items at index.row() and index.row() - 1 are swapped.

Connected views are updated automatically.

void moveDown ( const QModelIndex index)

Moves the item at the given index down.

In the resulting list the items at index.row() and index.row() + 1 are swapped.

Connected views are updated automatically.
