Method Documentation
__init__ | ( | self, | ||
QAbstractListModel | a0 | |||
) |
QVariant data | ( | self, | ||
QModelIndex | index, | |||
int | role=Qt.DisplayRole | |||
) |
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.

- QAbstractItemModel.data
- See also:
- Qt.ItemDataRole
bool dropMimeData | ( | self, | ||
Phonon.ObjectDescriptionType | type, | |||
QMimeData | data, | |||
Qt.DropAction | action, | |||
int | row, | |||
int | column, | |||
QModelIndex | parent | |||
) |
Qt.ItemFlags flags | ( | self, | ||
QModelIndex | index | |||
) |
Reimplemented to show unavailable devices as disabled (but still selectable).
QMimeData mimeData | ( | self, | ||
Phonon.ObjectDescriptionType | type, | |||
QModelIndexList | indexes | |||
) |
Returns the MIME data that dropMimeData() can use to create new items.
QStringList mimeTypes | ( | self, | ||
Phonon.ObjectDescriptionType | type | |||
) |
[QExplicitlySharedDataPointer |

( | self, | ||
QModelIndex | index | |||
) |
moveDown | ( | self, | ||
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.
moveUp | ( | self, | ||
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.
bool removeRows | ( | self, | ||
int | row, | |||
int | count, | |||
QModelIndex | parent=QModelIndex() | |||
) |
int rowCount | ( | self, | ||
QModelIndex | parent=QModelIndex() | |||
) |
Returns the number of rows in the model. This value corresponds to the size of the list passed through setModelData.
- Parameters:
-
parent The 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.
- See also:
- QAbstractItemModel.rowCount

Qt.DropActions supportedDropActions | ( | self ) |
int tupleIndexAtPositionIndex | ( | self, | ||
int | positionIndex | |||
) |
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:
-
positionIndex The position in the list.
[int] tupleIndexOrder | ( | self ) |
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.
