## 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

  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,
|  | [QModelIndex] | indexes
| ) |  |  |

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

QStringList mimeTypes | ( | self, |
|  | Phonon.ObjectDescriptionType | type
| ) |  |  |

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.

  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.
