`from PyKDE4.akonadi import *`

Inherits: QAbstractTableModel → QAbstractItemModel → QObject
Namespace: Akonadi

## Detailed Description

A table model for items.

A self-updating table model that shows all items of a collection.

     QTableView *view = new QTableView( this );

     view->setModel( model );

     model->setCollection( Akonadi.Collection.root() );

## Signal Documentation

collectionChanged | ( | Akonadi.Collection | collection
| ) |  |  |

This signal is emitted whenever setCollection is called.

Parameters:

  | collection | The new collection.

Signal syntax:
  `QObject.connect(source, SIGNAL("collectionChanged(const Akonadi::Collection&)"), target_slot)`

## Method Documentation

__init__ | ( | self, |
|  | QObject | parent=0
| ) |  |  |

Creates a new item model.

Parameters:

  | parent | The parent object.

Akonadi.Collection collection | ( |  | self ) |

Returns the collection being displayed in the model.

int columnCount | ( | self, |
|  | QModelIndex | parent=QModelIndex()
| ) |  |  |

QVariant data | ( | self, |
|  | QModelIndex | index,
|  | int | role=Qt.DisplayRole
| ) |  |  |

bool dropMimeData | ( | self, |
|  | QMimeData | data,
|  | Qt::DropAction | action,
|  | int | row,
|  | int | column,
|  | QModelIndex | parent
| ) |  |  |

Akonadi.ItemFetchScope fetchScope | ( |  | self ) |

Returns the item fetch scope.

Since this returns a reference it can be used to conveniently modify the current scope in-place, i.e. by calling a method on the returned reference without storing it in a local variable. See the ItemFetchScope documentation for an example.

Returns:
  a reference to the current item fetch scope.

See also:
  setFetchScope() for replacing the current item fetch scope.

Qt::ItemFlags flags | ( | self, |
|  | QModelIndex | index
| ) |  |  |

QVariant headerData | ( | self, |
|  | int | section,
|  | Qt::Orientation | orientation,
|  | int | role=Qt.DisplayRole
| ) |  |  |

QModelIndex indexForItem | ( | self, |
|  | Akonadi.Item | item,
|  | int | column
| ) |  |  |

Returns the model index for the given item, with the given column.

Parameters:

  | item | The item to find.
  | column | The column for the returned index.

Akonadi.Item itemForIndex | ( | self, |
|  | QModelIndex | index
| ) |  |  |

Returns the item at the given index.

QMimeData mimeData | ( | self, |
|  | [QModelIndex] | indexes
| ) |  |  |

QStringList mimeTypes | ( |  | self ) |

int rowCount | ( | self, |
|  | QModelIndex | parent=QModelIndex()
| ) |  |  |

Akonadi.Session session | ( |  | self ) |

Returns the Session object used for all operations by this model.

setCollection | ( | self, |
|  | Akonadi.Collection | collection
| ) |  |  |

Sets the collection the model should display. If the collection has changed, the model is reset and a new message listing is requested from the Akonadi storage.

Parameters:

  | collection | The collection.

setFetchScope | ( | self, |
|  | Akonadi.ItemFetchScope | fetchScope
| ) |  |  |

Sets the item fetch scope.

The ItemFetchScope controls how much of an item's data is fetched from the server, e.g. whether to fetch the full item payload or only meta data.

Parameters:

  | fetchScope | The new scope for item fetch operations.

See also:
  fetchScope()

Qt::DropActions supportedDropActions | ( |  | self ) |
