int QgsCptCityBrowserModel::columnCount ( const QModelIndex &  parent = QModelIndex()) const
virtual

Provides the number of columns of data exposed by the model.

List models do not provide this function because it is already implemented in QAbstractListModel.

QVariant QgsCptCityBrowserModel::data ( const QModelIndex &  index,
int  role = Qt::DisplayRole 
) const
virtual

Used to supply item data to views and delegates.

Generally, models only need to supply data for Qt::DisplayRole and any application-specific user roles, but it is also good practice to provide data for Qt::ToolTipRole, Qt::AccessibleTextRole, and Qt::AccessibleDescriptionRole. See the Qt::ItemDataRole enum documentation for information about the types associated with each role.

QgsCptCityDataItem * QgsCptCityBrowserModel::dataItem ( const QModelIndex &  idx) const

Returns a list of mime that can describe model indexes.

Returns an object that contains serialized items of data corresponding to the list of indexes specified Handles the data supplied by a drag and drop operation that ended with the given action

Definition at line 1488 of file qgscptcityarchive.cpp.

Qt::ItemFlags QgsCptCityBrowserModel::flags ( const QModelIndex &  index) const
virtual

Used by other components to obtain information about each item provided by the model.

In many models, the combination of flags should include Qt::ItemIsEnabled and Qt::ItemIsSelectable.

QVariant QgsCptCityBrowserModel::headerData ( int  section,
Qt::Orientation  orientation,
int  role = Qt::DisplayRole 
) const
virtual

Provides views with information to show in their headers.

The information is only retrieved by views that can display header information.

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

Returns the index of the item in the model specified by the given row, column and parent index.

Definition at line 1604 of file qgscptcityarchive.cpp.

QModelIndex QgsCptCityBrowserModel::parent ( const QModelIndex &  index) const
virtual

Returns the parent of the model item with the given index.

If the item has no parent, an invalid QModelIndex is returned.
