bool QgsCptCityBrowserModel::canFetchMore ( const QModelIndex &  parent) const
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.

Definition at line 1482 of file qgscptcityarchive.cpp.

void QgsCptCityBrowserModel::connectItem ( QgsCptCityDataItem item)
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

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

Provides views with information to show in their headers.

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

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