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
