void QgsCptCityBrowserModel::addRootItems ( )

protected

void QgsCptCityBrowserModel::beginInsertItems ( QgsCptCityDataItem *  parent, int  first, int  last  )

slot

void QgsCptCityBrowserModel::beginRemoveItems ( QgsCptCityDataItem *  parent, int  first, int  last  )

slot

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.

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

void QgsCptCityBrowserModel::endInsertItems ( )

slot

void QgsCptCityBrowserModel::endRemoveItems ( )

slot

void QgsCptCityBrowserModel::fetchMore

(

const QModelIndex &

parent

)

QModelIndex QgsCptCityBrowserModel::findItem	(	QgsCptCityDataItem *	item,
		QgsCptCityDataItem *	parent = 0
	)		const

QModelIndex QgsCptCityBrowserModel::findPath

(

QString

path

)

return index of a path

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.

bool QgsCptCityBrowserModel::hasChildren

(

const QModelIndex &

parent = QModelIndex()

)

const

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()  ) const

virtual

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

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.

void QgsCptCityBrowserModel::refresh

(

QString

path

)

void QgsCptCityBrowserModel::refresh

(

const QModelIndex &

index = QModelIndex()

)

void QgsCptCityBrowserModel::reload

(

)

void QgsCptCityBrowserModel::removeRootItems ( )

protected

int QgsCptCityBrowserModel::rowCount ( const QModelIndex &  parent = QModelIndex() ) const

virtual

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