Constructor & Destructor Documentation

SupportedProtocolsModel()

SupportedProtocolsModel::SupportedProtocolsModel ( QObject * parent = Q_NULLPTR )

explicit

Constructs an empty model; call populate() to load protocol data.

Parameters

parent

Optional parent QObject.

Member Function Documentation

columnCount()

int SupportedProtocolsModel::columnCount ( const QModelIndex & parent = QModelIndex() ) const

override

Returns the number of columns in the model.

Parameters

parent

Unused.

Returns

Number of columns (colLast).

data()

QVariant SupportedProtocolsModel::data ( const QModelIndex & index, int role ) const

override

Returns data for the given model index and role.

Parameters

index	Model index of the cell to query.
role	Qt item data role.

Returns

The requested data, or an invalid QVariant if not applicable.

fieldCount()

int SupportedProtocolsModel::fieldCount ( )

inline

Returns the total number of protocol fields loaded by populate().

Returns

Field count across all protocols.

headerData()

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

override

Returns column header labels for the supported-protocols table.

Parameters

section	Column index.
orientation	Qt::Horizontal for column headers.
role	Qt item data role.

Returns

Header label string, or an invalid QVariant if not applicable.

index()

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

override

Returns the model index for the item at row and column under parent.

Parameters

row	Row within the parent item.
column	Column index.
parent	Parent model index; invalid index for top-level items.

Returns

Model index for the requested item.

parent()

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

override

Returns the parent index of the item at index.

Parameters

index

Child model index.

Returns

Parent model index, or an invalid index for top-level items.

rowCount()

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

override

Returns the number of child rows under parent.

Parameters

parent

Parent model index; invalid index for the root.

Returns

Number of child items.
