Detailed Description

A table model representing the system's available capture interfaces.

Constructor & Destructor Documentation

InterfaceTreeModel()

InterfaceTreeModel::InterfaceTreeModel

(

QObject *

parent

)

Constructs a new InterfaceTreeModel.

Parameters

parent

The parent QObject.

This is the data model for interface trees. It implies, that the index within global_capture_opts.all_ifaces is identical to the row. This is always the case, even when interfaces are hidden by the proxy model. But for this to work, every access to the index from within the view, has to be filtered through the proxy model.

Member Function Documentation

columnCount()

int InterfaceTreeModel::columnCount

(

const QModelIndex &

parent = QModelIndex()

)

const

Returns the number of columns in the table model.

Parameters

parent

The parent model index (defaults to an invalid QModelIndex).

Returns

The number of columns.

data()

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

Retrieves data from the model for a given index and role.

Parameters

index	The model index.
role	The data role requested (defaults to Qt::DisplayRole).

Returns

The data associated with the index and role.

getColumnContent()

QVariant InterfaceTreeModel::getColumnContent	(	int	idx,
		int	col,
		int	role = Qt::DisplayRole
	)

Gets the content for a specific column and row directly.

Parameters

idx	The row index.
col	The column index.
role	The data role (defaults to Qt::DisplayRole).

Returns

The requested data variant.

headerData()

QVariant InterfaceTreeModel::headerData	(	int	section,
		Qt::Orientation	orientation,
		int	role
	)		const

Retrieves the header data for a specific section and role.

Parameters

section	The column or row section.
orientation	The orientation of the header.
role	The data role requested.

Returns

The header data.

interfaceError()

QString InterfaceTreeModel::interfaceError

(

)

Retrieves any current interface-related error messages.

Returns

The error message string.

interfaceListChanged

void InterfaceTreeModel::interfaceListChanged ( )

slot

Slot triggered when the global list of available interfaces changes.

The interface list has changed. global_capture_opts.all_ifaces may have been reloaded or changed with current data. beginResetModel() and endResetModel() will signalize the proxy model and the view, that the data has changed and the view has to reload

rowCount()

int InterfaceTreeModel::rowCount

(

const QModelIndex &

parent = QModelIndex()

)

const

Returns the number of rows (interfaces) under a given parent.

Parameters

parent

The parent model index (defaults to an invalid QModelIndex).

Returns

The number of rows.

selectedDevices()

QItemSelection InterfaceTreeModel::selectedDevices

(

)

Retrieves the currently selected devices as an item selection.

Returns

A QItemSelection representing the selected interfaces.

updateSelectedDevices()

bool InterfaceTreeModel::updateSelectedDevices

(

QItemSelection

sourceSelection

)

Updates the internal state of selected devices based on a UI selection.

Parameters

sourceSelection

The selection from the view.

Returns

True if the selection state changed successfully, false otherwise.

updateStatistic()

void InterfaceTreeModel::updateStatistic

(

unsigned int

row

)

Triggers an update of the statistics (like sparklines) for a specific row.

Parameters

row	The row index of the interface to update.

Member Data Documentation

DefaultNumericValue

const QString InterfaceTreeModel::DefaultNumericValue = QObject::tr("default")

static

A default placeholder string for unavailable numeric values.
