Constructor & Destructor Documentation

ExpertInfoProxyModel()

ExpertInfoProxyModel::ExpertInfoProxyModel

(

QObject *

parent = 0

)

Constructs a new ExpertInfoProxyModel.

Parameters

parent

The parent QObject, defaults to 0.

Member Function Documentation

columnCount()

int ExpertInfoProxyModel::columnCount

(

const QModelIndex &

parent = QModelIndex()

)

const

Returns the number of columns under a given parent.

Parameters

parent

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

Returns

The number of columns.

data()

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

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

Parameters

index	The proxy model index.
role	The data role requested.

Returns

The data associated with the index and role.

filterAcceptItem()

bool ExpertInfoProxyModel::filterAcceptItem ( ExpertPacketItem &  item ) const

protected

Checks if an individual expert packet item matches the current filter criteria.

Parameters

item	The expert packet item to check.

Returns

True if the item is accepted, false otherwise.

filterAcceptsRow()

bool ExpertInfoProxyModel::filterAcceptsRow ( int  sourceRow, const QModelIndex &  sourceParent  ) const

virtual

Determines whether a row from the source model should be displayed.

Parameters

sourceRow	The row in the source model.
sourceParent	The parent index in the source model.

Returns

True if the row is accepted, false otherwise.

hasChildren()

bool ExpertInfoProxyModel::hasChildren

(

const QModelIndex &

parent = QModelIndex()

)

const

Checks if a given parent index has any child elements.

Parameters

parent

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

Returns

True if the parent has children, false otherwise.

headerData()

QVariant ExpertInfoProxyModel::headerData	(	int	section,
		Qt::Orientation	orientation,
		int	role = Qt::DisplayRole
	)		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 (defaults to Qt::DisplayRole).

Returns

The header data.

lessThan()

bool ExpertInfoProxyModel::lessThan ( const QModelIndex &  source_left, const QModelIndex &  source_right  ) const

protected

Compares two source indices to determine their sort order.

Parameters

source_left	The first source index.
source_right	The second source index.

Returns

True if the left item should appear before the right item.

setSeverityFilter()

void ExpertInfoProxyModel::setSeverityFilter	(	int	severity,
		bool	hide
	)

Sets whether a specific severity level should be hidden or shown.

Parameters

severity	The severity level identifier.
hide	True to hide the severity, false to show it.

setSeverityMode()

void ExpertInfoProxyModel::setSeverityMode

(

enum SeverityMode

mode

)

Sets the severity mode for the proxy model.

Parameters

mode	The severity mode to apply.

setSummaryFilter()

void ExpertInfoProxyModel::setSummaryFilter

(

const QString &

filter

)

Sets the text filter used to filter items by their summary.

Parameters

filter

The filter text or regular expression.
