data()

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

Retrieves data from the cache or source 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.

flags()

Qt::ItemFlags InterfaceTreeCacheModel::flags

(

const QModelIndex &

index

)

const

Parameters

index

The model index.

Returns

The item flags.

getColumnContent()

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

Parameters

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

Returns

The cached data variant.

rowCount()

int InterfaceTreeCacheModel::rowCount

(

const QModelIndex &

parent = QModelIndex()

)

const

Returns the number of rows under a given parent.

Parameters

parent

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

Returns

The number of rows.

setData()

bool InterfaceTreeCacheModel::setData	(	const QModelIndex &	index,
		const QVariant &	value,
		int	role = Qt::EditRole
	)

Sets data in the cache for a given index and role.

Parameters

index	The model index to update.
value	The value to set.
