Member Function Documentation

int LabelModel::columnCount

(

const QModelIndex &

parent = QModelIndex()

)

const

Get the number of columns for the children of the given parent.

Parameters:

parent

The number of columns for the children under the given parent. (not used)

Returns:

The number of columns for the children of the given parent. Always 1 because there is only one column.

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

Get the data of a Label specified by an index and a role.

Parameters:

	index	The index of the requested data.
	role	The role of the requested data.

Returns:

The data stored under the given role for the item referred to by the index.

	rows	The number of rows to insert.
	parent	The parent to insert the rows.

Returns:

True if successfull.

QModelIndex LabelModel::parent

(

const QModelIndex &

index

)

const

Get the parent of a specified index.

Parameters:

index

The child of the requested index.

Returns:

The parent index of the specified index.

bool LabelModel::removeRows	(	int	position,
		int	rows,
		const QModelIndex &	parent = QModelIndex()
	)

parent = QModelIndex()

)

const

Returns:

The number of rows under the given parent.

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

Sets the role data for the item at index to value.
