bool QmitkPointListModel::GetModelIndexForPointID	(	mitk::PointSet::PointIdentifier	id,
		QModelIndex &	index
	)		const

returns a QModelIndex for a given point ID

Documentation The mitk::PointSet uses a map to store points in an ID<–>Point relation. The IDs are not neccesarily continuously numbered, therefore, we can not directly use the point ID as a QModelIndex. This method returns a QModelIndex for a given point ID in the outgoing parameter index.

Parameters

[in]	mitk::PointSet::PointIdentifier	id The point ID for which the QModelIndex will be created
[out]	QModelIndex&	index if a point with the ID id was found, index will contain a corresponding QModelIndex for that point

Returns: returns true, if a valid QModelIndex was created, false otherwise

get point and point ID that correspond to a given QModelIndex

The mitk::PointSet uses a map to store points in an ID<–>Point relation. The IDs are not neccesarily continuously numbered, therefore, we can not directly use the QModelIndex as point ID. This method returns the point and the corresponding point id for a given QModelIndex. The point and the point ID are returned in the outgoing parameters p and id. If a valid point and ID were found, the method returns true, otherwise it returns false

Parameters

[in]	QModelIndex	&index the index for which a point is requested. The row() part of the index is used to find a corresponding point
[out]	mitk::Point3D&	p If a valid point is found, it will be stored in the p parameter
[out]	mitk::PointSet::PointIdentifier&	id If a valid point is found, the corresponding ID will be stored in id
