Detailed Description

The class is used to represent the information of an MITK MultiLabel segmentation instance (labels, spatial groups...).

Member Enumeration Documentation

ItemModelRole

enum QmitkMultiLabelTreeModel::ItemModelRole

Enumerator
LabelDataRole	This role returns the label object that is associated with an index. On group level it always returns an invalid QVariant On label level (with multiple instances) it returns the first label instance). On instance level it returns the label instance object.
LabelValueRole	This role returns only the label value of the label that would be returned by LabelDataRole.
LabelInstanceDataRole	Simelar to LabelDataRole, but only returns a valid QVariant if index points only to a specific instance (so either instance level or label level with only one instance). You can use that role if you want to assure that only one specific label instance is referenced by the index.
LabelInstanceValueRole	Simelar to LabelValueRole, but like LabelInstanceDataRole only returns a valid QVariant if index points only to a specific instance (so either instance level or label level with only one instance). You can use that role if you want to assure that only one specific label instance is referenced by the index.
GroupIDRole	This role returns the group ID the item/index belongs to.

Member Function Documentation

columnCount()

int QmitkMultiLabelTreeModel::columnCount ( const QModelIndex &  parent = QModelIndex() ) const

override

data()

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

dataAvailable

void QmitkMultiLabelTreeModel::dataAvailable ( )

signal

FirstLabelInstanceIndex()

QModelIndex QmitkMultiLabelTreeModel::FirstLabelInstanceIndex

(

const QModelIndex &

currentIndex

)

const

Returns the index to the first child node (or itself) in the tree that behaves like an instance (label node with only one instance or instance node). If current index is at the end, an invalid index is returned. If an invalid index is passed into the methods, the search starts at the root; thus the whole tree is search for the first label instance.

const

GetLabelInstancesOfSameLabelClass()

std::vector<LabelValueType> QmitkMultiLabelTreeModel::GetLabelInstancesOfSameLabelClass

(

const QModelIndex &

currentIndex

)

const

Returns a vector containing all label values of all label instances that belong to the same label class like the passed index.

If index points to a group or invalid, nothing will be returned.

Precondition

currentIndex must be valid and point to a label (class or instance).

GetLabelsInSubTree()

std::vector<LabelValueType> QmitkMultiLabelTreeModel::GetLabelsInSubTree

(

const QModelIndex &

currentIndex

)

const

‍** Returns the index to the next node in the tree that behaves like an instance (label node with only one instance

Returns a vector containing all label values of the passed currentIndex or its child items.

GetModelUpdateOngoing()

bool QmitkMultiLabelTreeModel::GetModelUpdateOngoing

(

)

const

GetNearestLabelValueToLastChange()

LabelValueType QmitkMultiLabelTreeModel::GetNearestLabelValueToLastChange

(

)

const

Returns the label value that is in the tree the closest instance to the latest removed label. If there was no label removal so far or no label is left, the function will return mitk::MultiLabelSegmentation::UNLABELED_VALUE.

GetSegmentation()

)

const

indexOfLabel()

QModelIndex QmitkMultiLabelTreeModel::indexOfLabel

(

labelValue

)

const

returns the index of a passed label value (always first column). If label value does not exist in segmentation or segmentation is not set an invalid index will be returned.
