Detailed Description

Item model for subject hierarchy.

It is associated to the pseudo-singleton subject hierarchy node, and it creates one model item for each subject hierarchy item. It handles reparenting, reordering, etc. The whole model is regenerated when the Modified event is invoked on the subject hierarchy node, but only the individual items are updated when per-item events are invoked (such as vtkMRMLSubjectHierarchyNode::SubjectHierarchyItemModifiedEvent)

Member Typedef Documentation

◆ Superclass

typedef QStandardItemModel qMRMLSubjectHierarchyModel::Superclass

Definition at line 74 of file qMRMLSubjectHierarchyModel.h.

Member Enumeration Documentation

◆ ItemDataRole

enum qMRMLSubjectHierarchyModel::ItemDataRole
Enumerator
SubjectHierarchyItemIDRole 

Unique ID of the item, typed vtkIdType.

VisibilityRole 

Integer that contains the visibility property of an item. It is closely related to the item icon.

TransformIDRole 

MRML node ID of the parent transform.

LastRole 

Must stay the last enum in the list.

Definition at line 78 of file qMRMLSubjectHierarchyModel.h.

Property Documentation

◆ idColumn

int qMRMLSubjectHierarchyModel::idColumn
readwrite

Control in which column the data MRML node IDs are displayed (Qt::DisplayRole). A value of -1 hides it. Hidden by default (value of -1)

Definition at line 71 of file qMRMLSubjectHierarchyModel.h.

◆ nameColumn

int qMRMLSubjectHierarchyModel::nameColumn
readwrite

Control in which column the data MRML node names or if not assigned then subject hierarchy item names are displayed (Qt::DisplayRole). The icons corresponding to the role provided by the owner subject hierarchy plugin is also displayed in this column (Qt::DecorationRole). A value of -1 hides it. First column (0) by default. If no property is set in a column, nothing is displayed.

Definition at line 60 of file qMRMLSubjectHierarchyModel.h.

◆ transformColumn

int qMRMLSubjectHierarchyModel::transformColumn
readwrite

Control in which column the parent transforms are displayed A MRML node combobox is displayed in the row of the transformable nodes, in which the current transform is selected. The user can change the transform using the combobox. A value of -1 (default) hides the column

Definition at line 68 of file qMRMLSubjectHierarchyModel.h.

◆ visibilityColumn

int qMRMLSubjectHierarchyModel::visibilityColumn
readwrite

Control in which column data MRML node visibility are displayed (Qt::DecorationRole). A value of -1 hides it. Hidden by default (value of -1).
