Detailed Description

qMRMLSceneModel has at least 1 column with the scene as a top level item. See below an example of model when nameColumn = 0 (default) and idColumn = 1 with 1 postItem ("Add new node"):

///    Column 0           Column 1
///
///  - Scene
///    |- ViewNode        vtkMRMLViewNode1
///    |- CameraNode      vtkMRMLCameraNode1
///    ...
///    |- my_volume.nrrd  vtkMRMLScalarVolumeNode1
///    |- Add new node
/// 

More columns can be added by setting the column index of the different columns: name, id, checkable, visibility, toolTip, extraItem and the ones defined in subclasses. Subclasses must reimplement maxColumnId if they add new column properties

Pointer (as long long) of the item if it is a scene or a node.

ExtraItemsRole 

Map (QMap<QString, QVariant>) for parent items of extra items.

VisibilityRole 

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

Property Documentation

◆ checkableColumn

int qMRMLSceneModel::checkableColumn
readwrite

Control in which column vtkMRMLNode::Selected are displayed (Qt::CheckStateRole). A value of -1 hides it. Hidden by default (value of -1).

Definition at line 86 of file qMRMLSceneModel.h.

Definition at line 83 of file qMRMLSceneModel.h.

◆ lazyUpdate

◆ nameColumn

int qMRMLSceneModel::nameColumn

Control in which column tooltips are displayed (Qt::ToolTipRole). A value of -1 hides it. Hidden by default (value of -1).

Definition at line 92 of file qMRMLSceneModel.h.
