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

Member Enumeration Documentation

ItemDataRole

enum qMRMLSceneModel::ItemDataRole

Enumerator
UIDRole	Unique ID of the item. For nodes, it is the node ID.
PointerRole	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.
LastRole	Must stay the last enum in the list.

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.

extraItemColumn

int qMRMLSceneModel::extraItemColumn

readwrite

Control in which column the extra items are displayed A value of -1 hides it (not tested). 0 by default

Definition at line 95 of file qMRMLSceneModel.h.

idColumn

int qMRMLSceneModel::idColumn

readwrite

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

Definition at line 83 of file qMRMLSceneModel.h.

lazyUpdate

bool qMRMLSceneModel::lazyUpdate

readwrite

Control whether the model actively listens to the scene. If LazyUpdate is true, the model ignores added node events when the scene is importing/restoring, but synchronize with the scene once its imported/restored.

Definition at line 75 of file qMRMLSceneModel.h.

listenNodeModifiedEvent

NodeTypes qMRMLSceneModel::listenNodeModifiedEvent

readwrite

This property controls whether to observe or not the modified event of the node and update the node item data accordingly. It can be useful when the modified property is displayed (name, id, visibility...) OnlyVisibleNodes by default

Definition at line 69 of file qMRMLSceneModel.h.

nameColumn

int qMRMLSceneModel::nameColumn

readwrite

Control in which column vtkMRMLNode names are displayed (Qt::DisplayRole). 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 80 of file qMRMLSceneModel.h.

toolTipNameColumn

int qMRMLSceneModel::toolTipNameColumn

readwrite

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.

visibilityColumn

int qMRMLSceneModel::visibilityColumn

readwrite

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