Detailed Description

Subject hierarchy folder plugin.

Supports folder items in subject hierarchy
Supports node hierarchies in subject hierarchy by adding folder items for the intermediate nodes. Handled cases

Scene changes

Hierarchy node added -> Add folder item ( folderPlugin::addNodeToSubjectHierarchy )
New parent is set to a hierarchy node (Modified event for both old and new parents) newParent.vtkMRMLHierarchyNode::ChildNodeAddedEvent(hierarchyNode) -> Set parent of item for hierarchy node to item for new parent ( folderPlugin::onMRMLHierarchyNodeChildNodeAdded )
Scene import ends -> Add each hierarchy node to subject hierarchy and resolve hierarchy on each added item ( addSupportedDataNodesToSubjectHierarchy, folderPlugin::addNodeToSubjectHierarchy, resolveHierarchyForItem )
Data node is associated to a hierarchy node dataNode.vtkMRMLNode::HierarchyModifiedEvent (Should only happen if building hierarchy programmaticaly from scratch) Remove hierarchy node's item from subject hierarchy ( folderPlugin::onDataNodeAssociatedToHierarchyNode )

Subject hierarchy changes

Item is reparented under an item with node hierarchy 1a. New parent has associated hierarchy node -> Set parent item's hierarchy node as parent of reparented item's hierarchy node ( folderPlugin::reparentItemInsideSubjectHierarchy ) 1b. Otherwise -> Set scene as parent of reparented item's hierarchy node ( folderPlugin::reparentItemInsideSubjectHierarchy )

Member Function Documentation

◆ addNodeToSubjectHierarchy()

virtual bool qSlicerSubjectHierarchyFolderPlugin::addNodeToSubjectHierarchy	(	vtkMRMLNode *	node,
		vtkIdType	parentItemID
	)

virtual

Add a node to subject hierarchy under a specified parent. This is basically a convenience function to call

See also: vtkMRMLSubjectHierarchyNode::CreateItem

Parameters

node	Node to add to subject hierarchy
parentItemID	Parent item of the added node

Returns: True if added successfully, false otherwise

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ canAddNodeToSubjectHierarchy()

virtual double qSlicerSubjectHierarchyFolderPlugin::canAddNodeToSubjectHierarchy	(	vtkMRMLNode *	node,
		vtkIdType	parentItemID = `vtkMRMLSubjectHierarchyNode::INVALID_ITEM_ID`
	)		const

virtual

Determines if a data node can be placed in the hierarchy using the actual plugin, and gets a confidence value for a certain MRML node (usually the type and possibly attributes are checked).

Parameters

node	Node to be added to the hierarchy
parentItemID	Prospective parent of the node to add. Default value is invalid. In that case the parent will be ignored, the confidence numbers are got based on the to-be child node alone.

Returns: Floating point confidence number between 0 and 1, where 0 means that the plugin cannot handle the node, and 1 means that the plugin is the only one that can handle the node (by node type or identifier attribute)

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ canOwnSubjectHierarchyItem()

virtual double qSlicerSubjectHierarchyFolderPlugin::canOwnSubjectHierarchyItem ( vtkIdType itemID ) const

virtual

Determines if the actual plugin can handle a subject hierarchy item. The plugin with the highest confidence number will "own" the item in the subject hierarchy (set icon, tooltip, set context menu etc.)

Parameters

item	Item to handle in the subject hierarchy tree

Returns: Floating point confidence number between 0 and 1, where 0 means that the plugin cannot handle the item, and 1 means that the plugin is the only one that can handle the item (by node type or identifier attribute)

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ canReparentItemInsideSubjectHierarchy()

virtual double qSlicerSubjectHierarchyFolderPlugin::canReparentItemInsideSubjectHierarchy	(	vtkIdType	itemID,
		vtkIdType	parentItemID
	)		const

virtual

Determines if a subject hierarchy item can be reparented in the hierarchy using the current plugin, and gets a confidence value for the reparented item. Most plugins do not perform steps additional to the default, so the default implementation returns a 0 confidence value, which can be overridden in plugins that do handle special cases.

Parameters

itemID	Item to be reparented in the hierarchy
parentItemID	Prospective parent of the item to reparent.

Returns: Floating point confidence number between 0 and 1, where 0 means that the plugin cannot handle the item, and 1 means that the plugin is the only one that can handle the item

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ createFolderUnderCurrentNode

void qSlicerSubjectHierarchyFolderPlugin::createFolderUnderCurrentNode ( )

protectedslot

Create folder node under current node.

◆ createFolderUnderItem()

Q_INVOKABLE vtkIdType qSlicerSubjectHierarchyFolderPlugin::createFolderUnderItem ( vtkIdType parentItemID )

Create folder under specified item

Parameters

parentNode Parent item for folder to create

◆ createFolderUnderScene

void qSlicerSubjectHierarchyFolderPlugin::createFolderUnderScene ( )

protectedslot

Create folder node under the scene.

◆ editProperties()

virtual void qSlicerSubjectHierarchyFolderPlugin::editProperties ( vtkIdType itemID )

virtual

Open module belonging to item and set inputs in opened module.

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ hierarchyNodeForItem()

Q_INVOKABLE vtkMRMLHierarchyNode* qSlicerSubjectHierarchyFolderPlugin::hierarchyNodeForItem ( vtkIdType itemID )

Get hierarchy node for subject hierarchy item. The item can be associated directly to a hierarchy node (if it's an intermediate hierarchy node), or it can be associated to a data node that is associated to a hierarchy node.

Returns: The hierarchy node associated to the item either directly or indirectly. NULL otherwise

◆ icon()

virtual QIcon qSlicerSubjectHierarchyFolderPlugin::icon ( vtkIdType itemID )

virtual

Get icon of an owned subject hierarchy item

Returns: Icon to set, NULL if nothing to set

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ itemContextMenuActions()

virtual QList<QAction*> qSlicerSubjectHierarchyFolderPlugin::itemContextMenuActions ( ) const

virtual

Get item context menu item actions to add to tree view.

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ itemForHierarchyNode()

Q_INVOKABLE vtkIdType qSlicerSubjectHierarchyFolderPlugin::itemForHierarchyNode ( vtkMRMLHierarchyNode * hierarchyNode )

Get subject hierarchy item for a hierarchy node. The item can be associated directly to a hierarchy node (if it's an intermediate hierarchy node), or it can be associated to a data node that is associated to a hierarchy node.

Returns: ID of the item associated to the hierarchy node directly or indirectly. Invalid ID otherwise.

◆ onDataNodeAssociatedToHierarchyNode

void qSlicerSubjectHierarchyFolderPlugin::onDataNodeAssociatedToHierarchyNode ( vtkObject * dataNodeObject )

slot

Called when hierarchy modified event is invoked for a data node Ensures that if a hierarchy node gets associated to a data node, then the item for the hierarchy node is removed from subject hierarchy (the logic implemented in the folder plugin handles data nodes with hierarchy nodes)

◆ onHierarchyNodeChildNodeAdded

void qSlicerSubjectHierarchyFolderPlugin::onHierarchyNodeChildNodeAdded	(	vtkObject *	parentNodeObject,
		vtkObject *	childNodeObject
	)

protectedslot

Called when child node was added to hierarchy node Ensures that the hierarchy specified by node hierarchies are mirrored in subject hierarchy

◆ reparentItemInsideSubjectHierarchy()

		vtkIdType	parentItemID
	)

virtual

Reparent an item that was already in the subject hierarchy under a new parent.

Returns: True if reparented successfully, false otherwise

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ resolveHierarchies()

Q_INVOKABLE bool qSlicerSubjectHierarchyFolderPlugin::resolveHierarchies ( )

Resolve all node hierarchy items in the scene. Traverses scene for hierarchy nodes, and makes sure the same parents are set in subject hierarchy

◆ resolveHierarchyForItem()

Q_INVOKABLE bool qSlicerSubjectHierarchyFolderPlugin::resolveHierarchyForItem ( vtkIdType itemID )

Add the item for the hierarchy node to the proper place in subject hierarchy. If the parent node hierarchy item does not exist yet, add that too, all the way to the scene

◆ roleForPlugin()

virtual Q_INVOKABLE const QString qSlicerSubjectHierarchyFolderPlugin::roleForPlugin ( ) const

virtual

Get role that the plugin assigns to the subject hierarchy item. Each plugin should provide only one role.

Reimplemented from qSlicerSubjectHierarchyAbstractPlugin.

◆ sceneContextMenuActions()

virtual QList<QAction*> qSlicerSubjectHierarchyFolderPlugin::sceneContextMenuActions ( ) const

virtual

Get scene context menu item actions to add to tree view Separate method is needed for the scene, as its actions are set to the tree by a different method
