void QmitkNodeDescriptorManager::AddDescriptor ( QmitkNodeDescriptor *  _Descriptor )

Adds a new descriptor to the manager. The manager takes the ownership.

QList< QAction * > QmitkNodeDescriptorManager::GetActions ( const mitk::DataNode *  _Node ) const

Returns a list of all actions that are associated with the given node. If there are more than one Descriptors for this node all actions will be merged together. E.g. all actions from the "unknown" DataNodes will be added to this list. Generic Actions like Save, Load, etc. are stored there.

QmitkNodeDescriptor * QmitkNodeDescriptorManager::GetDescriptor ( const mitk::DataNode *  _Node ) const

Get the last descriptor in the descriptors list that matches the given node. Attention*: More specialized Descriptors should therefore be appended at the end of the list, e.g. first add "Image", then add "Image Mask"

Returns:
a QmitkNodeDescriptor for the given node or a QmitkNodeDescriptor describing unknown nodes (never 0)
