virtual QString QmitkDataStorageComboBoxWithSelectNone::currentValue ( ) const

virtual

Get the current file path.

◆ Find()

int QmitkDataStorageComboBoxWithSelectNone::Find ( const mitk::DataNode * dataNode ) const

overridevirtual

Searches for a given node, returning the index if found.

Parameters

dataNode an mitk::DataNode, can be nullptr.

Returns: int -1 if not found, and compared to base class, will add 1 onto the retrieved index.

Reimplemented from QmitkDataStorageComboBox.

◆ GetNode()

overridevirtual

Retrieves the node at a given index, where if index is zero, will always return nullptr.

Parameters

index An integer between 0 and n = number of nodes.

Returns: mitk::DataNode::Pointer nullptr or a data node pointer.

Reimplemented from QmitkDataStorageComboBox.
