 * @class QmitkSingleNodeSelectionWidget
 * @brief Widget that represents a node selection of (max) one node. It acts like a button. Clicking on it
 *        allows to change the selection.
+*
+* @remark This class provides a public function 'SetAutoSelectNewNodes' that can be used to enable
+*         the auto selection mode (default is false).
+*         The user of this class calling this function has to make sure that the base-class Q_SIGNAL
+*         'CurrentSelectionChanged', which will be emitted by this function, is already
+*         connected to a receiving slot, if the initial valid auto selection should not get lost.
