* @brief This class connects different 'QmitkSynchronizedNodeSelectionWidget', such that
29
* they can synchronize their current node selection and their current selection mode.
30
*
31
* In order to synchronize a new node selection widget with other already connected
32
* node selection widgets, 'ConnectWidget(const QmitkSynchronizedNodeSelectionWidget*)' has to be used.
33
* In order to desynchronize a node selection widget,
34
* 'DisconnectWidget(const QmitkSynchronizedNodeSelectionWidget*)' has to be used.
35
* If a new node selection has been connected / synchronized,
36
* 'SynchronizeWidget(QmitkSynchronizedNodeSelectionWidget*' can be used to initialy set
37
* the current selection and the current selection mode.
38
* For this, both values are stored in this class internally.
