Helper class to allow QmitkAbstractView and derived classes to react on changes of the slice/time navigation. Purpose of the class to be used in view and to give the respective view class (by composition) the possibility to react on changes of the currently selected timepoint or position in the world geometry.
It also offers convenient signals that are only triggered when the selected timepoint or the selected position of the active render window have really changed.
In order to setup this class properly the following things must be regarded:

Helper class to allow QmitkAbstractView and derived classes to react on changes of the slice/time navigation. Purpose of the class to be used in view and to give the respective view class (by composition) the possibility to react on changes of the currently selected timepoint or position in the world geometry.
It also offers convenient signals that are only triggered when the selected timepoint or the selected position of the active render window have really changed.
In order to setup this class properly the following things must be regarded:
- View class must also derive public from mitk::IRenderWindowPartListener
View class must implement void RenderWindowPartActivated(mitk::IRenderWindowPart* renderWindowPart) and pass the renderWindowPart to the listener.
void QmitkMyView::RenderWindowPartActivated(mitk::IRenderWindowPart* renderWindowPart) { this->m_SliceNavigationListener.RenderWindowPartActivated(renderWindowPart); }
View class must implement void RenderWindowPartDeactivated(mitk::IRenderWindowPart* renderWindowPart) and pass the renderWindowPart to the listener.
void QmitkMyView::RenderWindowPartDeactivated(mitk::IRenderWindowPart* renderWindowPart) { this->m_SliceNavigationListener.RenderWindowPartDeactivated(renderWindowPart); }
View class must pass its on render window part in its CreateQtPartControl(QWidget* parent)
this->m_SliceNavigationListener.RenderWindowPartActivated(this->GetRenderWindowPart());
- View class must connect the SliceChanged signal of the listener as see fit.
