QmitkSliceNavigationListener Class Reference

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 posibility to react on changes of the currently selected timepoint or position in the world geometry.
It also offers convinient signals that are only triggered when the selected timepoint or the selected possition of the active render window have realy changed.
In order to setup this class properly the following things must be regarded: More...

Detailed Description

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 posibility to react on changes of the currently selected timepoint or position in the world geometry.
It also offers convinient signals that are only triggered when the selected timepoint or the selected possition of the active render window have realy 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.

SelectedPositionChanged

void QmitkSliceNavigationListener::SelectedPositionChanged ( const mitk::Point3D &  newPoint )

signal

Convinience signal that can be used if you are only interested in changes of the current selected position. Changes in time will be ignored.

SelectedTimePointChanged

void QmitkSliceNavigationListener::SelectedTimePointChanged ( const mitk::TimePointType &  newTimePoint )

signal

Convinience signal that can be used if you are only interested in changes of the current selected time point. Changes in spatial position will be ignored.

SliceChanged

void QmitkSliceNavigationListener::SliceChanged ( )

signal

Signal triggered as soon as there is any change. It may be a change in the position/slice or of the selected timepoint.
