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.
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.
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.
