Hello Hortense,
To achieve that, I drew inspiration from MITK's "Image Navigator" plugin
(org.mitk.gui.qt.imagenavigator).
I made my plugin's class inherit from "mitk::IRenderWindowPartListener"
(class PluginClass : public QmitkAbstractView, public
mitk::IRenderWindowPartListener)
To implement this interface you'll need to create both method stubs :
void RenderWindowPartDeactivated(mitk::IRenderWindowPart *);
void RenderWindowPartActivated(mitk::IRenderWindowPart *);
You'll also need a "Refetch()" slot (from Qt), which is the one to receive
"slice changed" event.
On "PartActivated", you'll set-up connections :
> if ( !renderWindowPart )
> return;
> QmitkRenderWindow* renderWindow =
> renderWindowPart->GetQmitkRenderWindow("axial");
> if (!renderWindow)
> return;
> m_SNC = renderWindow->GetSliceNavigationController();
> m_Adapter = new QmitkStepperAdapter(this,
> m_SNC->GetSlice(),
> "sliceNavigatorAxialFromSimpleExample"); // don't know if the name really
> matters.
>
> connect(m_Adapter, SIGNAL(Refetch()), this, SLOT(Refetch()));
On "PartDeactivated", you'll need to remove connections, delete objects,
etc.
Fun part : it is inverted for the slice number. To find it, you had to dig
inside "QmitkSliderNavigatorWidget".
Resulting in :
unsigned int numSlice = m_Stepper->GetSteps()-1u-m_Stepper->GetPos();
Good luck,
Pierre-Yves Menguy.
