Hi Luca, sorry for the late reply, we are currently in the process of finalizing new features for the upcoming MITK release in April / Mai.
If you have an IRenderWindowPart I guess you are casting it to a an QmitkStdMultiWidgetEditor (or at least an QmitkAbstractMultiWidgetEditor), right? The QmitkAbstractMultiWidgetEditor (which is also the base class of the QmitkStdMultiWidgetEditor) provides a function to retrieve the contained QmitkAbtractMultiWidget (QmitkStdMultiWidget): - QmitkAbstractMultiWidgetEditor::GetMultiWidget() You can use this function to get the multi widget and pass it on to your QmitkMultiWidgetLayoutManager. However, we were wondering how you use the layout manager: If you already have e.g. a QmitkStdMultiWidgetEditor (because you retrieved it using e.g. QmitkAbstractView::GetRenderWindowPart and then casting it) then an instance of a QmitkStdMultiWidget can be retrieved (see paragraph above). With this QmitkStdMultiWidget you can call QmitkAbstractMultiWidget::GetMultiWidgetLayoutManager() and you will get an instance of a QmitkMultiWidgetLayoutManager. Because each QmitkAbstractMultiWidget already comes with a layout manger, see initializer list of QmitkAbstractMultiWidget::Impl::Impl. Also, you don’t need to call QmitkMultiWidgetLayoutManager::SetAll2DLeft3DRightLayout, you can also use QmitkMultiWidgetLayoutManager::SetLayoutDesign with the required argument, e.g. QmitkMultiWidgetLayoutManager::SetLayoutDesign(LayoutDesign::ALL_2D_LEFT_3D_RIGHT) Let me know if this helps.

I am trying to update the code to use IRenderWindowPart instead (as suggested by this<https://www.mitk.org/wiki/Views_Without_Multi_Widget> documentation page). My guess is that the correct way to do this now is to use QmitkMultiWidgetLayoutManager<https://docs.mitk.org/nightly/classQmitkMultiWidgetLayoutManager.html>, in particular the method SetAll2DLeft3DRightLayout, but I don’t understand how to pass the current QmitkAbstractMultiWidget to its constructor or its SetCurrentRenderWindowWidget method. Am I on the right track? If so, what would be the correct way of getting an QmitkAbstractMultiWidget object to pass to QmitkMultiWidgetLayoutManage from IRenderWindowPart?
