Hi Stefan,

with auto-layering you mean the adjustment of the layer property in void
QmitkDataStorageTreeModel::AdjustLayerProperty(), right? In contrast to
Ingmar's way of handling layers I am not really using them because I do
not need the 2D render windows. And I also do not set the "fixedLayer".
I think in my application the auto-layering is not working because my
app is not based on the workbench but on the quick render qml example
(QmitkDataStorageTreeModel is not used). Wouldn't it make more sense to
move this functionality somewhere else? Somewhere where it is
independent of QT?

Thanks for your support.

Best

Martin
