Hello!

I'm trying to draw some geometric primitives on MarbleWidget using customPaint method, but the problem is that all primitives covers widgets ( https://ibb.co/mKSyAk ). Don't know how to draw all primitives under the widgets.

customPaint as described in https://techbase.kde.org/Marble/MarbleGeoPainter shows that behavior, but you can use https://techbase.kde.org/Marble/LayerInterface to specify a different so called paint layer.
