@Santiago_Pendon said in Slicer 3D GUI edit:
it would be great if the widget will appear on the top automatically.
AFAIK there is no way to set a position or order of QDockWidgets in some DockArea.
I think they are ordered the way they are added.
So to have your own QDockWidget on top, you have to add it before everything else, which might be tricky.
