yes it is mutually, ui_lib creates a SchematicView, which is derived
from GraphicView. SchematicView's instance is in ui_schematic_lib, where
GraphicsView is in ui_lib. Probably I should stay the files inside these
directory and add them to the source in ui_lib project as the docs
suggested.
Thanks,
Olaf
