can i set dolphin as root?

i need dolphin editor as root to edit system files. i know about nano but this is not very comfortable. is there any way to run dolphin as root?

kdesudo dolphin

it works but there are no icons for the folders or programs visible. only text (Fioldername).
In the terminal this is error : “QPixmap::scaled: Pixmap is a null pixmap”

But i can use dolphin.
