sudo cp ~/Download/fonts /usr/share/fonts via nautilus how to give password in gui

[Abhishek Dixit]

I want to know if I am installing fonts on command line as follows
sudo cp -rv  ~/Download/fonts /usr/share/fonts/truetype
and I am having nautilus window ~/Download/fonts open is there a way I
can copy using gui itself.
Because when I try to do so it simply denies permission to me and I am
forced to use command line.
So is there a hack for using gui in this case?
