Hi,
I have a table view and when I drop something on it, I get a blue focus inside it. Now, iTunes has the same behavior but in iTunes the color of the line is a lighter blue and the line is thicker. I have added a picture to explain it better. I want to achieve the same thing but I don't know why.

Thanks in advance
