ANSWER:

I didn't mentioned that I'm adding this item to statusBar().

To remove border around the item I used:

QStatusBar::item {border: 0px;}

Answer 1

Have you tried this ?

QToolButton {  
    border: 1px solid #575757;
    border-radius: 4px;
    background-color: palette(base);
}

Usually, web best-practices recommand that if you change one color, you have to change them all.

It is likely that you will also have to change the text color as well to avoid potential issues on some computers with non-default window text color.
