Buttons - color frames

[Coder5546]

I made transparent button, but I also want to do a color frame to this button.

My code to transparent background:

setStyleSheet("background-color: rgba( 255, 255, 255, 10% );" );
setAttribute(Qt::WA_TranslucentBackground);

setStyleSheet("background-color: rgba( 255, 255, 255, 10% );" );
setAttribute(Qt::WA_TranslucentBackground);

To copy to clipboard, switch view to plain text mode 

How to make such frames ?
