Stylesheets and QFontComboBox Sub-control

[been_1990]

I've been trying to use a picture for the background of the "down-arrow" of QFontComboBox. If I try

QFontComboBox::arrow_down{
border:none;
 background-image: url("arrow.png" );
}

QFontComboBox::arrow_down{
border:none;
 background-image: url("arrow.png" );
}

To copy to clipboard, switch view to plain text mode 

Nothing happens. I tried that on a regular QComboBox and no image is displayed, but using gradients work fine.
The effect I want to achieve with the font combobox, is a no-border box, not even the down-arrow. Just everything plain.

Hello,

I've one question to you, ¿have you added the arrow.png file to thr resources file of the project?.
Maybe I'm wrong, but when I've tried to put an icon into a button or maybe into a menu bar, nothing has appear unless I add it into the resorurces file.

I hope that helps.
Regards.

It seems that I only needed to use :: before the sub-control I wished to configure.
