Qt stylesheet QPushButon example

[_franko_]

Hello everybody.

Could anyone who knows perfect stylesheets can give me a little example of setting standard icons in stylesheet on QPushbutton?

I try used something like this but this doesn't work:

QPushButton {
 font: 75 28pt \"Serif\";
 background-color: BROWN;
 icon-size: 32px;
 border-image: backward-icon;
}

QPushButton {
 font: 75 28pt \"Serif\";
 background-color: BROWN;
 icon-size: 32px;
 border-image: backward-icon;
}

To copy to clipboard, switch view to plain text mode 

First: I don't know how to use default icons from Qt in stylesheets and I'm weak with styles, so please forgive me.
Second: I want to have a button which will blinking in other color when it has a focus.
To do this I used simple method - setting background-color in stylesheet and QTimer timeout signal.
Is there are better way to achive this?

Please can somebody give me an example of using standard icons (theese from QStyle) in stylesheets?

Thank you.
Regards.
