How to style QTabBar close button

Is there a way to assign CS开发者_StackOverflow中文版S style for the QTabBar close button? Normally QTabBar can be styled, but I can't find its how button can be referenced from CSS.

As noted in a comment above, since Qt 4.6 you can use following style:

 QTabBar::close-button {
     image: url(close.png);
     subcontrol-position: left;
 }

It seems like there is not currently a way to style the close button via Qt style sheets. Not only is it not documented, there doesn't seem to be a style for it in src/gui/styles/qstylesheetstyle.cpp.

You can set the button using QTabBar::setTabButton() method.

You may want to submit it as a feature request on the Qt Bug Tracker.
