QLabel background color doesn't work in toolbars

[iig]

Hi, all!

Why I can't set QLabel background color when it is in QToolBar?
This is my code:



#include <QtGui>
int main(int argc, char** argv)
{
QApplication app(argc,argv);
QMainWindow w;

QToolBar* bar = new QToolBar();
QLabel* label = new QLabel("TEST");

QPalette pal = label->palette();
pal.setColor(label->backgroundRole(), Qt::green);
label->setPalette(pal);
label->setAutoFillBackground(true);

bar->addWidget(label);
w.addToolBar(bar);

w.show();

app.exec();

return 0;
}


And here are result:
