[Qt-interest] setpalette

[Nicola De Filippo]

Hi,
i write in my custumo QPushButton this slot:

void MyButtion::change()
{
    QPalette palettea;
    palettea.setColor(QPalette::Button,Qt::green);
    this->setPalette(palettea);
}

 it's ok on linux, but on windows button don't change color. Why?
                 Best regards
                          Nicola
