QLCNumber background color

[drave]

This code (on Qt 4.6)

QPalette Pal = ui->lcdNumber->palette();
Pal.setColor(QPalette::Normal, QPalette::WindowText, Qt::green);
Pal.setColor(QPalette::Normal, QPalette::Window, Qt::black);
ui->lcdNumber->setPalette(Pal);

changes the digits to green OK but has no effect on the background color, which remains light grey.

Why not ?
How can i change the background color ?

thanks

You code for the palette is fine. So try to use QWidget::autoFillBackground.

#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
 
    QWidget w;
    QLCDNumber lcd(&w);
    lcd.setAutoFillBackground(true);// see the different if you comment that line out.
 
    QPalette Pal = lcd.palette();
    Pal.setColor(QPalette::Normal, QPalette::WindowText, Qt::green);
    Pal.setColor(QPalette::Normal, QPalette::Window, Qt::black);
    lcd.setPalette(Pal);
 
 
    w.show();
 
    return app.exec();
}

#include <QtGui>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);

    QWidget w;
    QLCDNumber lcd(&w);
    lcd.setAutoFillBackground(true);// see the different if you comment that line out.

    QPalette Pal = lcd.palette();
    Pal.setColor(QPalette::Normal, QPalette::WindowText, Qt::green);
    Pal.setColor(QPalette::Normal, QPalette::Window, Qt::black);
    lcd.setPalette(Pal);


    w.show();

    return app.exec();
}
