Getting the Icon of a MessageBox

[thru]

Hi,

Does anyone know if it's possible getting the Icon that would be shown in a QMessageBox? (the idea is to use the qt's internal icon that you would get in a QMessage box with for example QMessageBox::Warning)

thanks!

QIcon QStyle::standardIcon ( StandardPixmap standardIcon, const QStyleOption * option = 0, const QWidget * widget = 0 )

standardIcon = QStyle::SP_MessageBoxWarning


-------

you can see internally how qmessagebox get his icon here:

QPixmap QMessageBoxPrivate::standardIcon(QMessageBox::Icon icon, QMessageBox *mb)
{
    QStyle *style = mb ? mb->style() : QApplication::style();
    int iconSize = style->pixelMetric(QStyle::PM_MessageBoxIconSize, 0, mb);
    QIcon tmpIcon;
    switch (icon) {
    case QMessageBox::Information:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxInformation, 0, mb);
        break;
    case QMessageBox::Warning:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxWarning, 0, mb);
        break;
    case QMessageBox::Critical:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxCritical, 0, mb);
        break;
    case QMessageBox::Question:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxQuestion, 0, mb);
    default:
        break;
    }
    if (!tmpIcon.isNull())
        return tmpIcon.pixmap(iconSize, iconSize);
    return QPixmap();
}

QPixmap QMessageBoxPrivate::standardIcon(QMessageBox::Icon icon, QMessageBox *mb)
{
    QStyle *style = mb ? mb->style() : QApplication::style();
    int iconSize = style->pixelMetric(QStyle::PM_MessageBoxIconSize, 0, mb);
    QIcon tmpIcon;
    switch (icon) {
    case QMessageBox::Information:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxInformation, 0, mb);
        break;
    case QMessageBox::Warning:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxWarning, 0, mb);
        break;
    case QMessageBox::Critical:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxCritical, 0, mb);
        break;
    case QMessageBox::Question:
        tmpIcon = style->standardIcon(QStyle::SP_MessageBoxQuestion, 0, mb);
    default:
        break;
    }
    if (!tmpIcon.isNull())
        return tmpIcon.pixmap(iconSize, iconSize);
    return QPixmap();
}
