Example #1

File: qgraphicswidget_p.cpp Project: venkatarajasekhar/Qt

void QGraphicsWidgetPrivate::updatePalette(const QPalette &palette)
{
    Q_Q(QGraphicsWidget);
    // Update local palette setting.
    this->palette = palette;

    // Calculate new mask.
    if (q->isWindow() && !q->testAttribute(Qt::WA_WindowPropagation))

        } else {

    // Notify change.
    QEvent event(QEvent::PaletteChange);
    QApplication::sendEvent(q, &event);
}
