QColorDialog will not set the options i choose.

In the standdialogs example with code

qDebug() << colorDialogOptionsWidget->value();
const QColorDialog::ColorDialogOptions options = QFlag(colorDialogOptionsWidget->value());
const QColor color = QColorDialog::getColor(Qt::green, this, "Select Color", options);

and “do not use native dialog” option unchecked, i get this colordialog and the output of 0

With the same EXACT code in my application

QColorDialog::ColorDialogOptions options = QFlag(0);
QColor color = QColorDialog::getColor(Qt::green, this, "Select Color", options);

even if i put

QFlag(QColorDialog::NoButtons, QColorDialog::ShowAlphaChannel)

i always get this non native dialog:
