    Description

      If the QStyleHints::setFocusOnTouchRelease value is "true" and the combobox widget no focus, then it can't popup on mouse release.

      See code:

          QFontComboBox *box = new QFontComboBox();
    box->setEditable(false);
    box->setFocusPolicy(Qt::NoFocus);
    box->show();

      Copy form https://github.com/qt/qtbase/blob/dev/src/widgets/widgets/qcombobox.cpp#L3288 :

      // Why "&& hasFocus()" in mouseReleaseEvent？
void QComboBox::mouseReleaseEvent(QMouseEvent *e)
{
    Q_D(QComboBox);
    d->updateArrow(QStyle::State_None);
    if (QGuiApplication::styleHints()->setFocusOnTouchRelease() && hasFocus())
        d->showPopupFromMouseEvent(e);
}

      Is this a bug？
