OSX - QMenu vs QWidgetAction paints with transparent bg

Hi

Some reason below code paints a menu with transparent background. So the check box and label next to it has no background.

Any ideas why ?

Code:

---

QMenu *menuOther = new QMenu(tr("&Other"), this);
 
    QCheckBox *checkbox = new QCheckBox(tr("Test"), this);
    connect(checkbox, SIGNAL(toggled(bool)), parent, SLOT(button(bool)));
 
    QWidgetAction *action = new QWidgetAction(menuOther);
    action->setDefaultWidget(checkbox);
 
    menuOther->addAction(action);   
    addMenu(menuOther);

Thanks for looking

Check parent style, maybe it has transparent background set.

I don't set styling anywhere.

I have the same set Else where, QMenu inside QMenu but I don't use checkboxes there with QWidgetAction. The QWidgetAction causes this transparency but no idea how to fix it.

Looks like a bug. But what is the hack to fix it ?

I use QT 4.7.4 no idea what is the carbon vesion.
