QComboBox: shadow effect of drop-down/popup removable?

PatrickS

Hi guys,

I would like to remove the shadow effect of a QComboBox' drop-down / popup, but nothing worked yet.

Setting the combo box a different style via

myComboBox->setStyle(QStyleFactory::create("Windows"));

was not successful. The available styles on my MS Windows 7 machine are "Windows", "WindowsXP", "WindowsVista" and "Fusion" - I tried them all.

I am using Qt 5.5.1.

Any ideas?
A CSS solution would be superior, but I am grateful for any suggestion.
Thanks in advance!

@PatrickS
this a platform feature. Windows (or at least Qt under Windows) adds it for popup windows.
Try this pls (before showing the popup):

comboBox->view()->window()->setWindowFlags( Qt::Popup | Qt::FramelessWindowHint | Qt::NoDropShadowWindowHint );

Great, that worked! Thank you very much!
