Hello all Qt developers:
I used a comboBox on my Application , I want make its popup List translucent or transparent , But I don't know the way .
My Qt version: 4.4.0 my Os ebian Linux , WIN-CE , Thanks for you suggestion .

NOTE:
I read the source code of the QComboBox , and I found there was a QComboPrivateContainer *container behind the QAbstractItemView object of the popup (/*the popup*/ QComboBox::view());
The style of the QAbstractItemView can be set by "setStyleSheet("background-color: rgba(0,0,0,0);")" ,but the style of the container can't be set by this way , It can be set by"QComboBox::view()->parentWidgetOpacity(0.5)" , but I can't use this , because the WIN-CE doesn't support this .
