QComboBox become really different. What happens? How to use regular QComboBox on dark background?

I am using Qt 5.5 without QML.

Solution

  • You have to set it to the main window only

    yourWindow->setStyleSheet("{background-color: #HexNumber}");

    or tell the QComboBox to not have style: yourWindow->setStyleSheet("QComboBox{background-color:none}");

    or

    yourWindow->setStyleSheet("QComboBox#ComboName{background-color:none}");
