    Default Style Sheets: Change font-style in QComboBox but not in corresponding popup

    Depending on some dynamic property, I'd like to set the font style in the top-item of a QComboBox to italic, but keep the appearance of the items in the corresponding popup (QListView).

    I tried it with the following qss:

    Qt Code:
    1. QComboBox#librarySettingsBox QListView {
    2. font-style: normal;
    3. /* background-color: rgb(255, 255, 127);*/
    4. }
    5. QComboBox[dirty="true"] {
    6. font-style: italic;
    7. /* background-color: rgb(85, 0, 255);*/
    8. }
    To copy to clipboard, switch view to plain text mode 

    In my C++ code, I call update on the widget after setting the property like this:

    Qt Code:
    1. ui->librarySettingsBox->setProperty("dirty", dirty);
    2. ui->librarySettingsBox->style()->unpolish(ui->librarySettingsBox);
    3. ui->librarySettingsBox->style()->polish(ui->librarySettingsBox);
    4. ui->librarySettingsBox->update();
    To copy to clipboard, switch view to plain text mode 

    The "font-style: normal" setting is supposed to override the italic setting in the QListView, as it has a higher priority due to the id-tag contained. This can also be confirmed by uncommenting the "background-color" tags. However, the font-style does not seem to have any effect on the QListView. Why is it so and how can I fix it?

    QComboBox has two different parts the edit box is actually QLineEdit and then PopUp which is I think QListView(Please check this).

    Try to set different stylesheet for both the component for given QComboBox and it should work.

    see below link which gives list of state of any qt control for stylesheet...
    http://qt-project.org/doc/qt-4.8/sty...ml#paletterole

    I have tried one example in which combobox font is italics and dropdown font is normal, below is stylesheet used for that...
    QComboBox {font-style: italic;}
    QComboBox QListView { font-style: normal; }

    Unfortunately, this doesn't work. The problem doesn't seem to be with the selectors, but with applying a font-style to the QListView, as overriding styles in the QListView does work e.g. for background-colors.

    Which Version of Qt did you use for that? Maybe I should say I'm using Qt 5.2.1.
