Qt/C++/CSS: QTooltip stylesheet background colour

  • Hi there,

    I've recently come across a problem developing for the Windows platform, relating to Windows own 'themes'. I have been developing a program with Windows Basic display but upon running the program with a Theme enabled (e.g. Windows Aero), my QTooltips change their background colour, even though the font colour remains correct.

    I have linked my stylesheets which work 100% in Basic mode where I declare how to display the QTooltip:
    color: #8f8;
    background-color: #222;

    The background colour when using a Windows theme simply remains white. I have tried declaring this code within my C++ application, both directly before AND after objects are created to no avail. Using a separate .css file and loading the stylesheet to the parent window also doesn't seem to affect the background-colour. I have been looking around for a solution for some time now (returning to the problem on occasion for the last few months) but have not come across anyone with a similar issue.

    Any help would be highly appreciated.

    Kind Regards,

  • I try your QSS on Linux with KDE and I think that on KDE is similar situation. I found an "old bug with code":https://bugreports.qt-project.org/browse/QTBUG-2849. On my system when I add to QToolTip QSS
    border-style: none;
    /* border-style: outset; works too */
    then backgorund-color starts working. Maybe this will help you.
