Title bar buttons doesn't work on Win7.



  • Hello.

    I have a strange problem with my Qt app. It's a simple QtWidgets app. I need it to be fixed size so in the constructor of the QMainWindow class I put this:

    setFixedSize(700, 487);
    

    It works as expected, but I tested it on some other pc and I found that on Win7 system the title bar buttons (minimize, close) doestn't work, like they were blocked. On Win10 works normally. Have anyone had this problem before?

    Thanks.



  • Hi, if you're using Qt 5.13.1 it could be this bug



  • Thanks, it describes exactly my issue, I updated Qt to 5.14.2 but the buttons still don't work.
