      Is your QTabWidget contained in another widget ? And what do you expect to see through it (i.e. desktop, other program window etc...) ?

        It contained in MainWindow directly.

        As shown in the screenshot I expect to see transparent tab (see the wood instead of gray color)

          Then try this:

          @
          QStackedWidget *stack = tabWidget->findChild<QStackedWidget *>();
          stack->setStyleSheet("background-color: rgba(255, 255, 255, 0)");
          @

              [code]stack->setStyleSheet("background-color: rgba(0, 0, 0, 0)");[/code]

                    I created a repository contains on demo application for testing QTabWidget stylesheet and I added you as a moderator: https://github.com/mbnoimi/test

                    May you please see what's going on?

                      Your example is missing the stylesheet/background/icons to reproduce what you show in your first post.

                        It doesn't missing anything. I created very simple project so may you please run the project to test your suggestions.

                          If you'd like me to test anything related to your widget styling problem, I'll need a complete example with the style sheet your are using and the necessary elements for it (i.e. the background / icons)

                            OK; I updated a new version with resources (modified the screenshot)

                                Then... The first question that should have been asked: What version of Qt/OS are you using ?

                                    I have tested it on Windows and can confirm that it's not working on it (though it does on OS X)

                                    Did you check the "bug report system":https://bugreports.qt-project.org/ to see if this is something known ? You might consider creating a bug report (put as much details as you can and a minimal compilable example so it can be reproduced)
