Styling tab background in QTabWidget

[mbnoimi]

As you can see in this screenshot I styled QTabWidget but I couldn't set tab's background to transparent although I used:

[code]QTabWidget#tabWidget_sidebar {
background-color: rgba(255, 255, 255, 0);
}[/code]

How can I fix this issue?

The complete QSS of QTabWidget:
[code]QMainWindow#MainWindow {
background-image: url(:/theme/bg.jpg);
}

QWidget#centralWidget {
background-color: rgba(255, 255, 255, 0);
}
/**************** SIDE BAR ****************/
QTabWidget#tabWidget_sidebar {
background-color: rgba(255, 255, 255, 0);
}

QTabWidget#tabWidget_sidebar::tab-bar {
alignment: center;
}

QTabWidget#tabWidget_sidebar::pane {
background-color: rgb(255, 255, 255, 0);
}

QTabBar::tab {
background-color: rgb(0, 0, 0, 0);
padding: 2px;
border: 2px;
text-align: center;
height: 64px;
width: 64px;
}

QTabBar::tab:selected {
background-color: rgba(255, 255, 255, 100);
}

QTabBar::tab:hover {
background-color: rgba(255, 255, 255, 150);
}
[/code]

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)");
@

It make all tabs appears white instead of transparent!

[mbnoimi]

BTW, I tried to use this but I got same result (white tabs's background)!

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

[SGaist]

add

@stack->setAttribute(Qt::WA_TranslucentBackground);@

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.

[SGaist]

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 ?
