    Hi
    Is there possible to set QTabWidget background transparent (same as the form background)?
    I tried this in the main.cpp but nothing has changed, I got a white background:
    @
    QPalette q= form.widget.tab->palette();
    form.widget.tab->setPalette(q);
    form.widget.tab->setStyleSheet("background-color: rgba( 255, 255, 255, 0% );" );
    @
    What I'm doing wrong?
    Is there possible to write it in the qss file?

    Thank you for your help!!!!

    Massi

    [Edit: Please be sure and wrap your code in @ blocks; mlong]

      Hai,Massinissa.
      Try to use this command.It gives the solution for your problem.

      @
      QPalette palette = view->palette();
      palette.setBrush(QPalette::Base, Qt::transparent);
      view->page()->setPalette(palette);
      view->setAttribute(Qt::WA_OpaquePaintEvent, false);
      @

        Hi

        Try replacing this:
        @
        "background-color: rgba( 255, 255, 255, 0% );"
        @
        with this one:
        @
        "background: transparent;"
        @
