void LogWidget::initStyle()
{
    QString styleString = "QTabWidget {"
                          " background-color: #302c3a4a;"
                          " color: #ffffff;"
                          "};"
                          "QTabWidget QPlainTextEdit {"
                          " background-color: transparent;"
                          " color: #ffffff;"
                          "}";
    setStyleSheet(styleString);
}

LogWidget::LogWidget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::LogWidget)
{
    ui->setupUi(this);
    initStyle();
}

I am facing issues with the tab switching being stuck. I find the background color of QTabWidget will change from default black to #302c3a4a if I call this function when switch tabs. How to set the background color of the QTabWidget always be #302c3a4a ？

Here is an example of how to style QTabWidget

• https://doc.qt.io/qt-6/stylesheet-examples.html#customizing-qtabwidget-and-qtabbar

I think the background changes when you switch the tabs because you show a widget with doesnt have your background color.

Thank you for your reply.I found the cause through the vetting process. QTabWidget doesn't seem to support setting ARGB colors, as I had problems with #302c3a4a colors, but other colors like red or #ff0000 worked fine.
