QTabBar one color line can't be changed

[Alundra]

Hi all,
There is one line who can't be changed with stylesheet :

It's like Qt compute it and you can't change.
It's the long line on the bottom after tabs.
If a solution exists should be nice to say.
Thanks for the help

Try this, it's working for me...

QTabWidget::pane { border-top: 2px solid red;}

QTabWidget::pane { border-top: 2px solid red;}

No change, the line still "silver" color, it's when I move one dock on one another dock, that makes a tab and this line is here...

It seems that you need to share your code to get more idea about it...

Move the "Left" dock on the "Right" dock and you will see the line is not red.
Minimal code who reproduces the bug :

#include <QApplication>
#include <QMainWindow>
#include <QDockWidget>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    a.setStyleSheet("QTabWidget::pane{ border-top: 2px solid red;}");
    QMainWindow w;
    w.addDockWidget(Qt::LeftDockWidgetArea,new QDockWidget("Left",&w));
    w.addDockWidget(Qt::RightDockWidgetArea,new QDockWidget("Right",&w));
    w.show();
    return a.exec();
}

#include <QApplication>
#include <QMainWindow>
#include <QDockWidget>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    a.setStyleSheet("QTabWidget::pane{ border-top: 2px solid red;}");
    QMainWindow w;
    w.addDockWidget(Qt::LeftDockWidgetArea,new QDockWidget("Left",&w));
    w.addDockWidget(Qt::RightDockWidgetArea,new QDockWidget("Right",&w));
    w.show();
    return a.exec();
}
