Remove border lines from QFrame & QTabWidget

Question

Please have a look at the attached image to understand the problem. In the image you can see, how can I remove the border lines or set their color to the QDialog color. Thanks.

Answer 1

Try setting the QTabWidget Stylesheet to have 0 border.

So for instance:

tabwidget.setStyleSheet("QTabWidget::pane { border: 0; }");

using qt designer, click on the frame, go to property name stylesheet type border:0
