    What do you mean to use 2 images? The concept is to display user avatar when he signed in. So it will change dynamically.

    One that is normal
    and one where you have drawn the highlight/circle on.
    and when you select/click QLabel you switch to that image.

          Ok, then painting yourself seems better :)
          What was wrong with the paintEvent + scaled + drawEllipse ?
          since you are now looking into masks

            I draws the image but not rounds it.

            void AccountImage::paintEvent(QPaintEvent *event)
            {
                QPixmap pixmap(":/Icon/default_avatar.png");
                QPixmap scaled = pixmap.scaled(width(), height(), Qt::KeepAspectRatio, Qt::SmoothTransformation);
                QBrush brush(scaled);
                QPainter painter(this);
                painter.setRenderHint(QPainter::Antialiasing);
                painter.setBrush(brush);
                painter.drawPixmap(0, 0, scaled);
                QLabel::paintEvent(event);
            }

              Why not ?
              just need the
              painter.drawEllipse(0, 0, scaled.width(), scaled.height());
              after
              painter.drawPixmap(0, 0, scaled);

                drawPixmap is draws the pixmap, not circle. What method I should use to get image circle?

                    Code:

                    void AccountImage::paintEvent(QPaintEvent *event)
                    {
                        QPixmap pixmap(":/Icon/default_avatar.png");
                        QPixmap scaled = pixmap.scaled(width(), height(), Qt::KeepAspectRatio, Qt::SmoothTransformation);
                        QBrush brush(scaled);
                        QPainter painter(this);
                        painter.setRenderHint(QPainter::Antialiasing);
                        painter.setBrush(brush);
                        painter.drawPixmap(0, 0, scaled);
                        painter.drawEllipse(0, 0, scaled.width(), scaled.height());
                        QLabel::paintEvent(event);
                    }
                    

                    0_1517062687531_2018-01-27_161733.png

                    Still image is not fully in a circle.

                    Update:
                    It looks better here:

                    0_1517062937546_2018-01-27_162205.png

                    void AccountImage::paintEvent(QPaintEvent *event)
                    {
                        QPixmap pixmap(":/Icon/default_avatar.png");
                        QBrush brush(pixmap);
                        QPainter painter(this);
                        painter.setRenderHint(QPainter::Antialiasing);
                        painter.setBrush(brush);
                        painter.drawRoundedRect(0, 0, width(), height(), 100, 100);
                        QLabel::paintEvent(event);
                    }
                    

                    But I can't scale it properly.

                      Hi
                      well can scale the image to less that the size of the
                      QLabel so there are room to draw a circle around the image.
                      Since the image is the size of the Label , you cant draw outside the image.

                      so either make image smaller to it can be inside circle or
                      make image smaller so it fits in circle.

                          Ah yes. Like brush.
                          So you want image to be inside the circle and let it clip anything else.
                          I thought you wanted to paint a circle on it. :)

                            So finally I have set it properly and it works great!

                            void AccountImage::paintEvent(QPaintEvent *event)
                            {
                                QPixmap pixmap(":/Icon/my_avatar.png");
                                QPixmap scaled = pixmap.scaled(width(), height(), Qt::KeepAspectRatioByExpanding, Qt::SmoothTransformation);
                                QBrush brush(scaled);
                                QPainter painter(this);
                                painter.setRenderHint(QPainter::Antialiasing);
                                painter.setBrush(brush);
                                painter.drawRoundedRect(0, 0, width(), height(), 100, 100);
                                QLabel::paintEvent(event);
                            }
                            

                            Result:

                            0_1517065826536_2018-01-27_171006.png

                            Thank you for the help.
