        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.

                      So now it looks much better:

                      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.drawRoundedRect(0, 0, width(), height(), 100, 100);

                        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.
