Answer 1

Refer the below code in your paint event to draw a line in Qt.

def paintEvent(self, event):
    painter = Qt.QPainter()
    painter.begin(self)
    painter.pen().setWidth(int width)
painter.setPen(Qt.QColor(100,100,100))
    painter.drawLine(x1,y1,x2,y2)
    painter.end()
    Qt.QFrame.paintEvent(self, event)
