Introduction

For drawing and painting in Python, we will be making use of several classes. The most important of them is the QPainter class.

This class is used for painting. It can draw lines, rectangles, circles, and complex shapes. While drawing with QPainter, you can use the QPainter class pen to define the color of the drawing; thickness of the pen/brush; style; whether the line is drawn as solid, dotted, or dash-dot; and so on.

Several methods of the QPainter class are used in this chapter to draw different shapes. A few of them are listed here:

• QPainter::drawLine(): This method is used for drawing a line between two sets of x and y coordinates
• QPainter::drawPoints(): This method is used for drawing a point at a location specified through the supplied x and y coordinates
• QPainter::drawRect(): This method is used for drawing a rectangle between two sets of x and y coordinates...
