Create and draw geometric shapes Because it is a painting application, the creation of shapes must be simple and flexible, and control must be given to the user and the mouse. Therefore, the implementation effect is as follows: Users only need to select the corresponding shape and drag it with the mouse on the canvas to create shapes of any size and proportion.
