C++ Programming By Example - Allow for Shape Resizing

The video tutorial covers the implementation of shape resizing in a painting application using QPainter. It begins with an introduction to the task, followed by a detailed explanation of the solution, including the use of structures for circles and squares, handling mouse events, and updating the drawing in real-time. The course concludes with a summary of topics covered, such as C syntax, data structures, and QT5 framework.

What is the significance of the center point when drawing a circle?

How is the radius of the circle calculated during the drawing process?

What happens in the mouse release event when drawing shapes?

Summarize the overall changes made to the painting application to enable shape resizing.
