Implementing a chess game

At this point, you are ready to employ your newly gained skills in rendering graphics with Qt to create a game that uses widgets with custom graphics. The hero of today will be chess and other chess-like games.

Time for action – Developing the game architecture

Create a new Qt Widgets Application project. After the project infrastructure is ready, choose New File or Project from the File menu and choose to create a C++ Class. Call the new class ChessBoard and set QObject as its base class. Repeat the process to create a ChessAlgorithm class derived from QObject and another one called ChessView, but choose QWidget as the base class this time. You should end up with a file named main.cpp and four classes:

• MainWindow will be our main window class that contains a ChessView
• ChessView will be the widget that displays our chess board
• ChessAlgorithm will contain the game logic
• ChessBoard will hold the state of the chess board and provide it to ChessView and ChessAlgorithm
