Archived:Creating Tic-Tac-Toe using QWidgets

Qt Quick should be used for all UI development on mobile devices. The approach described in this article (based on QWidget) is deprecated.

This article demonstrates how to create a simple tic-tac-toe game using QWidgets. The game rules are well known and the implementation is self-explanatory - hence these are not explained here.
