Introduction

A few month ago I started designing a game. As I love the facilities Qt provides (slots & signals, the Graphics View...), I wanted to use it for designing the game. So, I started to code the game and soon I found a few limitations to Qt :

• It is not possible to change the resolution of the screen
• It is difficult to have fullscreen display under Windows, Linux and MacOS

As I knew SDL had such features, I thought that maybe I could mix Qt and SDL in order to have Signals & Slots, resolution management and fullscreen display.

The principle

What is needed :

• a main loop that will refresh the display, manage events...
• functions to display things on the screen

In order to be able to use QTimer and Qt classes, I needed to use the Qt main loop, what I did with the : QCoreApplication class.

The files

You can download the zip from here : File:Qt SDL.zip

main.cpp : It creates a QCoreApplication instance, initializes the main class GameEngine, and starts running the main loop.

qGameEngine : Initialize SDL. Calls the drawing methods.

Compiling the application
