How do C++ libraries handle graphics and interfaces?

The C function library provides a variety of graphics and interface processing tools, including: SFML (cross-platform 2D graphics and audio library): used to develop sprite-driven 2D games and media players. Qt (cross-platform graphical user interface framework): used for developing desktop applications and media players.

Use the C function library to process graphics and interfaces

The C function library provides a wide range of tools for graphics and interface processing, allowing Developers can create complex applications on a variety of platforms. The following introduces several commonly used function libraries and their practical cases:

SFML (Simple and Fast Multimedia Library)

• Function: Cross-platform 2D graphics and audio library
• Practical case:Developing sprite-based 2D games and media players

// 包含 SFML 头文件
#include <SFML/Graphics.hpp>

int main() {
    // 创建一个渲染窗口
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML 教程");

    // 创建一个精灵
    sf::Sprite sprite;
    sprite.setTexture(*sf::TextureManager::getTexture("ball.png"));

    // 游戏循环
    while (window.isOpen()) {
        // 处理事件
        sf::Event event;
        while (window.pollEvent(event)) {
            // 关闭窗口
            if (event.type == sf::Event::Closed)
                window.close();
        }

        // 清空窗口
        window.clear();

        // 绘制精灵
        window.draw(sprite);

        // 显示窗口
        window.display();
    }

    return 0;
}

Qt

• Function: Cross-platform graphical user interface framework
• Practical case: Develop desktop applications, media players

// 包含 Qt 头文件
#include <QApplication>
#include <QWidget>

int main(int argc, char *argv[]) {
    // 创建一个 Qt 应用程序
    QApplication app(argc, argv);

    // 创建一个主窗口
    QWidget window;
