write by 九天雁翎(JTianLing) -- blog.csdn.net/vagrxie 前一篇文章 讲了SDL的除video以外的大部分模块.本文主要关注SDL的video模块部分. SDL中的video模块包含了大部分与平台相关的代码,并且SDL处理的很有技巧性,这里利用C语言的函数指针来模拟了一种类似于面向对象的效果.主要的关键点在SDL_VideoDevice *current_video = NULL;这一句定义的全局变量current_video上,我们先来看看这个变量类型…

1. BitBlt 我想做Windows开发应该都知道这个API, 它能实现DC间的内容拷贝, 如果我们把源DC指定成Monitor DC或是桌面DC, 它就能实现抓屏功能. 对于通过这种方式的抓屏, 有2点需要特别提醒: a. 在XP下我们可以通过最后的拷贝标志来控制是否拷贝layered window, 只有SRCCPY表示拷贝内容不包含layered window, 如果是SRCCPY | CAPTUREBLT表示拷贝包括Layered window在内的所有窗口. 这个标志在Vista之…

先看下面代码: #include <stdio.h> #include <windows.h> #include <memory> class Test { public: Test(int i) :a(i) { } ~Test() { } public: void Print() { printf("a=%d\n", a); } private: int a; }; int main() { std::shared_ptr<Test>…
