pygame系列_游戏窗口显示策略

在这篇blog中，我将给出一个demo演示：

当我们按下键盘的‘f’键的时候，演示的窗口会切换到全屏显示和默认显示两种显示模式

并且在后台我们可以看到相关的信息输出:

上面给出了一个简单的例子，当然在pygame的官方文档中有对显示策略的更权威的说明：

http://www.pygame.org/docs/ref/display.html#pygame.display.set_mode

'''
   pygame.FULLSCREEN    create a fullscreen display
   pygame.DOUBLEBUF     recommended for HWSURFACE or OPENGL
   pygame.HWSURFACE     hardware accelerated, only in FULLSCREEN
   pygame.OPENGL        create an opengl renderable display
   pygame.RESIZABLE     display window should be sizeable
   pygame.NOFRAME       display window will have no border or controls
'''
