如何屏幕保护程序在Mac OS X和Linux工作？ [英] How does screen savers work on Mac OS X and Linux?

问题描述

在Windows中的屏幕保护程序仅仅是一个带有的 .scr等的扩展在system32倾倒可执行文件，并且它有三个开关控制（/ P，/ c和/ S，我认为）。

In Windows a screen saver is just an executable with a .scr extension dumped in the system32, and it is controlled with three switches (/p, /c and /s, I think).

如何屏幕保护程序在Mac OS X和Linux工作？难道他们在Mac OS X和Linux的工作同样（GNOME，KDE，Ubuntu的，或是其他地方不同的是），或者是完全不同的？

How does screen savers work on Mac OS X and Linux? Do they work similarly in Mac OS X and Linux (Gnome, KDE, Ubuntu, or wherever the difference is) or is it completely different?

此外，他们能开发在C＃/单声道？

Also, can they be developed in C#/Mono?

推荐答案

在OSX屏幕保护系统是一个屏幕保护程序（通常是，但不一定）是一个Objective- C库，扩展一个基类来实现的方法，如绘画，偏好窗格，预览模式等。

The screensaver system in OSX is that a screensaver (typically, but not necessarily) is an Objective-C library, extending a base class to implement methods such as drawing, a preference pane, a preview mode and so on.

有上写他们一个很好的教程<一个HREF =http://cocoadevcentral.com/articles/000088.php相对=nofollow>这里。

There is a good tutorial on writing them here.

虽然Objective-C的是预期的语言，它是足够简单耦合在一起的C / C ++中的Objective-C API背后的实现。

While Objective-C is the language expected, it is straightforward enough to couple together a C/C++ implementation behind the Objective-C API.

有一个API（一桥），以允许其他语言用Objective-C的API的互操作。这是用来，在这里例如， ，以允许用Python编写的OSX屏幕保护程序。我想类似的方法是可行的单

There is an API (a bridge) to allow other languages to inter-operate with Objective-C APIs. This is used, for example, here to allow OSX screen savers written in Python. I imagine a similar approach is feasible for Mono.

的xscreensaver 现发展主要在OSX，并使用OSX屏保API有和X11别的东西。

xscreensaver is now developed mostly on OSX, and uses the OSX screensaver API there and something else on X11.
