Python 的 Gnome 屏幕保护程序？
我用 Python 创建了一个小屏幕保护程序类型的程序，我想让它在 gnome-screensaver 下正常工作。文档都是针对 C 语言编写的，似乎没有针对 Python 的库。有什么办法可以让它发挥作用吗？
I've created a little screensaver-type program with Python, and I'd like to get it working properly under gnome-screensaver. The documentation is all written for C, and there don't appear to be libraries for Python. Is there any way to get this working?

gnome-screensaver 不与屏幕保护程序集成，就像与一个小配置文件集成一样，该配置文件设置名称、一些其他属性以及启动屏幕保护程序所需执行的命令。这在 gnome-screensaver FAQ 中有记录。
启动的程序需要从环境中获取窗口 ID (
XSCREENSAVER_WINDOW)，并开始在该窗口上显示。这是棘手的部分，因为如何做到这一点并不总是显而易见的。大多数工具包应该有方法通过提供 ID 来获取现有窗口的句柄，因此请在 GUI 工具包文档中搜索类似的内容。gnome-screensaver doesn't integrate with the screensavers any more than with a small config file that sets the name, some other properties, and a command to execute to start the screensaver. This is documented in the gnome-screensaver FAQ.
The program that gets started needs to get the Window ID from the environment (
XSCREENSAVER_WINDOW), and start displaying on that window. This is the tricky part, as it's not always obvious how to do that. Most toolkits should have methods to get a handle on an already existing window by giving the ID, so search your GUI-toolkit documentation for something like that.
