While trying to use GTK 3 frame clock in a Python 3 script, I discovered that I don't understand how to invoke the equivalent of gdk_frame_clock_get_refresh_info(). I have first tried the obvious, to call the get_refresh_info() method on the object returned by get_frame_clock():
在尝试在Python 3脚本中使用GTK 3帧时钟时，我发现我不知道如何调用等效的gdk_frame_clock_clock_get_refresh_info()。我首先尝试了一个显而易见的方法，在get_frame_clock()返回的对象上调用get_refresh_info()方法:
from gi.repository import Gtk as gtk, GLib as glib
w = gtk.Window()
w.show()
glib.idle_add(lambda: print(w.get_frame_clock().get_refresh_info()))
gtk.main()
That fails with:
失败:
TypeError: Gdk.FrameClock.get_refresh_info() takes exactly 4 arguments (1 given)
The C function indeed takes four arguments, but the last two are pointers to gint64. In the Python version the function raises type errors when called with anything except three numbers. When invoked with three numbers, the whole process crashes with a segmentation fault.
C函数确实有四个参数，但最后两个是指向gint64的指针。在Python版本中，除了三个数字外，当调用任何东西时，该函数都会引发类型错误。当使用三个数字调用时，整个进程会因分割错误而崩溃。
Is this a bug in GDK's introspection specs for gdk_frame_clock_get_refresh_info? Is there a workaround, or a different way to obtain the refresh interval?
这是GDK的gdk_frame_clock_get_refresh_info内省规范中的一个错误吗?是否有一种解决方案，或者另一种获取刷新间隔的方法?

This is a bug in the gobject-introspection binding specs. A proper bug report has been filed and is being worked on here.
这是gobject-introspection绑定规范中的一个错误。一个合适的错误报告已经被归档并正在这里工作。
