Question

有我是Gtk编程的新手，我在Windows上用VS2010编写了一个演示程序并在Windows 7 x64上顺利运行但是在尝试在linux上运行它时遇到了一个问题，我不能简单地给出一个desc，所以我在这里粘贴错误：

lucid@lucid-desktop:~/Desktop/Debug$ mono NetLockAlert.EmbeddedUI.exe
mono: ../../src/xcb_io.c:249: process_responses: Assertion `(((long) (dpy-          >last_request_read) - (long) (dpy->request)) <= 0)' failed.
Stacktrace:

  at (wrapper managed-to-native) Gtk.Application.gtk_main () <0xffffffff>

很难从这个错误中辨别出来：它是否一致？是每次启动时还是以后都会发生？

最可能的原因是您从多个线程调用GUI：这是不允许的。如果您不在主循环线程中，则应使用类似Gtk.Application.Invoke（）的内容，此页面中提供了示例：http://www.mono-project.com/Responsive_Applications。
