运行 GTK 时出现 X 错误+应用
我已经编写了一个 GTK+ 应用程序，但在运行它时遇到以下 X Window 错误：
The program 'TestApp' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 222 error_code 8 request_code 2 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
此错误的原因可能是什么？我用 C 语言编写了这个应用程序。

What might be the cause of this error? I have written this app in in C.

我会尝试按照它的建议进行操作：使用 --sync cmd 选项运行应用程序并在调试器中启动它，这样您就可以看到哪一行导致了错误。
I would try doing as it suggests: run the application with the --sync cmd option and start it in a debugger, so you can see which line causes the error.
