Debugging X errors in Gtk

[Cabhan]

Howdy all. I'm writing a program with Gtk, and I'm getting an error that I don't understand.

My program essentially displays images. That worked. So my image-viewing code works (I am using the same images, and I have not touched that code).

I have recently attempted to add a text bar across the top that displays the path of the current image. In doing so, I added a vbox and an entry. This seems to have ruined everything.

When I run the program now, just after gtk_main() is called, my program quits and gives the following X error:

The program 'a.out' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 319 error_code 9 request_code 72 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.)

When I run my program in gdb, I get this error:

The program 'a.out' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 332 error_code 11 request_code 53 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.)

Aside from the fact that these are different errors, they offer no help whatsoever. Also note that in the gdb one, I set _Xdebug = 1, which according to a guide, should give me synchronous reporting of X errors.

Does anyone have any experience in dealing with these errors before? I can certainly provide code if that would help.

The dreaded X error code...I've seen my share of those. If you feel like it, you can send your code to me at hoelz@wisc.edu and I'll get to it probably some time today. The problem is probably that you're drawing on a Window or Pixmap that doesn't exist.

Thanks a bunch for the offer! It is happily bundled and on its way to you.
