I am desperate to get this problem solved but if my question is silly, rather than ignoring me, please let me know so that I can rephrase my question. This is my second post with regards to this problem but despite hundreds of views there has been no reply. I fully understand that respondents are volunteers and appreciate any offer of help.

I would be grateful to hear from any body that could offer even the slightest insight into this issue.

I have recompiled wxWidgets 3.1 against GTK-2 but making a call to: SDL_Window *sdl_window = SDL_CreateWindowFrom((void*) panel->GetHandle()); causes the following message:

: Gdk-ERROR **: The program 'program name' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 138 error_code 3 request_code 20 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.)

RUN FINISHED; Trace/breakpoint trap; core dumped; real time: 700ms; user: 20ms; system: 70ms

When compiled against GTK3 the above error goes away but SDL_CreateRenderer(window, -1, SD_RENDERER_ACCELERATED) never returns. I.E. It seems to hang...

Many thanks
