I've attempted to write a dialog for Maya using GTK but it consistently
causes segfaults.
The dialog will launch and return successfully but the next button I
press will causes a Maya crash with the message
The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 62194 error_code 8 request_code 42 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.)
And so far I've been unable to geta back trace out of GDB or Totalview.
I've narrowed it down to a test case
string create_dialog {
int argc = 0;
char** argv = 0;
// Initialize the widget set
if (!gtk_init_check (&argc, &argv)) {
return "";
}
// drain the event loop
while (gtk_events_pending ()) {
gtk_main_iteration ();
}
return "";
}
either with or without the event loop draining.
Am I doing something fundamentally wrong? Do I need to do somethign with
XEmbed? Is GTK just not suited to this? Do I need to sacrifice a
different breed of chicken?
I'm using GTK 2.69 for what it's worth.
