FileSelection Error

["Audrey Vernon" <audrey vernon colorado edu>]

 

I have the following code to get a filename with a file selection tool, but it gives my the X window error shown below.  Any ideas what might cause this and how I can fix it?

 

 

void WorkspaceManip::saveRawData(GtkWidget *link, WorkspaceManipData *myData)
{
  // Create the file selector
  myData->fileSelector = gtk_file_selection_new ("Save Raw Data");

 

  g_signal_connect(GTK_OBJECT(GTK_FILE_SELECTION
                              (myData->fileSelector)->ok_button),
                   "clicked", G_CALLBACK(rawDataFilename), myData);

 

  g_signal_connect_swapped (GTK_OBJECT
                            (GTK_FILE_SELECTION
                             (myData->fileSelector)->cancel_button),
                            "clicked",
                            G_CALLBACK (gtk_widget_destroy),
                            (gpointer) myData->fileSelector);

 

  // Display that dialog
  gtk_widget_show (myData->fileSelector);
}

 

void WorkspaceManip::rawDataFilename(GtkWidget *w, WorkspaceManipData *myData)
{
  gchar *selected_filename =(gchar *) gtk_file_selection_get_filename
    (GTK_FILE_SELECTION(myData->fileSelector));
  gtk_widget_destroy(myData->fileSelector);
}

 

 

 

 

The program '<unknown>' 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 13370 error_code 9 request_code 55 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.)
