Re: Combo and glist destroy signal problem

[Marco Quezada <mquezada nlxcorp com>]

In the example callback the contents of the combo is cleared without
destroying the combo so that new variables or strings can be added to it.
The line you are looking for is the one I pointed out with the asterix.

Then afterwards, inside the READ_DATA_MATRIX() function I call
gtk_combo_set_popdown_strings on the newly loaded values of the GList to
fill the combo again.

void
on_file_sel_ok_button_clicked          (GtkButton       *button,
                                        gpointer         user_data)
{
   int length;
   int i = 0;
   int j = 0;
   char temp_string[128];

   TAMAL_GLBL->ASCII_FILE_NAME = "";
   TAMAL_GLBL->ASCII_FILE_NAME =

gtk_file_selection_get_filename(GTK_FILE_SELECTION(TAMAL_GLBL->file_selection_dialog));

   length = strlen(TAMAL_GLBL->ASCII_FILE_NAME);

   if(TAMAL_GLBL->ASCII_FILE_NAME[length - 1] != '/')
   {
      TAMAL_GLBL->variable_index_list = NULL;
<---------------------------------******
      while(TAMAL_GLBL->ASCII_FILE_NAME[length] != '/')
      {
         temp_string[i] = TAMAL_GLBL->ASCII_FILE_NAME[length - 1];
         length = length - 1;
         ++i;
      }
      temp_string[i-1] = '\0';
      i = 0;
      length = strlen(temp_string) - 1;
      for(j = length; j >= 0; --j)
      {
         TAMAL_GLBL->SHORT_ASCII_FILE_NAME[j] = temp_string[i];
         ++i;
      }
      TAMAL_GLBL->SHORT_ASCII_FILE_NAME[i] = '\0';
      TAMAL_GLBL->PARAMETERS = 0;

      TAMAL_GLBL->OPENED_FILES = 1;

      UNCOMPRESS_SOURCE_FILE(TAMAL_GLBL->ASCII_FILE_NAME);

      gtk_object_destroy(GTK_OBJECT(TAMAL_GLBL->file_selection_dialog));

      READ_DATA_MATRIX();
   }
   else
   {
      gtk_statusbar_push( GTK_STATUSBAR(TAMAL_GLBL->statusbar),
                            TAMAL_GLBL->status_context_id, "You Sir, are and
IDIOT");

      while (gtk_events_pending())
      {
         gtk_main_iteration();
      }
   }
}
