RE: global cursor setting?

Havoc,

Thanks for pointing out the memory leak, I had written the code this way to
ensure that my problem wasn't due to a variable not being set properly.
Here is the code segement where I set the cursor in file gtkfilesel.c.  

static void
gtk_file_selection_populate (GtkFileSelection *fs,
                             gchar            *rel_path,
                             gint              try_complete)
{
  CompletionState *cmpl_state;
  PossibleCompletion* poss;
  gchar* filename;
  gint row;
  gchar* rem_path = rel_path;
  gchar* sel_text;
  gchar* text[2];
  gint did_recurse = FALSE;
  gint possible_count = 0;
  gint selection_index = -1;
  gint file_list_width;
  gint dir_list_width;
  
  g_return_if_fail (fs != NULL);
  g_return_if_fail (GTK_IS_FILE_SELECTION (fs));
  
  /* Changing cursor to let user know application is busy */
  if ( GTK_WIDGET(fs)->window != NULL )
        gdk_window_set_cursor(GTK_WIDGET(fs)->window,
gdk_cursor_new(GDK_WATCH));

  cmpl_state = (CompletionState*) fs->cmpl_state;
  poss = cmpl_completion_matches (rel_path, &rem_path, cmpl_state);

  ...

  if (!did_recurse)
    {
  /* Changing cursor to let user know application is ready */
  if ( GTK_WIDGET(fs)->window != NULL )
        gdk_window_set_cursor(GTK_WIDGET(fs)->window, 0);
    }
