Don't emit "cursor-changed" during destroy cycle (421 bytes, text/plain)

Description John Lindgren 2012-07-03 00:23:55 UTC 
Created attachment 217892 [details]
Don't emit "cursor-changed" during destroy cycle

Bug is present in GTK+ 3.4.3.

Brief call stack:
  gtk_tree_view_destroy() calls
  gtk_tree_view_set_model(), which calls
  gtk_tree_view_real_set_cursor(),
  which emits the "cursor-changed" signal on the GtkTreeView.

This leads to unexpected situations for handlers installed on the "cursor-changed" signal, such as gtk_tree_view_get_selection() returning NULL.

The attached patch checks gtk_widget_in_destruction() before emitting the "cursor-changed" signal.
