I want to put in the field gtk.Entry converted characters.

Here it tells how to do it on the GTK:
http://developer.gnome.org/gtk-faq/stable/x842.html

But in gtkD not realized the function g_signal_handlers_block_by_func(),
and I need to stop at the time of recording in the Entry field effect signal addOnInsertText().

If it is not locked, then begins an infinite recursion call this signal.
What are the opportunities to stop the operation signal and then unlock.
