Re: how to prevent Gtk::Entry to "Pass on" key event?

[Yann Leydier <yann leydier info>]

The keypress event has a return value that tells if the signal must be 
propagated:
http://developer.gnome.org/gtk/stable/GtkWidget.html#GtkWidget-key-press-event

I hope this means that it can help to tell the entry not to propagate 
the signal to the window. This should be something like adding :

next_file_entry.signal_key_press_event().connect(sigc::mem_fun(this, 
&TWin::no_key_propagate));

bool TWin::no_key_propagate(GdkEventKey*)
{
	return true;
}

If this does not work, then we'll have to conclude that Gtk's doc is 
cryptic on this point…
