Re: [Vala] How to connect to signal if there's a property with the same name?

[Luc Chante <luc chante gmail com>]

Hi,

According to this
https://git.gnome.org/browse/vala/tree/vapi/gio-2.0.vapi#n516 it seems that
the signal isn't bound in vala. Maybe vala doesn't accept yet that a
property and a method (signal) have the same name.

As Robert Schroll says, connect to the notify signal of the property.
"...
        connection.notify["closed"].connect(on_dbus_connection_closed)
..."
go to : https://wiki.gnome.org/Projects/Vala/Tutorial#line-1112
