custom signals

[Dimitri Giardina <dimitri giardina gmail com>]

Hi list,

i'm searching for some days on google about attaching custom signals to custom widgets on gjs.
i see some examples for seed-js but they seem not to be applicable on gjs.

i found the overriding of gobject.js but i don't know if i can use that:
https://mail.gnome.org/archives/commits-list/2012-January/msg11238.html

something like:
        gi.signal_new(this.prototype,'close-clicked',GObject.SignalFlags.RUN_FIRST,GObject.AccumulatorType.NONE,GObject.TYPE_NONE,[]);

where gi is const gi=imports.gi; 
but it don't work.

if i use 
this.connect('close-clicked',this.close_clicked);

interpreter give me a message that close-ticket is not one of signals. 

anyone can help me?

thanks
Dimitri.
