RE: Help: how to disconnect a signal?

["Tom Liu" <tom liu flextrade com>]

I didn't record the id of the signal and don't know how many functions
conneted. I just want to disconnect all the connected functions.

The thing I need this is I am porting the Motif to GTK.
In the old program, I have a pice of code like:
        Widget widg;
        XtRemoveAllCallbacks(widg, XmNmodifyVerifyCallback);
        XtRemoveAllCallbacks(widg, XmNactivateCallback);

Thanks.

gulong id;

id = g_signal_connect(button, "clicked", G_CALLBACK(onButtonClicked),
NULL);

g_signal_handler_disconnect(button, id);


or:

g_signal_connect(button, "clicked", G_CALLBACK(onButtonClicked), NULL);

g_signal_handlers_disconnect_by_func(button, onButtonClicked, NULL);


See http://developer.gnome.org/doc/API/2.0/gobject/gobject-Signals.html
