NAME

Glib::Ex::SignalObject -- object for Glib signal connection

SYNOPSIS

 use Glib::Ex::SignalObject;
 $signal = Glib::Ex::SignalObject->new (object => $my_obj,
                                        name   => 'some-signal',
                                        callback => \&my_handler,
                                        userdata => 'some data');

 $signal->disconnect;   # explicit disconnect
 $signal->connect;      # reconnect later
 $signal->set_connected ($bool);  # or control connectedness

 $signal->set_object ($other_obj);   # change origin object
 $signal->set_name ('diff-signal');  # change signal name

 $signal = undef;       # disconnected by forgetting

DESCRIPTION

Glib::Ex::SignalObject is an object-oriented way to manage a signal connection on a Glib object (including Gtk widgets). It features,

• Automatic disconnect by just forgetting the object
• Changable origin and name settings to move the connection to somewhere else, including undef to have no connection for a time.
• A "connect" state to have a connection not made for a time.
• Optional weakening of the userdata to avoid circular references (and disconnect when that target goes away).

FUNCTIONS

    object          originating object (Glib::Object etc), or undef
    name            signal name (string), or undef
    callback        handler function to call
    userdata        data passed to the callback function
