Hi

Well, i only have gtk2 and I got

GLib-GObject-WARNING **: invalid (NULL) pointer instance GLib-GObject-CRITICAL **: g_signal_connect_data: assertion `G_TYPE_CHE +CK_INSTANCE (instance)' failed ... Can't locate object method "timeout_add" via package "Gtk2" ... Usage: Gtk2::main(class)

Checking around my harddisk i see

site\lib\Gtk2\api.pod 260:=item gtk_timeout_add => Glib::Timeout->add 262:=item gtk_timeout_remove => Glib::Source->remove

Gtk2::api

So this is what finally works, you should try swapping Gtk2/Gtk3 and see if it works for you :)

#!/usr/bin/perl -- use strict; use warnings; # use Gtk2; use Gtk2 -init; my $window = Gtk2::Window->new ('toplevel'); my $button = Gtk2::Button->new ('Quit'); $button->signal_connect (clicked => sub { Gtk2::main_quit }); $window->add ($button); $window->show_all; my $data = 'data'; # my $id = Gtk2->timeout_add(1000, \&handler, $data); my $id = Glib::Timeout->add(1000, \&handler, $data); Gtk2->main; sub handler { my ($data) = @_; print "timed out ... @_\n"; # return 1 if you want the handler to be called again later # return 0 to stop the handler from being called again return 1; } __END__
