I am surprised that g++ doesn't give you a warning while compiling that piece of code. In "MainWindow::onTimeout30s()" you have forgotten to return a value. Put "return true;" If you want MainWindow::onTimeout30s() to be called again or "return false" to disconnect the signal handler. > From: mik gmx org > To: gtkmm-list gnome org > Subject: Glib::signal_timeout().connect_seconds > Date: Sat, 17 Oct 2009 12:52:11 +0200 > > Hello everybody! > > I have a strange problem when using signal_timeout().
