Auto-connection signals with GtkBuilder but on GTKmm

In C, I can autoconnect signals with this code:

gtk_builder_connect_signals (builder, NULL)

How to do this in C++ with GTKmm?

Solution

  • You cannot use Glade to connect your signals when using gtkmm, you need to do that manually.

        Glib::RefPtr builder = Gtk::Builder::create_from_file("glade_file.ui");

    Gtk::Window *window1 = 0;
    builder->get_widget("window1", window1);

    Gtk::Button *button1 = 0;
    builder->get_widget("button1", button1);
    // get other widgets
    ...

    button1->signal_clicked().connect(sigc::mem_fun(*this, &button1_clicked));
