Hello, I am not sure this is the correct way to get help on gtkmm GUI program. Please let me know.
I am having a compiling error when compiling the notebook example on the following web-page. http://library.gnome.org/devel/gtkmm-tutorial/unstable/sec-multi-item-containers.html.en#sec-notebook This is offendinf code: m_Notebook.signal_switch_page().connect(sigc::mem_fun(*this, &ExampleWindow::on_notebook_switch_page) ); Here is the compilation errors: ********************************************************************************************** [c...@localhost notebook]$ make g++ -o obj/Linux/examplewindow.o -c -Iinc `pkg-config gtkmm-2.4 --cflags` src/examplewindow.cpp In file included from /usr/include/sigc++-2.0/sigc++/functors/slot.h:7, from /usr/include/sigc++-2.0/sigc++/signal_base.h:28, from /usr/include/sigc++-2.0/sigc++/signal.h:8, from /usr/include/sigc++-2.0/sigc++/sigc++.h:23, from /usr/include/glibmm-2.4/glibmm/signalproxy.h:13, from /usr/include/glibmm-2.4/glibmm/objectbase.h:23, from /usr/include/glibmm-2.4/glibmm/wrap.h:26, from /usr/include/glibmm-2.4/glibmm/containerhandle_shared.h:25, from /usr/include/glibmm-2.4/glibmm/arrayhandle.h:23, from /usr/include/glibmm-2.4/glibmm.h:27, from /usr/include/gtkmm-2.4/gtkmm.h:29, from inc/examplewindow.h:4, from src/examplewindow.cpp:2: /usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h: In member function ‘typename sigc::adaptor_functor<T_functor>::deduce_result_type<T_arg1, T_arg2, void, void, void, void, void>::type sigc::adaptor_functor<T_functor>::operator()(T_arg1, T_arg2) const [with T_arg1 = GtkNotebookPage* const&, T_arg2 = const unsigned int&, T_functor = sigc::bound_mem_functor2<void, ExampleWindow, Gtk::Widget*, unsigned int>]’: /usr/include/sigc++-2.0/sigc++/functors/slot.h:173: instantiated from ‘static T_return sigc::internal::slot_call2<T_functor, T_return, T_arg1, T_arg2>::call_it(sigc::internal::slot_rep*, typename sigc::type_trait<T_arg3>::take, typename sigc::type_trait<T_arg4>::take) [with T_functor = sigc::bound_mem_functor2<void, ExampleWindow, Gtk::Widget*, unsigned int>, T_return = void, T_arg1 = GtkNotebookPage*, T_arg2 = unsigned int]’ /usr/include/sigc++-2.0/sigc++/functors/slot.h:180: instantiated from ‘static void* (* sigc::internal::slot_call2<T_functor, T_return, T_arg1, T_arg2>::address())(void*) [with T_functor = sigc::bound_mem_functor2<void, ExampleWindow, Gtk::Widget*, unsigned int>, T_return = void, T_arg1 = GtkNotebookPage*, T_arg2 = unsigned int]’ /usr/include/sigc++-2.0/sigc++/functors/slot.h:607: instantiated from ‘sigc::slot2<T_return, T_arg1, T_arg2>::slot2(const T_functor&) [with T_functor = sigc::bound_mem_functor2<void, ExampleWindow, Gtk::Widget*, unsigned int>, T_return = void, T_arg1 = GtkNotebookPage*, T_arg2 = unsigned int]’ /usr/include/sigc++-2.0/sigc++/functors/slot.h:1184: instantiated from ‘sigc::slot<T_return, T_arg1, T_arg2, sigc::nil, sigc::nil, sigc::nil, sigc::nil, sigc::nil>::slot(const T_functor&) [with T_functor = sigc::bound_mem_functor2<void, ExampleWindow, Gtk::Widget*, unsigned int>, T_return = void, T_arg1 = GtkNotebookPage*, T_arg2 = unsigned int]’ src/examplewindow.cpp:30: instantiated from here /usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h:103: error: no match for call to ‘(sigc::bound_mem_functor2<void, ExampleWindow, Gtk::Widget*, unsigned int>) (GtkNotebookPage* const&, const unsigned int&)’ /usr/include/sigc++-2.0/sigc++/functors/mem_fun.h:1916: note: candidates are: T_return sigc::bound_mem_functor2<T_return, T_obj, T_arg1, T_arg2>::operator()(typename sigc::type_trait<T_arg3>::take, typename sigc::type_trait<T_arg4>::take) const [with T_return = void, T_obj = ExampleWindow, T_arg1 = Gtk::Widget*, T_arg2 = unsigned int] /usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h:103: error: return-statement with a value, in function returning 'void' make: *** [obj/Linux/examplewindow.o] Error 1 [c...@localhost notebook]$ --------------------------------------------------------------------------------------------------------------------------------------------- Thanks, Chun
