GTKmm on Windows (porting) - sigc::mem_fun returning errors from VC++ Express 2010 about deducing template arguments

Question

I am trying to port my GTKmm application developed in Linux into Windows. I have a treeview with multiple selections and I need to get those selections into an std::vector. The code I use (and that works fine in Linux) is this:

        std::vector<Gtk::TreeModel::iterator> rows;
    mp_FileDetailsTree->treeSelection()->selected_foreach_iter(
        sigc::mem_fun(rows, &std::vector<Gtk::TreeModel::iterator>::push_back)
        );

On Windows, however, (Visual C++ Express 2010) I get a lot of this error (repeated quite a bit):

error C2784: 'sigc::bound_const_volatile_mem_functor7<T_return,T_obj,T_arg1,T_arg2,T_arg3,T_arg4,T_arg5,T_arg6,T_arg7> sigc::mem_fun(T_obj &,T_return (__thiscall T_obj2::* )(T_arg1,T_arg2,T_arg3,T_arg4,T_arg5,T_arg6,T_arg7) volatile const)' : could not deduce template argument for 'overloaded function type' from 'overloaded function type'
      c:\devel\gtkmm\include\sigc++-2.0\sigc++\functors\mem_fun.h(6196) : see declaration of 'sigc::mem_fun'

Right at the sigc::mem_fun line.

Any idea how I can fix this? Googling has turned up nothing useful :(. I'm using GTKmm 2.22 (full Windows installer).

Answer 1

Directly using std::vector::push_back as a signal handler is rather ambitious. I'm not surprised that the compiler is confused.

I would just use a regular signal handler method and call vector::push_back() inside that method.
