Hello everybody, I am familiar with GTK+ and new to libsigc++. I just want to ask you guys if there is a way to use libsigc++ to connect a GTK+ function with a callback function which is a member of a class. Consider this code:
class TopWin { public: //selection_func is a non-static member function. gboolean selection_func(GtkTreeSelection *selection, GtkTreeModel *model, GtkTreePath *path, gboolean path_currently_selected, gpointer user_data); private: //private members here... }; int main(int argc, char *argv[]) { gtk_init(&argc, &argv); //...some codes here //error: can't connect to TopWin::selection_func gtk_tree_selection_set_select_function(l_select, TopWin::selection_func, NULL, NULL); return 0; } Is there anyway to use libsigc++ to connect gtk_tree_selection_set_select_function() to TopWin::selection_func without declaring TopWin::selection_func as static? I thought about using Gtkmm instead of Gtk+ a long time ago but the only Gtkmm tutorial available is in the Gtkmm main website and it is so confusing. I ended up continuing to code in C++ and GTK+. I have also read the libsigc++ tutorial but still unable to solve this problem. I don't want to declare TopWin::selection_func as static because if I do I will have to declare every member of the class static, which is quite painful...! Thank you for reading my message! Have a good weekend! Best regards, Phong Cao,
