中间类型
Some API related to gtkmm uses intermediate data containers, such as Glib::StringArrayHandle, instead of a specific Standard C++ container such as std::vector or std::list, though gtkmm itself now uses just std::vector since gtkmm 3.0.
You should not declare these types yourself. You should instead use whatever Standard C++ container you prefer. glibmm will do the conversion for you. Here are some of these intermediate types:
- Glib::StringArrayHandle 或 Glib::ArrayHandle<Glib::ustring>：使用 std::vector<Glib::ustring>、std::list<Glib::ustring>、const char*[] 等。
- Glib::ListHandle<Gtk::Widget*>：使用 std::vector<Gtk::Widget*>、std::list<Gtk::Widget*> 等。
- Glib::SListHandle<Gtk::Widget*>：使用 std::vector<Gtk::Widget*>、std::list<Gtk::Widget*> 等。
