不正确派生的Gtk :: Toolbar_Helpers :: ToggleElem类

Question

我有一个不正确派生的Gtk :: Toolbar_Helpers :: ToggleElem类来自 gtkglextmm库。

是否有人熟悉这些GNOME课程？我无法找到最新版本的文档。

#define TOOLTOGGLEBUTTON_H

#include <gtkmm/toolbar.h>


/**
provides Gtk::toolbar togglebutton with extra access methods

@author Karsten Bohlmann
*/
class ToolToggleButton : public Gtk::Toolbar_Helpers::ToggleElem 
{
public:
  ToolToggleButton(const Glib::ustring& text,
   const SigC::Slot0<void> & callback,
   const Glib::ustring& tooltip_text = Glib::ustring(), 
   const Glib::ustring& tooltip_private_text = Glib::ustring());
  ~ToolToggleButton();
  void setActive (bool isActive);  
};

#endif

导致以下错误：
