Multiple inheritance

[jalqadir netscape net]

I am writing a class that must inherit from Gtk::VBox and Gtk::Entry, however, the compiler complains about this saying:

In file included from ../jme/gtkmmwidget/gtkmmwidget.cpp:2:
../jme/gtkmmwidget/gtkmmwidget.hpp:21: error: no unique final overrider for `virtual void Glib::ObjectBase::destroy_notify_()' in `jme::TextEntry'
../jme/gtkmmwidget/gtkmmwidget.hpp:21: error: no unique final overrider for `virtual void Glib::ObjectBase::set_manage()' in `jme::TextEntry'

../jme/gtkmmwidget/gtkmmwidget.hpp:21: error: no unique final overrider for `virtual void Glib::ObjectBase::destroy_notify_()' in `jme::TextEntry'
../jme/gtkmmwidget/gtkmmwidget.hpp:21: error: no unique final overrider for `virtual void Glib::ObjectBase::set_manage()' in `jme::TextEntry'

make.exe: *** [../jme/gtkmmwidget/gtkmmwidget.o] Error 1

Execution terminated

 

-- snip --

class TextEntry : public Gtk::VBox, public Gtk::Entry{...};

-- end of snip --

What am I doing wrogn?
