EditWindow.C: In constructor `EditWindow::EditWindow(GtkEventBox*, const
   Glib::RefPtr<Gnome::Glade::Xml>&)':
EditWindow.C:4: error: type `class Gtk::EventBox' is not a direct or 
virtual
   base of `EditWindow'




here's there actual constructors:

BaseChip.C:
----------
BaseChip::BaseChip(const Glib::RefPtr<Gnome::Glade::Xml> & g) :
    _type(EMPTY_EMPTY),
    _xml(g),
    drawHeight(100),
    drawWidth(100)
{
    // connect the drawingarea signals
    _drawarea.signal_realize().connect(
        sigc::mem_fun(*this, &BaseChip::drawarea_realize));
    _drawarea.signal_expose_event().connect(
        sigc::mem_fun(*this, &BaseChip::drawarea_expose_event));

    // setup eventbox
    set_size_request(drawWidth, drawHeight);
    add(_drawarea);
    set_events(Gdk::BUTTON_PRESS_MASK);
    signal_button_press_event().connect(
        sigc::mem_fun(*this, &BaseChip::button_press));

    // initialize the chip as empty
    init_empty();

    // show widgets
    _drawarea.show();
}



EditWindow.C:
------------EditWindow::EditWindow(GtkEventBox * e, const 
Glib::RefPtr<Gnome::Glade::Xml> & g) :
    Gtk::EventBox(e),
    BaseChip(g)
{
    init_empty();
}
