[MonoDevelop] Signals in the property viewer

[alan battersby]

Hi,
I have created a widget that inherits from treeview see code below. It
compiles and appears in the toolbox and I can add it into a design. When
I select my widget in designer I had expected to see the the signals
associated with the base treeview class, but all that is displayed are
the common widget signals. Is there something I should be adding to the
code to make the treeview signals visible in the inspector?

thanks
Alan

                     if (menu != null)
                        menu.Popup();
                     return true;
                }
                // Now if we would ever get this far
                // we run the TreeViews OnButtonPressEvent function
                // to make sure everything else works as normal
                return base.OnButtonPressEvent(evnt);
        }

            menu.Append(itm);
            menu.ShowAll();
        }
