[Gtk-sharp-list] subclassing treeview

[Alvaro A. Ramirez]

i'm trying to subclass treeview and override ButtonPressEvent in order
to display a context menu. this compiles fine on gtk# 0.15. on version
0.17 it gives me the following error:

easyTreeview.cs(55) error CS0115: `Gui.EasyTreeview.OnButtonPressEvent'
no suitable methods found to override

any suggestions?


regards, 

Alvaro
