[Gtk-sharp-list] Custom Cellrenderer

[Toño]

Hi!!
In my app... I need a custom cellrenderer to draw a custom progressbar.
I don't know how to do it in mono-gtk. I have tried to derivate a class
from CellRenderer. But I don't know where or how to draw here. I have
tried overriding Render with no success.
Any help??

Thanks

kind regards
