[Qgis-developer] Prevent delete selected features

[Enrico Fiore]

Hi,
I need to avoid features deletion in some layers both from button and from keyboard. 

How can I perform this in pyqgis?

I have disabled the button with these comand:
    iface.actionDeleteSelected().setDisabled(True)

but the features can be deleted with the backspace or Del.

Enrico
