[Gtk-sharp-list] Position of text and icons in a button

[Raúl Moratalla]

Hi again, I have the following question:
is there any way to set the position of the text and icon in a button? I 
want the text at the bottom of the button and the icon above it.
I can edit my button with glade and modify it using static positions 
inside it but, Is there an elegant way to do it?

Best regards,

Raúl
