lgi / gtk : how to create a button from stock ?

[Laurent FAILLIE <l_faillie@...>]

Hello,

I'm wondering if it's possible to create a button using "Lua syntaxe".
I mean, for label, I can use the following code :

    child = Gtk.Button{
        label = "_hello",
        use_underline = true
    }

but is it a way to do do te same to create an stock based button ?

I know for Gtk.ToolButton, it's working by setting stock_id, but I didn't find equivalent for Gtk.Button ...

Thanks

Laurent
