GtkStack and needs-attention property

[Daniel Kasak <d j kasak dk gmail com>]

Hi all.

I can see how to set the 'needs-attention' property while creating and
adding children to a GtkStack. However I don't see how to set the
'needs-attention' property once all widgets are constructed.

If I later use 'gtk_stack_get_child_by_name' I can get the widget that
I added to the stack ( in my case, a GtkBox ), but can't set the
'needs-attention' property on it:

Gtk3::Box does not support property 'needs-attention'.

Is there a way to do this?
