sorry; I'm confusing my larger design problem with smaller technical
problems and it makes it hard to see what the specific complaint is.
here is a small file; t.vala, compile it with:
valac --pkg gtk+-2.0 t.vala
The problem is that Subclass cannot access protected member "widgets" of
the Superclass.
[EMAIL PROTECTED]:~/projects/vala/phoneui/src$ valac --pkg gtk+-2.0 t.vala
t.vala:13.5-13.16: error: Access to private member `window_widgets.blah'
denied
widgets.blah=null;
^^^^^^^^^^^^
Compilation failed: 1 error(s), 0 warning(s)
The widgets member is declared in the .h file (therefore public-ish),
but vala still call's it private.
using Gtk;
protected struct window_widgets {
Gtk.Object blah;
}
public class Superclass : Gtk.Object {
protected window_widgets widgets;
}
public class Subclass : Superclass {
construct {
widgets.blah=null;
}
}
