Hi List,
my little program with a treeview throws an exception on that point where=
I try to append some data to a Treestore.
...
store =3D new Gtk.TreeStore((int)TypeFundamentals.TypeString);
TreeIter iter =3D new TreeIter ();
store.Append(out iter); //<- Here comes the exception.
Unhandled Exception: System.DllNotFoundException: Unable to load DLL (gtk=
-x11-2.0).
at Gtk.TreeStore.gtk_tree_store_append(IntPtr raw, TreeIter& iter, Int=
Ptr
par
ent)
at Gtk.TreeStore.Append(TreeIter& iter)
at GladeTest.on_open2_activate(Object obj, EventArgs e)
at GtkSharp.voidObjectSignal.voidObjectCallback(IntPtr arg0, Int32 key=
)
at Gtk.Application.gtk_main()
at Gtk.Application.Run()
at GladeTest..ctor(String[] args)
at GladeTest.Main(String[] args)
I don't have that gtk-x11-2.0.dll on my Win 2003 Srv with mono-023 and Gt=
k-2.0.
Regards,
Andreas
