Gtk3 introspection updates and Unusable Unity..

So on with the harder stuff.. - Gtk3 and introspection.

TreeIter and TextIter 

var iter = new Gtk.TreeIter();
model.get_iter_from_string(iter, path);
// iter would now contain the tree iter for that path..

var iret = {};
model.get_iter_from_string(iret, path);
// iret.iter now contains the tree iter.

TreeSelection 

var iter = new Gtk.TreeIter();
selection.get_selected(model, iter);

var sret = {};
selection.get_selected(sret);
// sret now contains { model: **THE MODEL**, iter: **THE ITER** }

TreeModel get_value

var value = new GObject.Value('');
model.get_value(iter, 2, value);
print(value.value);

var str = model.get_value(iter, 2).value.get_string();
print(str);

Drag pixmap becomes surfaces

var pix = widget.create_row_drag_icon ( path);
Gtk.drag_set_icon_pixmap (ctx, pix.get_colormap(),   pix,  null, ..... )

var pix = widget.create_row_drag_icon ( path);
Gtk.drag_set_icon_surface(ctx, pix);

Drag drop data passing..

Drag drop API

GtkWidget.prototype.drag_source_set -> Gtk.drag_source_set
Gtk.drag_source_set_target_list -> GtkWidget.prototype.drag_source_set_target_list
Gtk.drag_dest_set -> GtkWidget.prototype.drag_dest_set

Internal Seed changes

-                  out_args[n_out_args].v_pointer = g_malloc0 (size);
+                  out_args[n_out_args].v_pointer = g_malloc0 (size+ 1);

-  object = g_slice_alloc0 (size);
+  object = g_slice_alloc0 (size +1);
