GtkSharp/gtk/ListStore.custom
Mike Kestner b108f0142e 2007-04-17 Mike Kestner <mkestner@novell.com>
* gtk/Gtk.metadata : hide TreeModel.RowsReordered signal so we can do
	a correct implementation while maintaining compat with the existing 
	broken "NewOrder" parameter.
	* gtk/ListStore.custom : manual RowsReordered signal implementation.
	* gtk/RowsReorderedHandler.cs : manual implementation for preserve compat
	in the Args class. Adds NewChildOrder to replace the broken ChildOrder.
	* gtk/TreeModel.custom : manual RowsReordered signal declaration.
	* gtk/TreeModelFilter.custom : manual RowsReordered signal implementation.
	* gtk/TreeModelSort.custom : manual RowsReordered signal implementation.
	* gtk/TreeStore.custom : manual RowsReordered signal implementation.
	[Fixes #78512]
