Hi, I got a sub-class of a TreeStore (see below) and I want to cancel a
DND operation if it's not apropriate. But my RowDraggable method is
never called.. I'am missing something ?

public class MyTreeStore : TreeStore, TreeDragSource {
	public MyTreeStore(params System.Type[] p) : base(p) {
	bool TreeDragSource.RowDraggable(TreePath path){
		return false;

I use it in a sub-class of a TreeView that goes like that :

public class MyTreeView : TreeView {

	public MyTreeView(){

		this.Reorderable = true;

		this.AppendColumn ("Col1", new CellRendererText(), "text", 0);
		this.AppendColumn ("Col2", new CellRendererText(), "text", 1);
		this.Model = new MyTreeStore(


I known that there is some subtilities to override Interface methods in
sub-classes in C# but, as far as I know, my code take care of it..

Any tought ?
