In your NodeView / TreeView (this example is from a NodeView)
##########
[GLib.ConnectBefore]
public void OnButonPressEvent(object _sender,
ButtonPressEventArgs _args)
ITreeNode node;
Enterprise enterprise;
if (PopupEnabled)
{
/* Get the selected list node from the nodeview
and bail out if result is not a EnterpriseListNode */
node = (_sender as NodeView).NodeSelection.SelectedNode;
if (node is EnterpriseListNode)
enterprise = ((EnterpriseListNode)node).Enterprise;
else return;
/* Is the click a right-button */
if (_args.Event.Button == 3)
{
PopupMenuBuilder menu;
menu.Append("Edit", enterprise,
newEventHandler (EnterpriseEdit),
(OnEnterpriseEdit != null));
....
menu.Run();
}
##########
I cheat a little bit by having my own PopupMenuBuilder class; mostly
because the delegate needs the item represented by the node/row that was
selected in the view.
