[Gtk-sharp-list] Context Menu On A TreeView Row

[Adam Tauno Williams]

I am trying to build a popup menu attached to a click or popup event
(Shift F10) on items in a treeview.  Does anyone have a Gtk#/C# example
for doing this?  I've tried translating from an example in C but
apparently I've missed something.

1.) The ButtonPressEvent doesn't get fired when a row is clicked on, 
although the row does become 'highlighted' normally.
2.) The PopUp event does fire, but no menu appears.

....
teamTreeView = new TreeView();
....
teamTreeView.PopupMenu += on_tree_popup_menu;
teamTreeView.ButtonPressEvent += on_tree_button_press;
....
}

public void on_tree_popup_menu(object o, PopupMenuArgs args)
{
Console.WriteLine("ComlaborareTeams:on_tree_popup_menu");
DoPopUp();
}
		
public void on_tree_button_press(object o, ButtonPressEventArgs args)
{
Console.WriteLine("ComlaborareTeams:on_tree_button_press");
if (args.Event.Button == 3)
 {
  DoPopUp();
 }
}

protected void DoPopUp()
{
 Menu popup = new Menu();
 popup.Add(new MenuItem("Edit"));
 popup.Add(new MenuItem("Remove"));
 popup.Popup(null, null, null, IntPtr.Zero, 3,
Gtk.Global.CurrentEventTime);
}
