[Qt] ComboBox OnChange and OnSelect

[Juha Manninen]

Hi,

I don't know which is the right behavior but GTK2 and QT bindings work 
differently.
With QT bindings, ComboBox OnChange and OnSelect events are called also when 
adding items in program like:
  ComboBox.Items.Add('text');
With GTK2 bindings they are not called.

I needed to react only when user selects an item in combobox. The GTK version 
worked straight away but I had to make an "UpdatingList" flag to make the QT 
version work.

Now, calling OnChange when items are added is actually logical (because the 
list is changing) but OnSelect should be called only on user's selection 
(IMO).

I don't know how Delphi does it.
