-/*
-   A few words about all the classes defined in this file are probably in
-   order: why do we need extra wxComboControl and wxComboPopup classes?
-
-   This is because a traditional combobox is a combination of a text control
-   (with a button allowing to open the pop down list) with a listbox and
-   wxComboBox class is exactly such control, however we want to also have other
-   combinations - in fact, we want to allow anything at all to be used as pop
-   down list, not just a wxListBox.
-
-   So we define a base wxComboControl which can use any control as pop down
-   list and wxComboBox deriving from it which implements the standard wxWindows
-   combobox API. wxComboControl needs to be told somehow which control to use
-   and this is done by SetPopupControl(). However, we need something more than
-   just a wxControl in this method as, for example, we need to call
-   SetSelection("initial text value") and wxControl doesn't have such method.
-   So we also need a wxComboPopup which is just a very simple interface which
-   must be implemented by a control to be usable as a popup.
-
-   We couldn't derive wxComboPopup from wxControl as this would make it
-   impossible to have a class deriving from both wxListBx and from it, so
-   instead it is just a mix-in.
