- 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.
