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