A few words about all the classes defined in this file are probably in
- order: why do we need extra wxComboControl and wxComboPopup classes?
+ order: why do we need extra wxComboCtrl 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
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
+ So we define a base wxComboCtrl which can use any control as pop down
list and wxComboBox deriving from it which implements the standard wxWidgets
- combobox API. wxComboControl needs to be told somehow which control to use
+ combobox API. wxComboCtrl 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.
