REMARKS:
Defines a Custom ComboBox. This combobox is a portable implementation of
the msw combobox control. It is made of the wxWindows textctrl primitive and
the listbox primitive. This object does not create or display the controls,
it provides the relationship and underlying behavior layer for the primitives
allready created via wxDesigner.
