Hi,
Your description is correct. Forms are a component that is not per se
strictly part of Base, it is shared with also at least Writer and
Calc. They are just used much more intensively by Base than by other
parts of LibreOffice :)
In first approximation, the work you describe would happen entirely
within the Forms component, files
forms/source/component/ListBox.cxx
forms/source/component/ListBox.hxx
forms/source/component/BaseListBox.hxx
plus the service/interface definition for a ListBox in
offapi/com/sun/star/form/component/ListBox.idl
offapi/com/sun/star/form/control/ListBox.idl
plus the low-level implementation
vcl/source/control/listbox.cxx
vcl/source/control/imp_listbox.cxx
vcl/inc/listbox.hxx
Best Regards,
Lionel
