    @class wxCheckListBox

    A wxCheckListBox is like a wxListBox, but allows items to be checked or
    unchecked.

    When using this class under Windows wxWidgets must be compiled with
    wxUSE_OWNER_DRAWN set to 1.

    @beginEventEmissionTable{wxCommandEvent}
    @event{EVT_CHECKLISTBOX(id, func)}
        Process a @c wxEVT_COMMAND_CHECKLISTBOX_TOGGLED event, when an item in
        the check list box is checked or unchecked. wxCommandEvent::GetInt()
        will contain the index of the item that was checked or unchecked.
        wxCommandEvent::IsChecked() is not valid! Use wxCheckListBox::IsChecked()
        instead.
