/**
    @class wxGenericValidator
    @wxheader{valgen.h}

    wxGenericValidator performs data transfer (but not validation or filtering) for
    the following
    basic controls: wxButton, wxCheckBox, wxListBox, wxStaticText, wxRadioButton,
    wxRadioBox,
    wxChoice, wxComboBox, wxGauge, wxSlider, wxScrollBar, wxSpinButton, wxTextCtrl,
    wxCheckListBox.

    It checks the type of the window and uses an appropriate type for that window.
    For example,
    wxButton and wxTextCtrl transfer data to and from a wxString variable;
    wxListBox uses a
    wxArrayInt; wxCheckBox uses a bool.

    For more information, please see @ref overview_validatoroverview "Validator
    overview".
