    @class wxGenericValidator

    wxGenericValidator performs data transfer (but not validation or filtering)
    for many type of controls.

    wxGenericValidator supports:
    - wxButton, wxRadioButton, wxToggleButton, wxBitmapToggleButton, wxSpinButton
    - wxCheckBox, wxRadioBox, wxComboBox, wxListBox, wxCheckListBox
    - wxGauge, wxSlider, wxScrollBar, wxChoice, wxStaticText
    - wxSpinCtrl, wxTextCtrl

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

    For more information, please see @ref overview_validator.
