\section{\class{wxGenericValidator}}\label{wxgenericvalidator}

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 \helpref{Validator overview}{validatoroverview}.

\func{}{wxGenericValidator}{\param{const wxGenericValidator\&}{ validator}}

Copy constructor.

\func{}{wxGenericValidator}{\param{bool*}{ valPtr}}

Constructor taking a bool pointer. This will be used for wxCheckBox and wxRadioButton.

\func{}{wxGenericValidator}{\param{wxString*}{ valPtr}}

Constructor taking a wxString pointer. This will be used for wxButton, wxComboBox, wxStaticText,
wxTextCtrl.

\func{}{wxGenericValidator}{\param{int*}{ valPtr}}

Constructor taking an integer pointer. This will be used for wxGauge, wxScrollBar, wxRadioBox, wxSpinButton,
wxChoice.

\func{}{wxGenericValidator}{\param{wxArrayInt*}{ valPtr}}

Constructor taking a wxArrayInt pointer. This will be used for wxListBox, wxCheckListBox.

\wxheading{Parameters}

\docparam{validator}{Validator to copy.}

\docparam{valPtr}{A pointer to a variable that contains the value. This variable
should have a lifetime equal to or longer than the validator lifetime (which is usually
determined by the lifetime of the window).}
