## Detailed Description

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 wxValidator Overview.
