-wx.Validator is the base class for a family of validator classes that mediate
-between a class of control, and application data.
-
-<p>A validator has three major roles:
-
-<p><ol>
-<li>to transfer data from a C++ variable or own storage to and from a control;
-<li>to validate data in a control, and show an appropriate error message;
-<li>to filter events (such as keystrokes), thereby changing the behaviour of the associated control.
-</ol>
-<p>Validators can be plugged into controls dynamically.
