overview = """\
wxValidator is the base class for a family of validator classes that mediate between a class of control, and application data.
A validator has three major roles:
1. to transfer data from a C++ variable or own storage to and from a control;
2. to validate data in a control, and show an appropriate error message;
3. to filter events (such as keystrokes), thereby changing the behaviour of the associated control.
Validators can be plugged into controls dynamically.
