wxValidator 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.
