| 107 | wxValidator is the base class for a family of validator classes that mediate between a class of control, and application data. | |
| 108 | ||
| 109 | A validator has three major roles: | |
| 110 | ||
| 111 | 1. to transfer data from a C++ variable or own storage to and from a control; | |
| 112 | ||
| 113 | 2. to validate data in a control, and show an appropriate error message; | |
| 114 | ||
| 115 | 3. to filter events (such as keystrokes), thereby changing the behaviour of the associated control. | |
| 116 | ||
| 117 | Validators can be plugged into controls dynamically. | |
