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.
