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:
Validators can be plugged into controls dynamically.
To specify a default, `null' validator, use the symbol wxDefaultValidator.
For more information, please see Validator overview.
wxPython での注意点: If you wish to create a validator class in wxPython you should derive the class from wxPyValidator in order to get Python-aware capabilities for the various virtual methods.

virtual wxObject* Clone(void) const
All validator classes must implement the Clone function, which returns an identical copy of itself. This is because validators are passed to control constructors as references which must be copied. Unlike objects such as pens and brushes, it does not make sense to have a reference counting scheme to do this cloning, because all validators should have separate data.
This base function returns NULL.
wxWindow* GetWindow(void) const
Returns the window associated with the validator.
This functions switches on or turns off the error sound produced by the validators if an invalid key is pressed.
Associates a window with the validator.
This overridable function is called when the value in the window must be transferred to the validator. Return false if there is a problem.
This overridable function is called when the value associated with the validator must be transferred to the window. Return false if there is a problem.
This overridable function is called when the value in the associated window must be validated. Return false if the value in the window is not valid; you may pop up an error dialog.ymasuda 平成17年11月19日
