Inheritance diagram for wx.Validator:
wx.Validator 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 wx.DefaultValidator.
Note
wx.Python note: If you wish to create a validator class in wxPython you should derive the class from wx.PyValidator in order to get Python-aware capabilities for the various virtual methods.
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.
