Inheritance diagram for wx.NotifyEvent:
This class is not used by the event handlers by itself, but is a base class for other event classes (such as wx.NotebookEvent).
It (or an object of a derived class) is sent when the controls state is being changed and allows the program to Veto this change if it wants to prevent it from happening.

Constructore. Used internally.
Parameters:
Returns:
Returns True if the change is allowed (Veto hasn’t been called) or False otherwise (if it was).
Returns:
bool
Prevents the change announced by this event from happening.
It is in general a good idea to notify the user about the reasons for vetoing the change because otherwise the applications behaviour (which just refuses to do what the user wants) might be quite surprising.
