.SH NAME
wxNotifyEvent \- 
  A notification event, which can be vetoed
 
.SH DESCRIPTION

  


   This class is not used by the event handlers by itself, but is a base class
   for other event classes (such as
   wxNotebookEvent
   ).
  
  


   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.

.SS  wxNotifyEvent (wxEventType eventType = wxEVT_NULLint id = 0)

     


      Constructor (used internally by wxWidgets only).
     
    
   
  
.SS void Allow ()

     


      This is the opposite of
      Veto()
      : it explicitly allows the event to be processed. For most events it is
      not necessary to call this method as the events are allowed anyhow but
      some are forbidden by default (this will be mentioned in the corresponding
      event description).
     
    
   
  
.SS bool IsAllowed ()

     


      Returns true if the change is allowed (
      Veto()
      hasn't been called) or false otherwise (if it was).
     
    
   
  
.SS void Veto ()

     


      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.
