NAME

       wxNotifyEvent - Functions for wxNotifyEvent class

DESCRIPTION

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

       It (or an object of a derived class) is sent when the controls state is being changed  and
       allows the program to veto/1 this change if it wants to prevent it from happening.

       See: wxBookCtrlEvent

       This class is derived (and can use functions) from: wxCommandEvent wxEvent

       wxWidgets docs: wxNotifyEvent

DATA TYPES

       wxNotifyEvent() = wx:wx_object()

EXPORTS

       allow(This) -> ok

              Types:

                 This = wxNotifyEvent()

              This is the opposite of veto/1: 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).

       isAllowed(This) -> boolean()

              Types:

                 This = wxNotifyEvent()

              Returns  true  if  the  change  is  allowed  (veto/1  hasn't  been called) or false
              otherwise (if it was).

       veto(This) -> ok

              Types:

                 This = wxNotifyEvent()

              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.
