NAME

6       wxNotifyEvent - Functions for wxNotifyEvent class
7

DESCRIPTION

9       This  class  is not used by the event handlers by itself, but is a base
10       class for other event classes (such as wxBookCtrlEvent).
11
12       It (or an object of a derived class) is sent when the controls state is
13       being  changed and allows the program to veto/1 this change if it wants
14       to prevent it from happening.
15
16       See: wxBookCtrlEvent
17
18       This class is derived (and can use functions) from: wxCommandEvent  wx‐
19       Event

DATA TYPES

24       wxNotifyEvent() = wx:wx_object()
25

EXPORTS

27       allow(This) -> ok
28
29              Types:
30
31                 This = wxNotifyEvent()
32
33              This  is  the opposite of veto/1: it explicitly allows the event
34              to be processed.
35
36              For most events it is not necessary to call this method  as  the
37              events  are  allowed  anyhow  but  some are forbidden by default
38              (this will be mentioned in the corresponding event description).
39
40       isAllowed(This) -> boolean()
41
42              Types:
43
44                 This = wxNotifyEvent()
45
46              Returns true if  the  change  is  allowed  (veto/1  hasn't  been
47              called) or false otherwise (if it was).
48
49       veto(This) -> ok
50
51              Types:
52
53                 This = wxNotifyEvent()
54
55              Prevents the change announced by this event from happening.
56
57              It  is  in general a good idea to notify the user about the rea‐
58              sons for vetoing the change because otherwise  the  applications
59              behaviour  (which  just refuses to do what the user wants) might
60              be quite surprising.
