NAME

6       wxEvent - Functions for wxEvent class
7

DESCRIPTION

9       An  event is a structure holding information about an event passed to a
10       callback or member function.
11
12       wxEvent used to be a multipurpose event object, and is an abstract base
13       class for other event classes (see below).
14
15       For more information about events, see the overview_events overview.
16
17       See: wxCommandEvent, wxMouseEvent

DATA TYPES

22       wxEvent() = wx:wx_object()
23

EXPORTS

25       getId(This) -> integer()
26
27              Types:
28
29                 This = wxEvent()
30
31              Returns  the  identifier  associated  with this event, such as a
32              button command id.
33
34       getSkipped(This) -> boolean()
35
36              Types:
37
38                 This = wxEvent()
39
40              Returns true if the event handler should be skipped, false  oth‐
41              erwise.
42
43       getTimestamp(This) -> integer()
44
45              Types:
46
47                 This = wxEvent()
48
49              Gets the timestamp for the event.
50
51              The  timestamp  is the time in milliseconds since some fixed mo‐
52              ment (not necessarily the standard Unix Epoch, so  only  differ‐
53              ences  between the timestamps and not their absolute values usu‐
54              ally make sense).
55
56              Warning: wxWidgets returns a non-NULL timestamp only  for  mouse
57              and key events (see wxMouseEvent and wxKeyEvent).
58
59       isCommandEvent(This) -> boolean()
60
61              Types:
62
63                 This = wxEvent()
64
65              Returns  true  if the event is or is derived from wxCommandEvent
66              else it returns false.
67
68              Note: exists only for optimization purposes.
69
70       resumePropagation(This, PropagationLevel) -> ok
71
72              Types:
73
74                 This = wxEvent()
75                 PropagationLevel = integer()
76
77              Sets the propagation level to the given value (for  example  re‐
78              turned from an earlier call to stopPropagation/1).
79
80       shouldPropagate(This) -> boolean()
81
82              Types:
83
84                 This = wxEvent()
85
86              Test  if  this  event  should  be propagated or not, i.e. if the
87              propagation level is currently greater than 0.
88
89       skip(This) -> ok
90
91              Types:
92
93                 This = wxEvent()
94
95       skip(This, Options :: [Option]) -> ok
96
97              Types:
98
99                 This = wxEvent()
100                 Option = {skip, boolean()}
101
102              This method can be used  inside  an  event  handler  to  control
103              whether  further  event  handlers  bound  to  this event will be
104              called after the current one returns.
105
106              Without skip/2 (or equivalently if  Skip(false)  is  used),  the
107              event  will  not be processed any more. If Skip(true) is called,
108              the event processing system continues searching  for  a  further
109              handler  function  for  this event, even though it has been pro‐
110              cessed already in the current handler.
111
112              In general, it is recommended to skip all non-command events  to
113              allow  the  default  handling  to take place. The command events
114              are, however, normally not skipped as usually a  single  command
115              such  as a button click or menu item selection must only be pro‐
116              cessed by one handler.
117
118       stopPropagation(This) -> integer()
119
120              Types:
121
122                 This = wxEvent()
123
124              Stop the event from propagating to its parent window.
125
126              Returns the old propagation  level  value  which  may  be  later
127              passed  to  resumePropagation/2  to  allow propagating the event
128              again.
