NAME

6       wxEvtHandler - Functions for wxEvtHandler class
7

DESCRIPTION

9       A  class  that can handle events from the windowing system. wxWindow is
10       (and therefore all window classes are) derived from this class.
11
12       To get events from wxwidgets objects you subscribe to them  by  calling
13       connect/3.
14
15       If the callback option is not supplied events are sent as messages.
16
17       These messages will be #wx{} where EventRecord is a record that depends
18       on the wxEventType. The records are defined in: wx/include/wx.hrl.
19
20       If a callback was supplied to connect, the callback will be invoked (in
21       another  process)  to handle the event. The callback should be of arity
22       2.
23
24       fun Callback (EventRecord::wx(), EventObject::wxObject()).
25
26       Note: The callback will be in executed in new process each time.

169              This function subscribes to events.
170
171              Subscribes to events of type EventType, in the range id, lastId.
172
173              The events will be received as messages if no callback  is  sup‐
174              plied.
175
176              Options
177
178              id:{id,  integer()}   The identifier (or first of the identifier
179              range) to be associated with  this  event  handler.  Default  is
180              ?wxID_ANY
181
182              lastid:{lastId,integer()}    The  second  part of the identifier
183              range. If used 'id' must  be  set  as  the  starting  identifier
184              range. Default is ?wxID_ANY
185
186              skip:{skip,boolean()}    If  skip is true further event_handlers
187              will be called. This is not used if  the  'callback'  option  is
188              used. Default is false.
189
190              callback:{callback,function()}       Use   a   callbackfun(Even‐
191              tRecord::wx(),EventObject::wxObject())  to  process  the  event.
192              Default  not  specified  i.e. a message will be delivered to the
193              process calling this function.
194
195              userData:{userData,term()}  An erlang term  that  will  be  sent
196              with the event. Default: [].
197
198       disconnect(This :: wxEvtHandler()) -> boolean()
199

206                     boolean()
207
208              Types:

210                 Option =
211                     {id,  integer()} | {lastId, integer()} | {callback, func‐
212                 tion()}
213
214              This function unsubscribes the process or callback fun from  the
215              event handler.
216
217              EventType  may be the atom 'null' to match any eventtype. Notice
218              that the options skip and userdata is  not  used  to  match  the
219              eventhandler.
