NAME
wxEvtHandler - The Event handler.
DESCRIPTION
The Event handler.
To get events from wxwidgets objects you subscribe to them by calling connect/[2-3].
Events are sent as messages, if no callback was supplied These messages will be #wx{}
where EventRecord is a record that depends on the event type. The records are defined in:
wx/include/wx.hrl.
If a callback was supplied to connect, the callback will be invoked (in another process)
to handle the event. The callback should be of arity 2. fun(EventRecord::wx(),
EventObject::wxObject()).
Beware that the callback will be in executed in new process each time.

EXPORTS
connect(This::wxEvtHandler(), EventType::wxEventType()) -> ok
Equivalent to connect(This, EventType, [])
connect(This::wxEvtHandler(), EventType::wxEventType(), Options::[Option]) -> ok
Types:
Option = {id, integer()} | {lastId, integer()} | {skip, boolean()} | callback |
{callback, function()} | {userData, term()}
This function subscribes the to events of EventType, in the range id, lastId. The
events will be received as messages if no callback is supplied.
Options: {id, integer()}, The identifier (or first of the identifier range) to be
associated with this event handler. Default ?wxID_ANY {lastId, integer()}, The
second part of the identifier range. If used 'id' must be set as the starting
identifier range. Default ?wxID_ANY {skip, boolean()}, If skip is true further
event_handlers will be called. This is not used if the 'callback' option is used.
Default false. {callback, function()} Use a callback fun(EventRecord::wx(),
EventObject::wxObject()) to process the event. Default not specfied i.e. a message
will be delivered to the process calling this function. {userData, term()} An
erlang term that will be sent with the event. Default: [].
disconnect(This::wxEvtHandler()) -> boolean()
Equivalent to disconnect(This, null, []) Can also have an optional callback Fun()
as an additional last argument.
disconnect(This::wxEvtHandler(), EventType::wxEventType()) -> boolean()
Equivalent to disconnect(This, EventType, [])
disconnect(This::wxEvtHandler(), EventType::wxEventType(), Opts::[Option]) -> boolean()
Types:
Option = {id, integer()} | {lastId, integer()} | {callback, function()}
See external documentation This function unsubscribes the process or callback fun
from the event handler. EventType may be the atom 'null' to match any eventtype.
Notice that the options skip and userdata is not used to match the eventhandler.
