NAME
wxFocusEvent - Functions for wxFocusEvent class
DESCRIPTION
A focus event is sent when a window's focus changes. The window losing
focus receives a "kill focus" event while the window gaining it gets a
"set focus" one.
Notice that the set focus event happens both when the user gives focus
to the window (whether using the mouse or keyboard) and when it is done
from the program itself using wxWindow:setFocus/1.
The focus event handlers should almost invariably call wxEvent:skip/2
on their event argument to allow the default handling to take place.
Failure to do this may result in incorrect behaviour of the native con-
trols. Also note that wxEVT_KILL_FOCUS handler must not call wxWin-
dow:setFocus/1 as this, again, is not supported by all native controls.
If you need to do this, consider using the Delayed Action Mechanism
(not implemented in wx) described in wxIdleEvent documentation.
See: Overview events
This class is derived (and can use functions) from: wxEvent
wxWidgets docs: wxFocusEvent
EVENTS
Use wxEvtHandler:connect/3 with wxFocusEventType to subscribe to events
of this type.
DATA TYPES
wxFocusEvent() = wx:wx_object()
wxFocus() =
#wxFocus{type = wxFocusEvent:wxFocusEventType(),
win = wxWindow:wxWindow()}
wxFocusEventType() = set_focus | kill_focus
EXPORTS
getWindow(This) -> wxWindow:wxWindow()
Types:
This = wxFocusEvent()
Returns the window associated with this event, that is the win-
dow which had the focus before for the wxEVT_SET_FOCUS event and
the window which is going to receive focus for the
wxEVT_KILL_FOCUS one.
Warning: the window pointer may be NULL!
