## Detailed 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.

## Events using this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxFocusEvent& event)
Event macros:

- EVT_SET_FOCUS(func):
  Process a `wxEVT_SET_FOCUS` event.
- EVT_KILL_FOCUS(func):
  Process a `wxEVT_KILL_FOCUS` event.
