# Wx::FocusEvent

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 set_focus.

## Event table macros

To process a focus event, use these event handler macros to direct input to a member
function that takes a FocusEvent argument.

evt_set_focus() { | event | … } | Process a EVT_SET_FOCUS event.
evt_kill_focus() { | event | … } | Process a EVT_KILL_FOCUS event.
