window-focus-changed

Since: Version 20221119-145034-49b9839f

The functionality described in this section requires version 20221119-145034-49b9839f of wezterm, or a more recent version.

The window-focus-changed event is emitted when the focus state for a window is changed.

This event is fire-and-forget from the perspective of wezterm; it fires the event to advise of the config change, but has no other expectations.

The first event parameter is a window object that represents the gui window.

The second event parameter is a pane object that represents the active pane in that window.

local wezterm = require 'wezterm'

wezterm.on('window-focus-changed', function(window, pane)
  wezterm.log_info(
    'the focus state of ',
    window:window_id(),
    ' changed to ',
    window:is_focused()
  )
end)
