okee-dokee Jooel, OnGotFocus and OnLostFocus is implemented ... was testing using this script:

code:
Break On

$Form = CreateObject("Kixtart.Form")

$Form.Caption = "Kixforms..."
$Form.Width = 300
$Form.Height = 200

$Form.OnGotFocus = '$$Form.Caption = "GOT FOCUS"'
$Form.OnLostFocus = '$$Form.Caption = "LOST FOCUS"'

$Exit = $Form.CommandButton("Exit",,,100,25)
$Exit.OnClick = "Quit()"

$Exit.Center

$Form.Show(1)

While $Form.Visible
$=Execute($Form.DoEvents)
Loop

Exit 1

As one shifts the keyboard focus from window-to-window, watch the Kixforms titlebar for focus change information ...
