In order to process the situation, when the button looses the focus, you may consider creating a callback function derived from control name.

 

  control add button name "myButton", hDlg, %controlMyButton, "", 5, 5, 100, 100

 

...

 

callback function myButton.OnKillFocus()

msgbox cbhndl, "The button with text " + myButton.Text + " lost focus!"

end function

 

Anytime this event happens, this function will be called and you can reach for standard callback parameters, such as cbhndl, from it.

 

But you will probably not even need it - due to control name global nature, you can also reference the control variable from there directly as well.
