[CLOSED] Is there any way to know where the focus is going?

Is there any way to know where the focus is going?

When the cancel button is clicked, I do not want trigger the event Blur...
I do not want trigger this event when switching between windows...

<DirectEvents>
      <Blur OnEvent="GetDevedor">
           <EventMask ShowMask="true" Target="CustomTarget" CustomTarget="={#{wndDividas}.body}" />
     </Blur>
</DirectEvents>

Thanks for any help
