Is there any way to tell what control is gaining focus when my control
loses it? In Swing, I could use the field FocusEvent.opposite. Is there
any equivalent for SWT?

Thanks

Try Display.getFocusControl(). If it doesn't in focusLost(), try such a
trick:

public void focusLost(FocusEvent event) {
final Display display = event.getDisplay();

display.asyncExec(new Runnable() {
public void run() {
Control focusControl
= display.getFocusControl();
...
}
}
}

The code will not be executed at once, but you won't see the difference,
and Display.getFocusControl() should return the right control.
