debugging widget hit test failing

hi

when using the widget reflector, a widget shows as painted but not hit testable, (and shows as visible under its properties,) what does it mean and what may be the cause?
how would one establish why it is not hit testable when it is supposed to?
i cant identify another (invisible) widget on top of it stealing the hit test

thanks

i have 2 widgets visible / in the viewport
in the widget reflector the one does not necessarily show as in front of the other
but when i hide the one widget, the other widget that was visible but not hit testable, becomes hit testable
is there another way to resolve priorities or conflicts in the viewport other than hiding widgets
i have tried setting the z order as part of but it does not seem to do what i want
