I don't believe it's possible and for good reason. A major
benefit/feature of UIManger is making actions independent of any given
widget, e.g. a menu item. When the notion of separated actions and
widgets introduced you can then combine them at will without having to
keep multiple widgets in sync. One reason I switched to UIManager was
the all too common scenario where an icon or label was modified in one
part of the UI but other parts of the UI (e.g. the same item in a popup
menu or a toolbar button) was forgotten about in the update leading to
inconsistencies in the UI. I really like the fact I change the
definition in exactly one place and every part of the UI is consistently
updated. That flexibility and consistency occurs because actions and
widgets are independent.
