many widgets have When..., but no "sender" in it.
What's the preferred way to get "sender" control if one has many buttons linked to same callback?
There is an 'eventCtrl' in Ctrl and others though - but private.
GetFocus can't always be used.

One of aproaches would be to get it by thread, because
if used as static Ctrl::sender..., it's not thread safe(unlessOneUsesMutex,lock,etc).

2nd:
Can ui be done in other that main thread? on all platforms?
