[Qt-interest] resizing window signal

  Thank you, and that's a good thought but I can't accept
  that answer. Qt is *LOADED* with signals that most of
  us never catch most of the time and that happen far more
  frequently than the relatively-rare "window resize" events.
  So the processing wasted deciding that nobody's handling
  all of these other signals is far greater than would ever
  be wasted deciding that nobody's handling the "window resize"
  event.

  That may be closer to the true explanation but still,
  Qt generally encourages the use of signals and slots
  even within the same class. This feels like an
  unnecessary divergence from that general plan.

  I suspect the real answer is that this just never
  "bubbled up" high enough on the wish-list priority
  list to be worth an implementer's time.

  Maybe Thiago knows?

Because they are not for free, usually the client interested is the actual
subclass itself, and not too many people need it as a signal. At least,
that would be my guess, I am not a Troll.
