[Qt-interest] If I start a long(ish) Qt drawing process, how can I know when it has completed?

[Atlant Schmidt]

Folks:

  Suppose I'm about to do a major screen rearrangement, perhaps
  displaying an entirely new screen using a layout that contains a
  variety of typical Qt widgets (frames, labels, pushbuttons, etc.).

  How can I find out when Qt has completed all of the re-painting that
  it needs to do to fully-present the new screen to the user?

  Background: I ask this because I'd like to discard enqueued mouse
  events ("mouse-ahead") which might have pertained to the old screen
  but are definitely not appropriate for the new screen.

                                          Atlant
