[Qt-interest] [Qt/Mac] Stuck with user focus

[Frank Mertens]

Oh, focus handling can run you mad!-)
Watch out window flags Qt::Tool, Qt::FramelessWindowHint for your
on-screen keyboard.
Maybe QApplication::focusChanged(QWidget*,QWidget*) [signal] and
QWidget::focusProxy() may also be your friends in tricking the
focus policy.
The undesired effects of your mouse clicks you could filter with
an event filter ala QWidget::eventFilter().
More tricks I don't know.

Good luck,
