Re: [Interest] Update widget geometry BEFORE window shown

[David M. Cotter]

OMG I FIGURED IT OUT!!!

                        qWidgetP->setAttribute(Qt::WA_DontShowOnScreen, true);
                        qWidgetP->show();
                        QtLetTimersFire(0);
                        qWidgetP->hide();
                        qWidgetP->setAttribute(Qt::WA_DontShowOnScreen, false);


And here is QtLetTimersFire for completeness.

void    QtLetTimersFire(
        CFTimeInterval  durationT,              //      = 0.1
        bool            all_eventsB,    //      = false
        bool            extrasB)                //      = false
{
        //      don't let timers fire when this thread IS a timer
        if (!IsCooperativeThread()) {
                QEventLoop                      loop;           //      MUST be 
on the stack for events to flow!
                QEventLoop::ProcessEventsFlags  flags(
                        all_eventsB ? QEventLoop::AllEvents : 
QEventLoop::ExcludeUserInputEvents);

                CT_Timer::AvoidRecursiveTimer();

                if (durationT) {
                        CFTimeIntervalMilliseconds      
milliSecT(CFSecondsToMilliseconds(durationT));

                        if (extrasB) {
                                flags |= QEventLoop::WaitForMoreEvents | 
QEventLoop::EventLoopExec;
                        }

                        loop.processEvents(flags, milliSecT);
                } else {
                        loop.processEvents(flags);
                }
        }
}
