QWidget::update crash in another thread

[waiter]

but I find QWidget::udpate just like
QApplication:ostEvent(frame, new UpdateVideoEvent(QRect(0,0,10,10)));

UpdateVideoEvent is QEvent(UpdateLater)

it just crash in QRegion::isEmpty(),

Hmm. What if you invoke the update method like this

QMetaObject::invokeMethod(frame, "update", Qt::QueuedConnection);

QMetaObject::invokeMethod(frame, "update", Qt::QueuedConnection);

To copy to clipboard, switch view to plain text mode
