问题 I've been writing a GUI using the below setCentralWidget method (simplified here) for transitioning between frames - but didn't realize until pretty far in that it erased each window upon moving to the next (which I need to avoid). My actual code has entry boxes that need to be kept in their completed state for when the user goes back to that frame to revise, etc. I'd like to rewrite with as little change to my hierarchy as possible - most likely using QStackedWidget or something similar.

(Basically I want to change the

问题 I am trying to add a qquickwidget along with some other qwidgets in qstackedwidget. But when I am trying to set the current widget to the qquickwidget nothing appears on the window. Is there something else that need to be done? I am also setting the view property of the qquickwidget to true QQuickWidget* mRoom = new QQuickWidget; connect(mRoom, SIGNAL(statusChanged(QQuickWidget::Status)), this, SLOT(StatusChanged(QQuickWidget::Status))); mRoom->setSource(QUrl::fromLocalFile("C:/Users/visjain
