Resize offscreen window when QQuickWidget is resized In a typical Qt Quick application, when a window is resized, the contentItem of that window is resized with it, and then the root item. QQuickOverlay in qtquickcontrols2 listens to size changes in the contentItem (QQuickRootItem) via addItemChangeListener(), as a cheap way (e.g. no signals) of knowing when to resize background dimming effects. It resizes the dimmer item to the size of the window. The first problem with QQuickWidget is that it only ever resizes the root item when using the SizeRootObjectToView resize mode, and not the contentItem. The second problem is that the root item is resized (via updateSize()) before the window itself even has a size (which happens in QQuickWidget::createFramebufferObject() via the call to d->offscreenWindow->setGeometry()). To demonstrate the second problem in detail, consider the following widget hierarchy (written in everybody's favorite language: QML): QMainWindow { QQuickWidget { QQuickWindow { // QQuickWidgetPrivate::offscreenWindow QQuickRootItem { // QQuickWindowPrivate::contentItem Page {} // QQuickWidgetPrivate::root } } } } The QMainWindow starts off as 200x200. When the window is resized, QQuickWidget::resizeEvent() is called. The first thing it does is call updateSize(), which in the case of SizeRootObjectToView, resizes the root item to 300x300. This causes QQuickOverlayPrivate::itemGeometryChanged() to be called, and the dimmers are resized to the size of the window, but the window still has its 200x200 size, as it is only updated later, when QQuickWidget::createFramebufferObject() is called. This patch fixes these issues by ensuring that contentItem and the window itself are resized along with the root item. As to why such manual intervention is necessary: from what I can see, it is because it's an "offscreen" window. This means that QWindowPrivate::platformWindow is null, and setGeometry() takes a different path that presumably results in no QResizeEvent being sent to the QQuickWindow. As QQuickWindow relies on resizeEvent() being called to resize its contentItem, the contentItem is never resized. With a typical Qt Quick application, all of this works as expected.

Resize offscreen window when QQuickWidget is resized In a typical Qt Quick application, when a window is resized, the contentItem of that window is resized with it, and then the root item. QQuickOverlay in qtquickcontrols2 listens to size changes in the contentItem (QQuickRootItem) via addItemChangeListener(), as a cheap way (e.g. no signals) of knowing when to resize background dimming effects. It resizes the dimmer item to the size of the window. The first problem with QQuickWidget is that it only ever resizes the root item when using the SizeRootObjectToView resize mode, and not the contentItem. The second problem is that the root item is resized (via updateSize()) before the window itself even has a size (which happens in QQuickWidget::createFramebufferObject() via the call to d->offscreenWindow->setGeometry()). To demonstrate the second problem in detail, consider the following widget hierarchy (written in everybody's favorite language: QML): QMainWindow { QQuickWidget { QQuickWindow { // QQuickWidgetPrivate::offscreenWindow QQuickRootItem { // QQuickWindowPrivate::contentItem Page {} // QQuickWidgetPrivate::root } } } } The QMainWindow starts off as 200x200. When the window is resized, QQuickWidget::resizeEvent() is called. The first thing it does is call updateSize(), which in the case of SizeRootObjectToView, resizes the root item to 300x300. This causes QQuickOverlayPrivate::itemGeometryChanged() to be called, and the dimmers are resized to the size of the window, but the window still has its 200x200 size, as it is only updated later, when QQuickWidget::createFramebufferObject() is called. This patch fixes these issues by ensuring that contentItem and the window itself are resized along with the root item. As to why such manual intervention is necessary: from what I can see, it is because it's an "offscreen" window. This means that QWindowPrivate::platformWindow is null, and setGeometry() takes a different path that presumably results in no QResizeEvent being sent to the QQuickWindow. As QQuickWindow relies on resizeEvent() being called to resize its contentItem, the contentItem is never resized. With a typical Qt Quick application, all of this works as expected.
