388/*!-
389 \class QQuickWidget-
390 \since 5.3-
391 \brief The QQuickWidget class provides a widget for displaying a Qt Quick user interface.-
392-
393 \inmodule QtQuickWidgets-
394-
395 This is a convenience wrapper for QQuickWindow which will automatically load and display a QML-
396 scene when given the URL of the main source file. Alternatively, you can instantiate your own-
397 objects using QQmlComponent and place them in a manually set up QQuickWidget.-
398-
399 Typical usage:-
400-
401 \code-
402 QQuickWidget *view = new QQuickWidget;-
403 view->setSource(QUrl::fromLocalFile("myqmlfile.qml"));-
404 view->show();-
405 \endcode-
406-
407 To receive errors related to loading and executing QML with QQuickWidget,-
408 you can connect to the statusChanged() signal and monitor for QQuickWidget::Error.-
409 The errors are available via QQuickWidget::errors().-
410-
411 QQuickWidget also manages sizing of the view and root object. By default, the \l resizeMode-
412 is SizeViewToRootObject, which will load the component and resize it to the-
413 size of the view. Alternatively the resizeMode may be set to SizeRootObjectToView which-
414 will resize the view to the size of the root object.-
415-
416 \note QQuickWidget is an alternative to using QQuickView and QWidget::createWindowContainer().-
417 The restrictions on stacking order do not apply, making QQuickWidget the more flexible-
418 alternative, behaving more like an ordinary widget. This comes at the expense of-
419 performance. Unlike QQuickWindow and QQuickView, QQuickWidget involves rendering into OpenGL-
420 framebuffer objects. This will naturally carry a minor performance hit.-
421-
422 \note Using QQuickWidget disables the threaded render loop on all platforms. This means that-
423 some of the benefits of threaded rendering, for example \l Animator classes and vsync driven-
424 animations, will not be available.-
425-
426 \note Avoid calling winId() on a QQuickWidget. This function triggers the creation of-
427 a native window, resulting in reduced performance and possibly rendering glitches. The-
428 entire purpose of QQuickWidget is to render Quick scenes without a separate native-
429 window, hence making it a native widget should always be avoided.-
430-
431 \section1 Scene Graph and Context Persistency-
432-
433 QQuickWidget honors QQuickWindow::isPersistentSceneGraph(), meaning that-
434 applications can decide - by calling-
435 QQuickWindow::setPersistentSceneGraph() on the window returned from the-
436 quickWindow() function - to let scenegraph nodes and other Qt Quick scene-
437 related resources be released whenever the widget becomes hidden. By default-
438 persistency is enabled, just like with QQuickWindow.-
439-
440 When running with the OpenGL backend of the scene graph, QQuickWindow-
441 offers the possibility to disable persistent OpenGL contexts as well. This-
442 setting is currently ignored by QQuickWidget and the context is always-
443 persistent. The OpenGL context is thus not destroyed when hiding the-
444 widget. The context is destroyed only when the widget is destroyed or when-
445 the widget gets reparented into another top-level widget's child hierarchy.-
446 However, some applications, in particular those that have their own-
447 graphics resources due to performing custom OpenGL rendering in the Qt-
448 Quick scene, may wish to disable the latter since they may not be prepared-
449 to handle the loss of the context when moving a QQuickWidget into another-
450 window. Such applications can set the-
451 QCoreApplication::AA_ShareOpenGLContexts attribute. For a discussion on the-
452 details of resource initialization and cleanup, refer to the QOpenGLWidget-
453 documentation.-
454-
455 \note QQuickWidget offers less fine-grained control over its internal-
456 OpenGL context than QOpenGLWidget, and there are subtle differences, most-
457 notably that disabling the persistent scene graph will lead to destroying-
458 the context on a window change regardless of the presence of-
459 QCoreApplication::AA_ShareOpenGLContexts.-
460-
461 \section1 Limitations-
462-
463 Putting other widgets underneath and making the QQuickWidget transparent will not lead-
464 to the expected results: the widgets underneath will not be visible. This is because-
465 in practice the QQuickWidget is drawn before all other regular, non-OpenGL widgets,-
466 and so see-through types of solutions are not feasible. Other type of layouts, like-
467 having widgets on top of the QQuickWidget, will function as expected.-
468-
469 When absolutely necessary, this limitation can be overcome by setting the-
470 Qt::WA_AlwaysStackOnTop attribute on the QQuickWidget. Be aware, however that this-
471 breaks stacking order. For example it will not be possible to have other widgets on-
472 top of the QQuickWidget, so it should only be used in situations where a-
473 semi-transparent QQuickWidget with other widgets visible underneath is required.-
474-
475 This limitation only applies when there are other widgets underneath the QQuickWidget-
476 inside the same window. Making the window semi-transparent, with other applications-
477 and the desktop visible in the background, is done in the traditional way: Set-
478 Qt::WA_TranslucentBackground on the top-level window, request an alpha channel, and-
479 change the Qt Quick Scenegraph's clear color to Qt::transparent via setClearColor().-
480-
481 \section1 Support when not using OpenGL-
482-
483 In addition to OpenGL, the \c software backend of Qt Quick also supports-
484 QQuickWidget. Other backends, for example the Direct 3D 12 one, are not-
485 compatible however and attempting to construct a QQuickWidget will lead to-
486 problems.-
487-
488 \section1 Tab Key Handling-
489-
490 On press of the \c[TAB] key, the item inside the QQuickWidget gets focus. If-
491 this item can handle \c[TAB] key press, focus will change accordingly within-
492 the item, otherwise the next widget in the focus chain gets focus.-
