# Qt Quick Widgets Example

Demonstrates how to mix Qt Quick with a Qt Widgets application using the QQuickWidget class.

The example demonstrates how you can embed Qt Quick scenes inside a Qt Widgets application, and how different UI aspects integrate between Qt Widgets and Qt Quick. This includes:

- Tab focusing between Qt Widgets and Qt Quick
- Embedding a QQuickView inside a QLayout

#### Running the Example

To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, see Qt Creator: Tutorial: Build and run.

#### Qt Quick view integration

To demonstrate seamless integration of Qt Quick view, the example implements several approaches of taking a screenshot of the Qt Quick view.

In the main menu, select File, then select any of these options to grab a screenshot of the Qt Quick view:

- Grab framebuffer - grabs the screenshot using the QQuickWidget::grabFramebuffer function.
- Render to pixmap - grabs the screenshot using the QWidget::render function and a QPixmap instance as a parameter. This approach is common for Qt Widgets.
- Grab via grabToImage - calls the `performLayerBasedGrab` function declared in the QML file. The `performLayerBasedGrab` function calls QML Item's Item::grabToImage function to grab the screenshot. This approach demonstrates how to call nested view's QML APIs from C++.

#### QQuickWidget in MDI

The example also demonstrates how you can use QQuickWidget to seamlessly integrate hardware accelerated Qt Quick scenes in a Qt Widget Multiple Document Interface (MDI) application.

To open a new MDI subwindow, in the main menu, select Window > Add tab widget.
