Provides a C++ widget class for displaying a Qt Quick user interface.
The Qt Quick Widgets module is a convenience wrapper for
QQuickWindow . It will automatically load and display a QML scene when given the URL of the main
qml file. Alternatively, you can instantiate QML objects using
QQmlComponent and place them in a manually set-up
QQuickWidget *view = new QQuickWidget; view->setSource(QUrl::fromLocalFile("myqmlfile.qml")); view->show();
QQuickWidget also manages resizing the view and the root item. By default, the
resizeMode is set to
SizeViewToRootObject , which will load the component and resize it to fit the view. Alternatively, you can set
SizeViewToRootObject , which will resize the view to the root item.
Using the Module#
Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake .
Building with CMake#
find_package() command to locate the needed module component in the
find_package(Qt6 REQUIRED COMPONENTS QuickWidgets) target_link_libraries(mytarget PRIVATE Qt6::QuickWidgets)
For more details, see the Build with CMake overview.
Building with qmake quickwidgets#
To configure the module for building with qmake, add the module as a value of the
QT variable in the project’s .pro file:
QT += quickwidgets
