Qt Quick Widgets

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 .

典型用法：

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 被设为 SizeViewToRootObject , which will load the component and resize it to fit the view. Alternatively, you can set resizeMode to SizeViewToRootObject , which will resize the view to the root item.

使用模块

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake .

构建采用 CMake

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS QuickWidgets)
target_link_libraries(mytarget PRIVATE Qt6::QuickWidgets)

更多细节，见构建采用 CMake 概述。

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
