QML types 可以使用以下 import 语句导入应用程序，在 .qml 文件：

import QtQuick.Controls 2.12
							

C++ classes can be included into your application using the following include statement:

#include <QtQuickControls2>
							

To link against the corresponding C++ libraries, add the following to your qmake project file:

QT += quickcontrols2

从源代码构建

当从源代码构建时，确保 Qt Graphical Effects module is also built, as Qt Quick Controls 2 requires it.

Qt Image Formats module is recommended, but not required. It provides support for the .webp format used by the Imagine style .

版本

Qt Quick Controls 2.0 was introduced in Qt 5.7. Subsequent minor Qt releases increment the import version of the Qt Quick Controls 2 modules by one, until Qt 5.12, where the import versions match Qt's minor version. The experimental Qt Labs modules use import version 1.0.
