The experimental Qt Labs Platform module provides QML types for native platform extensions. These QML types work in conjunction with Qt Quick and Qt Quick Controls .
可以使用以下 import 语句在 .qml 文件中把 QML 类型导入应用程序：
import Qt.labs.platform
| ColorDialog | A native color dialog |
| Dialog | Base class of native dialogs |
| FileDialog | A native file dialog |
| FolderDialog | A native folder dialog |
