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 2 .
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 1.1
| ColorDialog | A native color dialog |
| Dialog | Base class of native dialogs |
| FileDialog | A native file dialog |
| FolderDialog | A native folder dialog |
| FontDialog | A native font dialog |
| Menu | A native menu |
| MenuBar | A native menubar |
| MenuItem | A native menu item |
| MenuItemGroup | A group for managing native menu items |
| MenuSeparator | A native menu separator |
| MessageDialog | A native message dialog |
| StandardPaths | Provides access to the standard system paths |
| SystemTrayIcon | A system tray icon |
注意： Types in Qt.labs modules are not guaranteed to remain compatible in future versions.
