Qt 框架的主要用户界面技术是 Qt Quick Controls and Qt Widgets . Qt Quick Control interfaces are fluid, dynamic, and are best on touch interfaces. Qt Widgets are for creating complex desktop applications. You can create Qt Quick Controls and Qt Widgets interfaces with the target platform's native look and feel.
Qt Quick Controls is for creating dynamic and fluid user interfaces. The Qt Quick Controls module supplies QML types such as buttons, dialogs, and menus. You can use QML, a declarative language, to build the UI and JavaScript to implement the logic.
下表包含相关概述：
Qt Widgets are the user interface elements that are typical in desktop environments. The widgets integrate well to the underlying platform providing native look and feel on Windows, Linux and macOS. The widgets are mature and feature rich user interface elements suitable for mostly traditional user interfaces. In contrast to Qt Quick , the widgets are for creating large desktop applications and less suited for creating touch-centric applications with fluid interfaces.
以下列表包含 Qt Widgets 的相关概述：
