Qt Widgets Designer is the Qt tool for designing and building graphical user interfaces (GUIs) with Qt Widgets 。對於用戶界麵設計，采用 Qt Quick ，見 Qt Design Studio .
You can compose and customize your windows or dialogs in a what-you-see-is-what-you-get (WYSIWYG) manner, and test them using different styles and resolutions. Widgets and forms created with Qt Designer integrate seamlessly with programmed code, using Qt's signals and slots mechanism, so that you can easily assign behavior to graphical elements. All properties set in Qt Designer can be changed dynamically within the code. Furthermore, features like widget promotion and custom plugins allow you to use your own components with Qt Designer.
注意： 可以選擇使用 Qt Quick and Qt Design Studio 用於用戶界麵設計而非 Widget。是更易於編寫多種應用程序的方式。它啓用完全可定製外觀、觸摸反應元素和平滑動畫過渡，利用硬件加速。
