Qt Widgets Designer is the Qt tool for designing and building graphical user interfaces (GUIs) with Qt Widgets 。对于用户界面设计，采用 Qt Quick ，见 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： 可以选择使用 Qt Quick and Qt Design Studio 用于用户界面设计而非 Widget。是更易于编写多种应用程序的方式。它启用完全可定制外观、触摸反应元素和平滑动画过渡，利用硬件加速。
