Qt Widgets Designer Manual

Qt Widgets Designer is the Qt tool for designing and building graphical user interfaces (GUIs) with Qt Widgets. For user interface design with Qt Quick, see 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 Widgets 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 Widgets 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 Widgets Designer.

Note: You have the option of using Qt Quick and Qt Design Studio for user interface design rather than widgets. It is a much easier way to write many kinds of applications. It enables a completely customizable appearance, touch-reactive elements, and smooth animated transitions, taking advantage of hardware acceleration.

If you are new to Qt Widgets Designer, you can take a look at the Getting To Know Qt Widgets Designer document. For a quick tutorial on how to use Qt Widgets Designer, refer to A Quick Start to Qt Widgets Designer.
