Qt Designer 5.11

Qt Designer is a visual interface builder for the Qt application framework, originally developed by Trolltech AS. It lets developers create cross-platform graphical user interfaces using a drag-and-drop workflow, assembling windows, dialogs, and forms from a rich set of Qt widgets. Designers can manage layouts, edit widget properties, define tab order, and connect signals and slots without writing boilerplate code. Projects are saved as .ui files (XML), which can be compiled into C++ with uic or loaded at runtime, making the tool equally useful for C++ and Qt bindings such as PyQt and PySide. Qt Designer supports custom widget promotion and plugins, style and platform previews, internationalization, and integration with Qt resources. It operates as a standalone utility and is also integrated into Qt Creator, streamlining design and development in a single environment. The result is a fast, consistent way to prototype, refine, and maintain Qt-based interfaces while adhering to best practices for layout and portability.
