What's New in 1.6

Qt Quick Ultralite maintains source compatibility between minor releases. However, some changes may require you to adapt the application code accordingly. The following sections highlight such changes:

Changes in v1.6.0

New toolchains

  • Qt for MCUs now supports building applications using the IAR Toolchain for ARM V8.50. It provides prebuilt libraries and ready-made CMake integration for the supported boards. See Supported Target Boards and Development Hosts for the list.

New features

  • ListView and Repeater now have methods to access their contained items.
  • Key frames in a Timeline can now target string and boolean properties.
  • Added a new platform interface to enable implementing hardware accelerated blending of rounded rectangles on platforms which support it.


  • All examples included in the SDK now have documentation.

Fixed issues

  • Improved SwipeView's snappiness.
  • Fixed desktop builds using MSVC v14.27 or newer.
  • Fixed compilation errors when setting very large sizes on text elements.
  • Setting a Rectangle on a property declared as Item will not cause a compilation error anymore.
  • Fix compilation errors when setting padding and transform properties on an instance of a Text-based inline component.
  • Assets compressed using QUL_RESOURCE_COMPRESSION are now correctly read from flash memory and not preloaded into RAM anymore.
  • Changed the order of resolving bindings on application startup. All bindings are resolved first before calling Component.onCompleted for each object, followed by reevaluating the bindings again.
