What's New in 1.5

Changes in 1.5

New features

  • Added documentation on porting Qt Quick Ultralite to new platforms, see the Qt Quick Ultralite Platform Porting Guide.
  • Added Image and ImageProvider APIs. Use them to register image providers for "image://provider/location" URLs and to display images that are loaded at runtime. See the image_loading example.
  • Added the MCU.Config.defaultFontFamily and QUL_FONTS_DIR CMake target properties. Using the CMake variables of the same name is now deprecated.
  • Added SDK v2.8.0 support for NXP MIMXRT1050-EVKB, MIMXRT1060-EVK, and MIMXRT1064-EVK.
  • Added 24bpp color depth support for NXP RT1050, RT1060, and RT1064. This requires platform adaptation for screen support though.

Source compatibility breaks

  • Flickable's contentX and contentY properties have flipped sign: Positive values move the content right or down respectively. This matches the behavior in Qt Quick's Flickable.

Fixed issues

  • Fixed redraw bug on the desktop backend (QTMCU-7)
  • Fixed bug that prevented anchors on the root item of a QML file from working.
  • Use of the rotation, scale, and transformOrigin properties in the root item of a QML file works now.
  • qul_target_generate_interfaces() CMake API no longer require adding additional include directories using target_include_directories or setting CMAKE_INCLUDE_CURRENT_DIR.
