What's New in 1.8
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:
New features
- Added API to drive main loop from application code
- Added QtQuick Ultralite Shapes API for vector graphics, with implementation for NXP's i.MX RT1170.
- Added support for Renesas EK-RA6M3G Evaluation Kit. Use the
QUL_PLATFORM=EK-RA6M3G-baremetalCMake option to configure your project for this platform. - Added IAR compiler toolchain support for i.MX RT1170.
- Added support for building Qt Quick Ultralite as a static library to enable integrating with an existing project.
- Added RGB332 pixel format to support 8-bit images.
- Added the QUL_GLYPHS_COPY_TO_RAM and QUL_FONT_FILES_COPY_TO_RAM CMake target properties to configure glyph and font file run-time storage.
Fixed issues
- Removed the refreshInterval variable on i.MX RT1170 to avoid compilation failure using the IAR toolchain.
- Removed expiry time for Renesas RH850-D1M1A binaries built using Green Hills.
- Refactored input event handling, separating the event filtering and acceptance logic.
- Documented the FreeRTOS directory name changes between the NXP SDK versions.
- Fixed flickering on STM32H750B-Disco.
- Changed example kit extension in the shipped packages.
- Added the fallback renderer as default for the blendImage function on STM32.
- Fixed issue where the Monotype Spark font engine integration was bypassing glyph cache and therfore would affect run-time performance.
Other changes
- Fixed the version number in the kit description files for the Arm GCC and GreenHills toolchain.
