1.5 的新功能

Changes in 1.5

New features

Added documentation on porting Qt Quick Ultralite to new platforms, see the Qt Quick Ultralite 平台移植指南 .
添加图像 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 范例。
添加 QUL_DEFAULT_FONT_FAMILY 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 ，和 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 .
