C
MCU.Config.fontHeapSize
Defines a maximum heap size for the font engine.
Description
The maximum amount of RAM (in bytes) that the font engine will use for its heap.
Since Qt Quick Ultralite 1.9, the heap buffer is preallocated by default, if a specific size is requested by MCU.Config.fontHeapSize
The default value is -1, which means that the heap usage is not restricted and therefore no buffer is preallocated in this case.
See MCU.Config.fontHeapPrealloc for instructions on how to disable preallocation.
See Text Rendering and Fonts for font engine-specific details.
Usage
This property is accepted in the main application .qmlproject
file, or BoardDefaults.qmlprojectconfig
for the target platform. It takes an integer, and the default value is -1.
Note: The property affects the Monotype Spark font engine only.
Code example:
MCU.Config { fontHeapSize: 12800 }
Since
This property was introduced in QmlProject API 1.3 .
