附加特性

• logicalPixelDensity : real (obsolete)

附加特性文档编制

The number of logical pixels per millimeter. This is the effective pixel density provided by the platform to use in image scaling calculations.

Due to inconsistencies in how logical pixel density is handled across the various platforms Qt supports, it is recommended to use physical pixels instead (via the pixelDensity property) for portability.

该 QML 特性在 Qt 5.1 引入。
