附加特性文檔編製

[read-only] Screen.logicalPixelDensity : real

This property is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

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.

該特性在 Qt 5.1 引入。
