## Property Documentation

### `[read-only, since 6.10]` contrastPreference : Qt::ContrastPreference

This property holds the contrast mode set by the system.

This property can be used by the application to determine what contrast settings the system is currently using.

Qt styles use this property in order to adjust palette colors and outlines.

This enumeration was introduced in Qt 6.10.

Access functions:

Qt::ContrastPreference | contrastPreference() const

Notifier signal:

void | contrastPreferenceChanged(Qt::ContrastPreference contrastPreference)

See also Qt::ColorScheme, QGuiApplication::palette(), and QEvent::PaletteChange.

### `[read-only, since 6.12]` motionPreference : Qt::MotionPreference

This property holds the motion preference set by the system.

This property can be used by the application to determine if the user interface should have fewer animated effects. Respecting this preference may make the application more accessible to those that suffer from vestibular motion disorders.

This enumeration was introduced in Qt 6.12.

Access functions:

Qt::MotionPreference | motionPreference() const

Notifier signal:

void | motionPreferenceChanged(Qt::MotionPreference motionPreference)

See also contrastPreference.
