Detailed Description

The QLidReading class holds readings from the Lid sensor.

A normal laptop has what we call a front lid.

If the laptop can be converted to a tablet by rotating or closing the lid where the display is out, this is known as a back lid.

QLidReading Units

The Lid sensor can detect if a device's lid is closed or not. A lid can be a laptop, a laptop that converts to a tablet, or even a cover for a tablet or phone.

Property Documentation

backLidClosed : const bool

This property holds a value indicating whether the back lid is closed. A back lid can be when a convertable laptop is closed into to tablet mode without keyboard.

Access functions:

bool backLidClosed() const

See also QLidReading Units.

frontLidClosed : const bool

This property holds a value indicating whether the front lid is closed. A front lid would be a normal laptop lid.

Access functions:

bool frontLidClosed() const

Member Function Documentation

QLidReading::QLidReading(QObject *parent = DECLARE_READING(QLidReading))

Default constructs an instance of QLidReading.

[virtual] QLidReading::~QLidReading()

Destroys the instance of QLidReading. The destructor is virtual.

[override virtual] void QLidReading::copyValuesFrom(QSensorReading *other)

[signal] void QLidReading::frontLidChanged(bool closed)

void QLidReading::setBackLidClosed(bool closed)

Sets the backLidClosed value to closed.
