Detailed DescriptionThe QOrientationReading class represents one reading from the orientation sensor. The orientation sensor reports the orientation of the device. As it operates below the UI level it does not report on or even know how the UI is rotated. Most importantly this means that this sensor cannot be used to detect if a device is in portrait or landscape mode. This sensor is useful to detect that a particular side of the device is pointing up. QOrientationReading UnitsThe orientation sensor returns the orientation of the device using the pre-defined values found in the QOrientationReading::Orientation enum. Member Type Documentation
|
| Constant | Value | Description |
|---|---|---|
| QOrientationReading::Undefined | 0 | The orientation is unknown. |
| QOrientationReading::TopUp | 1 | The Top edge of the device is pointing up. |
| QOrientationReading::TopDown | 2 | The Top edge of the device is pointing down. |
| QOrientationReading::LeftUp | 3 | The Left edge of the device is pointing up. |
| QOrientationReading::RightUp | 4 | The Right edge of the device is pointing up. |
| QOrientationReading::FaceUp | 5 | The Face of the device is pointing up. |
| QOrientationReading::FaceDown | 6 | The Face of the device is pointing down. |
It should be noted that the orientation sensor reports the orientation of the device and not the UI. The orientation of the device will not change just because the UI is rotated. This means this sensor cannot be used to detect if a device is in portrait or landscape mode.
