SimulatedLocationDataSource QML Type

The index of the item in the location collection that provides the current location.

You can get this value to find which item in the SimulatedLocationDataSource::locations collection represents the current location. You can also provide a new index to skip to a different location in the collection.

The rate over which the SimulatedLocationDataSource::locations collection is iterated.

This controls the frequency of location updates for the simulated location data source. The default value is 1.0, resulting in calls to AbstractLocationDataSource::updateLocation once per second. To increase the frequency, provide a higher value. A value of 2.0, for example, doubles the frequency of location updates. To slow down updates, provide a lower value. A value of 0.5, for example, decreases location updates by a factor of two. The iteration rate does not affect the Location::timestamp property of the items in the SimulatedLocationDataSource::locations (they are always 1 second apart).

A collection of locations that are iterated sequentially.

As the collection is iterated, the AbstractLocationDataSource::locationChanged signal is emitted for each location. The frequency at which AbstractLocationDataSource::updateLocation is called is determined by SimulatedLocationDataSource::iterationRate. Populate the collection by calling SimulatedLocationDataSource::setLocationsWithPolyline or by directly assigning a collection of Location to this property.

Emitted when the currentLocationIndex property changes.

Note: The corresponding handler is onCurrentLocationIndexChanged.

Emitted when the iterationRate property changes.

Note: The corresponding handler is onIterationRateChanged.

Emitted when the locations property changes.

Note: The corresponding handler is onLocationsChanged.

Creates a collection of locations using vertices from an input polyline.

The generated locations are available from the SimulatedLocationDataSource::locations property. The following location properties are populated based on the inputs:

• Location::timestamp
• Location::position
• Location::velocity

The Location::course property is calculated based on the inputs.

These location properties are not set:

• Location::horizontalAccuracy
• Location::verticalAccuracy
• Location::lastKnown

Creates a collection of locations along an input polyline based on simulationParameters.

The generated locations are available from the SimulatedLocationDataSource::locations property. Distance between each location on the polyline is determined by the value of SimulationParameters::velocity. If velocity is 10 meters per second, for example, the distance between locations will be 10 meters. The Location::timestamp values will always be 1 second apart.

The following properties will be set based on the inputs:

• Location::timestamp
• Location::position
• Location::velocity
• Location::horizontalAccuracy
• Location::verticalAccuracy

The Location::course property will be calculated based on the inputs. The Location::lastKnown property will not be set.
