Description

TOnSensorChoosing is used for events that provide a list of sensors and expect an index of a selected sensor.

The TOnSensorChoosing type is used to handle the OnSensorChoosing event.

This type receives the following parameters:

• Sender is the object whose event handler is called. For example, for the OnSensorChoosing event of a location sensor, the Sender parameter is the location sensor.
• Sensors is a list of hardware sensors of the type of Sender available on the device running your application. For example, for the OnSensorChoosing event of a location sensor, the Sensors parameter is a list of hardware sensors that can provide location information.
• ChoseSensorIndex is the index of a sensor in the list of hardware sensors. Change this parameter to the index of the sensor that you want to use. The first sensor in the list of hardware sensors is used by default.
