batteryState QML Value Type

Constants are chosen to match the enums in the linux kernel defined in include/linux/power_supply.h as of version 3.7 The one difference is for style reasons the constants are all uppercase not mixed case. More...

Detailed Description

batteryState is a structured value type usable in QML. It maps directly to the sensor_msgs::msg::BatteryState ROS 2 message type.

Construct a batteryState in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.
